First Words

Leaping forward

Since most dental procedures inevitably generate aerosols that can put dental professionals

at high risk of acquiring the virus, the early days of the pandemic required them to close their

clinics and only attend to emergency cases.

However, as the industry adapts, dental professionals are now able to deliver dental care

through reduced contact with patients while streamlining their procedures, all without

compromising their safety.

For instance, Dr Ryan Tse from Hong Kong (p.24) and Dr Suchada Kongkiatkamon from

Thailand (p.20) share how digitalising their practices benefitted them and their patients in

these trying times.

Dr Marie Fluent from the United States underscores the need for quality assurance measures,

recommended by the Centers for Disease Control, to ensure instrument sterility as well as

instil a sense of calm and confidence in the dental team in case of procedural error (p.44).

In fact, the digitalisation of the industry also highlighted more dental innovations as featured

in this issue.

COVID-19 infection rate among dentists in the United States remains lower

than other health professionals

The cumulative COVID-19 infection

prevalence rate among United States (US)

dentists was 2.6% as of November 2020 —

lower than the infection rate of other frontline

healthcare professionals, including nurses

and physicians, according to a study from

the American Dental Association Science and

Research Institute and Health Policy Institute.

The study “COVID-2019 Among Dentists in

the United States: A 6-Month Longitudinal

Report of Accumulative Prevalence and

Incidence,” published in the June issue of The

Journal of the American Dental Association,

is based on online survey data collected from

8 June to 13 November 2020, from 2,196 US

dentists in private practice or public health

about the COVID-19 testing they received, the

symptoms they experienced and the infection

prevention procedures they followed in their

primary practice.

Dentists’ COVID-19 incidence rates ranged

from 0.2% to 1.1% each month, and the

average incidence rate over the six months

was 0.5%. In May 2020, a survey of US

frontline healthcare workers, including

nurses and physicians, found their reported

COVID-19 prevalence rate to be 29%.

Of the initial 2,196 respondents, 1,291

participated in the final survey and 785

participated in all six. Fifty-seven dentists

in total reported ever receiving a COVID-19

diagnosis. The likely source of COVID-19 was

identified via contact tracing by a health

agency or clinic in 23 of those cases, with

the dental practice identified as the likely

infection source in two instances.

Because many dental procedures generate

aerosols, practicing dentistry was originally

believed to present a high risk of transmitting

SARS-CoV-2 to dental professionals.

During the study period, the rate of dentists

performing aerosol-generating procedures

increased from 92.8% in the first month to

98.4% in the last.

At least 99.7% of dentists said they used

enhanced infection prevention and control

strategies in their practice each month. A large

number of dentists reported screening patients

and staff for COVID-19, disinfecting between

patient appointments and encouraging social

distancing among patients.

Strategies to optimise personal protective

equipment (PPE) supplies, such as not

changing masks after each patient

appointment, were encouraged by the Centers

for Disease Control and Prevention (CDC)

when supplies were limited. Over the course

of the study, dentists’ use of these strategies

decreased, as more changed their masks with

every patient. After the first month, during

which 17.6% reported changing their masks

between patients, the rate never fell below

25.5% in subsequent months. ■

AG.Live: The 360-degree service for digital infrastructure

As a pioneer in dental CAD/CAM technology,

Amann Girrbach supports laboratories in

organising digital dental workflows. With

the AG.Live digital platform, this project has

reached a new dimension.

AG.Live helps dental technicians to manage

all digital activities locally and to connect with

an ever expanding global network of digital

dental professionals.

Patient case management is at the core of

the platform, which replaces the previous

C3 customer portal where the patient case

is created, managed and processed digitally.

Patient cases can be shared with partner

laboratories for further processing and in the

foreseeable future, exchanged between the

dentist and the laboratory.

Not only will laboratories and clinicians be

networked, but machines and materials too.

For example, to access material availability

or, in the future, to the operating modes of

milling machines and many other relevant

factors of a dental fabrication process.

Thus, AG.Live will be able to keep track of all

digital activities from one place — anywhere

and any time.

In doing so, it is Amann Girrbach’s intention to

create a network of optimised as well as new

partnerships. Network participants will be

able to work and collaborate more efficiently,

to focus on their strengths and thus better

position themselves in the market.

This management portal, which is unique on

the market in terms of scope, breaks down

the linearity of dental restoration processes.

Cross-linking into patient cases is now

possible in a simple and straightforward

manner by making patient data centrally

accessible and editable.

The linking of previously separate data

sources creates synergistic effects from

which AG.Live users can profit sustainably

and gain a noticeable competitive advantage.

In a further step, Amann Girrbach will

implement access to the company’s own

“AG Academy” training portal with numerous

training and further education opportunities

as well as an extensive archive of webinars

and tutorials. ■

Dentsply Sirona and 3Shape announce strategic partnership

our goal of tailoring our product solutions

to the needs of our customers. We want

to give dental professionals real added

value with digital technologies that can

be easily integrated and are an intelligent

advancement in their routine workflows,” said

Don Casey, chief executive officer of Dentsply

Sirona. “Open systems allow the integration

of new functions into existing practice and

laboratory structures. We are convinced

that we have an excellent partner for this

with 3Shape and look forward to additional

“3Shape’s goals and solutions are based

on an open ecosystem philosophy and on

working together with other companies

to provide better and more cost-effective

solutions that will benefit clinicians and

their patients,” said Jakob Just-Bomholt,

chief executive officer of 3Shape. “We’re

very excited that TRIOS users can now take

advantage of the leading SureSmile Aligners

treatment through a smoother workflow.”

Due to the different approval and registration

times, not all technologies and products are

immediately available in all countries. ■



DentalMonitoring continues to

disrupt the orthodontic market

with AI-powered solutions for

braces and aligners of all brands

has been the market leader since 2014 is revolutionising the industry

once again with the only available artificial intelligence (AI) based

virtual monitoring solution applicable to both aligner and braces

treatments of all types and brands.

In an industry where a vast majority of practices are mixed users,

the DentalMonitoring’s solution now allows dental professionals

— whether in private practices or dental service organisations

(DSO)— to take full control of their aligner and braces cases. As a

result, DentalMonitoring expands its addressable market to about

75%, helping more practices scale up their business, become more

efficient and deliver an outstanding patient experience.

Brilliant dental restorations

press ceramics

“Our solution has made yet another major breakthrough, and we

are proud to unveil a new suite of functionalities of our platform,”

said Philippe Salah, chief executive officer of DentalMonitoring.

Dental professionals can now monitor all their aligner and braces

cases independent of brand with the same, highly scalable AIdriven

workflow. In addition to monitoring treatment progress, they

can now actively define and monitor clinical goals for each patient.

This results in more active control, productivity and a new level of

safety and confidence for their practice: a real mindset shift for our


Salah, continued: “Doctors now have complete control over all

orthodontic treatment and can automatically track inter arch

parameters such as the overbite, the overjet, the transverse or class

correction of patients or detect the archwire and auxiliaries passivity

in addition to the intra arch parameters they were already able

to track with our solution. Dental professionals can virtualise and

automate all non-clinical procedures and schedule appointments

only when needed. At the same

time, the patients’ compliance and

engagement are improved, thanks to

the complete revamping of our highly

rated patient app.”

As the demand for remote care

technology increases within the dental

industry, DentalMonitoring continues

to lead the way with its virtual practice

solutions designed to engage, convert

and monitor patients. ■

Dentsply Sirona exclusively provides state-of-the-art equipment for new

dental department of MedPark Hospital in Bangkok, Thailand

MedPark Hospital in Bangkok, Thailand,

is one of the top hospitals for patient care

in South East Asia. The intention is for the

hospital to be the best provider of medical

treatments in the region. The new hospital

will provide quaternary care – an extension of

tertiary care – which is even more specialised,

such as for experimental medicine and

procedures or specialised surgeries.

Not every hospital can offer that level of

care. For this reason, installing modern

equipment was given a high priority. Dentsply

Sirona proved to be a partner with first-class

competence in consulting and planning for

such a project as well as being a full-service

provider of complete end-to-end solutions.

MedPark Hospital is equipped with six Sinius

and three Intego Pro treatment centres. The

SiroLaser Blue, the autoclave DAC Universal,

the imaging device Orthophos S 3D, Xios

Scan and Xios sensors, and a Heliodent Plus

were also integrated into the facility, along

with various Dentsply Sirona Restorative

products to provide the best possible

healthcare to patients to give them back their


In the second phase of the project, MedPark

Hospital was equipped with everything

needed for completely digital dentistry,

including the CEREC system with the intraoral

scanner CEREC Primescan and the new

milling unit CEREC Primemill. This enables

the hospital to provide chairside restorative

treatment for its patients.

Also, Astra Tech Implant System EV and

several Dentsply Sirona Endodontics products

such as ProTaper Next and K-File were

delivered for best-practice dental solutions.

In time, the plan for MedPark Hospital is to

also become an important location for clinical


“We are very pleased with the support of

our partner Dentsply Sirona in helping us

to succeed in establishing a modern health

care center,” said Dr Sonthi Sirimai, head of

Dental Department of MedPark Hospital, at

the recent opening ceremony. “It is good to

know that our teammates will now be able

to treat their patients using state-of-the-art

equipment with first-class instruments and

materials.” ■

Sources of SARS-COV-2 and other microorganisms in dental aerosols

COVID-19 was declared a pandemic in March

2020. Given the incomplete understanding

of the transmission of SARS-CoV-2 at that

time, the American Dental Association (ADA)

recommended that dental offices refrain from

providing non-emergency services. As a

result, 198,000 dentists in the United States

(US) closed their doors to patients.

The study “Sources of SARS-CoV-2 and Other

Microorganisms in Dental Aerosols”, published

in the Journal of Dental Research (JDR),

sought to inform infection-control science by

identifying the source of bacteria and viruses

in aerosol-generating dental procedures.

Researchers at The Ohio State University

College of Dentistry, Division of

Periodontology, Columbus, US, tracked the

origins of microbiota in aerosols generated

during treatment of 28 patients undergoing

ultrasonic scaling, implant osteotomy or

restorative procedures by combining reverse

transcriptase qPCR, to identify and quantify

SARS-CoV-2, and 16S sequencing, to

characterise the entire microbiome, with finescale

enumeration and source-tracking.

Thirty minutes following the procedure,

condensate was collected from the operator

and assistant’s face shield, the patient’s chest

and an area six-feet distant from the site of

operation. The results show that it is possible

to trace the source of contamination through

DNA microbiome analysis and that the major

source of microbes in aerosols came from the

dental irrigant.

Saliva did not significantly contribute as

infection control measures such as preoperative

mouth rinses and intra-oral highvolume

evacuation were used. The authors

conclude that the risk for transmission of

SARS-CoV-2 and other respiratory pathogens

from aerosolised saliva in dental operatories

is moderately low and that current infection

control practices are adequately robust to

protect personnel and patients alike. ■

FDI World Dental Federation Sustainability in dentistry initiative unites

eco-conscious dental industry partners around a common aim

FDI World Dental Federation (FDI) has

launched a new initiative, with commitments

from four founding industry partners –

Colgate, Dentsply Sirona, GSK Consumer

Healthcare, and TePe – to lead the charge on

sustainability in dentistry.

Over the next two years, FDI will work

collaboratively with its partners and other

key stakeholders to map out strategies and

implement solutions to help reduce the

environmental impact of dentistry and the

dental industry.

The work will lead to the publication of an

FDI Sustainability Code of Practice that

provides guidelines and objectives for

achieving a sustainable procurement and

supply procedure, which will be signed by cosignatories

across the supply chain.

Environmental sustainability in dentistry

is multifaceted and involves numerous

stakeholders. CO 2

emissions, plastics use,

waste generation and other environmental

impacts are major challenges at all levels of

the dental resource supply chain as well as in

care delivery.

Reducing the impact of the dental profession

on the environment will require action and

collaboration from many different actors. The

four founding partners are part of a proactive

approach to tackling these environmental

threats and developing concerted and farreaching


The project will also equip dentists and their

teams with a suite of tools and resources

to help them improve sustainability in their

dental practices while informing the general

public of their role in sustainability in dentistry

through improved oral health and making

informed decisions.

“I am delighted to witness FDI’s Sustainability

in Dentistry project evolve into this highcalibre,

multi-partner initiative to achieve our

sustainability goals for the dental profession,”

said Dr Gerhard K. Seeberger, president of

FDI. “The project’s humble beginnings as a

way to encourage oral health professionals

and dental practices to ‘think green’ is now

moving into a phase of collaboration, action

and real results.” ■

The German dental industry looks to the current year with confidence

At the European press conference in

preparation for the 39 th International Dental

Show (IDS), Mark Stephen Pace, chairman of

the board of the Association of the German

Dental Industry (VDDI), was nevertheless

confident about the future economic

situation of the German dental industry in

view of the significant decline in sales in the

2020 financial year.

The association’s trust survey from the

beginning of 2021 shows the following

picture: In 2020, for the first time since 2015,

the VDDI member companies generated a

total turnover of less than €5bn (€4.82bn).

It was 13.1% below the 2019 result. Almost

€2.92bn of this was earned on the export

markets, a decrease of 16.5%.

The domestic market developed much more

robustly than the export markets. Domestic

sales in 2020 amounted to €1.90bn, 7.3%

below the comparable sales figure for the

previous year. Slightly more than two thirds

of the companies surveyed by the Dental

Association posted lower sales in Germany

than in 2019.

According to Pace, some companies will

still have to go back to 2019 levels. The

companies’ expectations for the current

financial year and IDS year 2021 now speak

of a positive general mood. The 51% of the

member companies forecast sales increases

for the entire trade fair year and a further 42%

forecast sales at the previous year’s level.

The results of the recently evaluated VDDI

economic barometer from the spring also

confirm the positive assessments and

expectations of the German dental industry

for the current year 2021.

In terms of domestic sales for the first half of

2021, almost 69% of those surveyed expect

higher sales compared to the same period of

the previous year. For the export business,

almost 70% of the participants anticipate

sales increases in this period.

The 39 th IDS from 22 to 25 September 2021

will play an important role in the further

progress of oral and dental health. ■

Mr Sameer Merchant, chief executive officer of Laxmi Dental Group

Achieving 250% business growth

with an innovative business

model and customer service focus

In five years, Illusion Dental Laboratory, a subsidiary of Laxmi Dental

Group in India, achieved 250% business growth and doubled its

workforce from 950 to over 1,800. The group’s chief executive officer

and laboratory owner, Mr Sameer Merchant, gives light to this success.

In 2001, Mr Sameer Merchant joined

Laxmi Dental Group, an India-based

dental conglomerate.

For the past two decades, his visionary

leadership and fervor for technology

have led Laxmi Dental Group through

continuous growth and evolution. In fact,

the group has evolved from a homegrown

two-member dental lab to a

cohesive multi-faceted integrated group

with a presence in over 26 countries.

The company offers holistic vertically

integrated services, be it the fullservice

dental laboratories in India with

outsourcing hubs in the United States

(US) and United Kingdom (UK) or a dental

software service catering to the global

dental community with design support,

it has a well-established distribution

network for clinical, lab and dental


In fact, Mr Merchant’s goal is to have India

known as a supplier of superior quality

dental restorations. He is constantly

investing in the most advanced digital

workflow, equipment and technology to

ensure fast, accurate and predictable

results — all reflected in the success of

Laxmi Dental Group and Illusion Dental

Laboratory, its Indian subsidiary.


When digital dentistry revolution started

in the United States, Mr Merchant foresaw




that it was only a matter of time before it

came to India. So, about seven years ago,

he fully adopted the digital workflow in his

Illusion Dental Laboratory and partnered

with 3Shape — taking the business to the

next level.

Mr Merchant, said: “The software and

quality of the hardware propelled a multifold

growth. We made a tremendous

investment and saw a 100% ROI (return

on investment). And because of that, we

have been investing more, including a

plan to purchase 125 TRIOS scanners this

to address commonly asked questions

such as “How the process is like?” or “How

long does it take to do the scan?”

“There are a lot of dentists who have

the capital to buy a scanner but are

questioning the need to experience

the ‘pain’ of change. Because of this,

it is important that we send a trained

dental professional to do a demo of the

scanners,” explained Mr Merchant.

He noted that only 30-40% of clients

want to use the scanner while others

prefer to observe.

“Either way, the clients get to see the

quality of the scan and how easy the

process is; giving the assurance that

intraoral scanners are something worth

investing in,” he shared.

“I believe that once you get into the habit

of digital dentistry, it will be hard to go

back to analogue. Once our clients see

the results and how beneficial digital

workflow is, they will become more

interested to buy their own scanner,” he



In India, as around the world, the

scanners are considered expensive.

In order to support the dentists, Mr

Merchant bundles other products into the

deal to subsidise the cost.

“Dentists buy an intraoral scanner to

grow their practice. By helping them to

purchase a scanner, we are aiding them

in adopting a digital workflow to grow

the business. In turn, Illusion Dental Lab

gains business by being their partner. It is

a win-win situation,” he explained.

With Mr Deichmann’s encouragement, he

launched his innovative business model

(Fig. 1).



Branding his business model as the

“E & E”: Education and Experience, Mr

Merchant hired 30 young dentists in 20

different cities to act as digital dentistry


Each dentist has a 3Shape TRIOS

intraoral scanner and visits local dental

clinics personally to provide scanning

services, which includes but not limited

to checking the tooth prep and occlusion;

and sending the scans back to the lab.

“Our trained and qualified dentists are

tasked to educate fellow practitioners

on digital dentistry as well as to provide

guidance on how to use the scanner,”

explained Mr Merchant.

In fact, Illusion Dental Lab has a client

who used to manage one clinic. After

purchasing the 3Shape TRIOS intraoral

scanner, the business grew tremendously

that in just a year and a half, the clinic

has now four branches — the client even

purchased an additional scanner.

“Most dentists are excited about the

results of going digital and these new

technologies have completely changed

the way they do dentistry,” he shared.

The dentists could have never imagined it

to be so simple and their clinic assistants

and patients benefit from it as well. This

is on top of their practice growth of 30-



Mr Merchant also supports the

professional dive into digital dentistry by

emphasising on customer support. This is

done so by having an IT team on standby.

“The key for us is providing great

support. We understand that investing in

our customers will be constantly worried

about their purchase,” he remarked.

The team has four IT technicians as

well as dentists who act as support too.

In fact, Illusion Dental Lab is the only

company in India with 30 on-call dentists,

making it possible to solve customer

issues within two hours.

“Because we are based locally, we do not

need to bring doctors out to our corporate

office. We can provide our clients the

needed services in their own clinic,” said

Mr Merchant.


Illusion Dental Laboratory also has

another key differentiator. As a lab,

by necessity, there is a need to keep

up to date with the latest software

and workflows and have deeper

understanding of it.

Through these hands-on experiences, it

places the laboratory in a better position

to teach the software and workflow to the

digital dentistry which targets the local


“Digital dentistry plays a major role in

improving the entire workflow: from

clinics to laboratories, especially in

growing practices. It is here to stay and it will

only grow,” he said. “In fact, it is growing at a

faster pace than expected in India. Of course,

COVID-19 has been a roadblock but we’re

positive that it’ll get back on track.”

Although his innovative business model has

been successful in driving digital dentistry

and his company’s growth in India, Mr

Merchant never loses sight of what Illusion

Dental Laboratory is all about.

He concluded: “Our mission at Illusion Dental

Laboratory is to provide only the highest

quality dental restorations delivered in a

timely fashion with attentive customer

service. We strive to provide the perfect blend

of technical expertise, personal service, and

dependable results. We strongly believe in

relationships based on communication and

Dental Profile

Mr Heikki Kyöstilä,

CEO and founder of


Planmeca: Fifty

years changing the

face of dentistry

Planmeca was founded by Mr Heikki

Kyöstilä in Helsinki, Finland, in 1971. From

developing dental stools and cabinets to

becoming the owner of the largest private

dental manufacturing company in the

world, his journey – Planmeca’s journey −

is definitely worth sharing and celebrating.

This is the story of the chief executive

officer and founder of the company.



Mr Heikki Kyöstilä began his career as

a sales representative for a Finnish

dental supply company in 1965, right

after graduating from business college

– making him familiar with dental clinics

and their equipment early on. However,

it did not take long for the businessminded

future entrepreneur to realise

that the products he was selling could

be improved in many ways.

“I noticed that especially the patient

chairs – their design and ergonomics

– could easily be improved. At the

time, almost all dental products sold in

Finland were imported from Germany, so

I thought why not do something about it

and start making products of our own,”

he shared.



The first five years were pure survival

as the Finnish banks did not easily

grant loans to start-up companies, so

Mr Kyöstilä was financially on his own –

with an initial capital of 5,000 Finnish

marks (about the equivalent of today’s

€7,000*) which he earned by selling his

sail boat.



Dental Profile

The beginning was modest – he was

manufacturing dental stools and

instrument cabinets in a garage in

eastern Helsinki. But Mr Kyöstilä was

able to see the bigger picture and

immediately headed for the international

market, understanding from the get-go

that the Finnish dental market was

simply not big enough to build upon.

His foresight formed the backbone of

the company’s future success. In 1971,

the year that Planmeca was founded,

Mr Kyöstilä exhibited his first ergonomic

dental stool and an instrument cabinet

at the International Dental Show (IDS)

dental trade fair in München, Germany.

The demand was immediate, and orders

came in from around the world.

Mr Kyöstilä, said: “Finland was quite

unknown globally, and many customers

had no idea where we were located.

So, it took some time for us to establish

ourselves on the market. We had to work

really hard to put Finland on the map.

I often say that the beginning was like

skydiving without a parachute, but the

jump really paid off.”

and sophisticated technology.

From then on, it was one technological

breakthrough after another: the world’s

first microprocessor-controlled patient

chair and dental unit in 1983 and 1986,

respectively, followed by the world’s first

microprocessor-controlled panoramic

X-ray unit.

The 1980s was also the decade when

Planmeca’s university collaboration

began with an extensive equipment

delivery to the dental faculty of the

University of Helsinki.

In fact, Planmeca is now the choice

for over 300 dental schools worldwide,

and the company works in close

collaboration with university staff and


In 1983, the company entered the

United States (US) market with the sales

of 10,000 patient chairs.

This, together with the company’s

record-breaking delivery agreement of

over 1,000 dental units to Saudi Arabian

dental institutions in 2012, continue to

be the largest individual sales deals in

the history of dentistry.



In 1990, Planmeca challenged traditional

dentistry with new innovations. The

company went digital, leading to the

world’s first direct digital panoramic

imaging unit and pioneering all-in-one

software concept that allowed dental

professionals to access all important

information from one user interface.

“The Planmeca Dimaxis all-in-one

software concept was a groundbreaking

and bold innovation of its time and was

launched long before the term ‘software

ecosystem’ became a buzzword. It

paved the way for many new ideas that

would further improve the daily dental

workflow,” explained Mr Kyöstilä.

Currently, all Planmeca’s dental

equipment offer network connectivity –

in fact, they have done so for more than

a decade already.

The company started immediately

building its global distribution network,

which today consists of over 760

distributors across 120 countries.

“We’ve had a global approach from day

one. Planmeca has never believed in

geographical limits − we have been

ready to travel anywhere in the world

where there are potential customers.

Building an active sales network,

founding local companies to support

the sales staff and staying close to our

customers have been crucial elements

of our success,” he remarked.


In 1975, Mr Kyöstilä finally had the

means to hire his first engineer, which

meant that the company could move to

developing more demanding products


Dental Profile



Next year will mark another milestone in

Planmeca’s history – the 50 th anniversary

of Plandent, a one-stop dental supply

company that Mr Kyöstilä founded in

1972 to provide dental professionals with

all the services, equipment and materials

they need. The Plandent Division

operates in a dozen countries and is one

of the leading dental suppliers in Europe.

But the company group’s expansion did

not stop there.

In 1987, Mr Kyöstilä branched out

into medical technology by founding

Planmed, a company dedicated to

mammography and orthopaedic imaging

equipment. Today, Planmeca Group is

an industry leader consisting of several

successful healthcare technology


What started as a small-scale business

now has a turnover of €764 million,

nearly 2,900 employees, and six

hectares of company premises in Helsink

– where dental professionals from all

over the world are always welcome to

share their insights and ideas.

“Both 2D and 3D imaging systems

became major growth engines for the

company. Focusing on developing

pioneering imaging technology also

allowed us to expand our playing field

outside the dental clinic,” explained Mr


For example, Planmeca’s unique cone

beam computed tomography (CBCT)

technology has been incorporated into

Planmed’s extremity scanner, a solution

used for veterinary 3D imaging too.

With the same groundbreaking imaging

technology used throughout different

product lines, Planmeca Group’s mission

is to bring the best image quality to all

healthcare professionals − from dental

clinics and hospitals to veterinary clinics.

Mr Kyöstilä, commented: “I am extremely

proud of our algorithm expertise.

We have already managed to lower

patient doses considerably and cancel

the effects of patient movement. We

continue to work tirelessly to keep

introducing new innovative algorithms

that will further improve image quality

and help provide the best basis for


Alongside its dental innovations, the

company continues to expand its medical

product portfolio, with a new full-body

CBCT scanner and a ventilator that are

currently under development.



It has taken half a century of

determination, perseverance, strong work

ethic as well as constant innovation to

build today’s Planmeca.

“Of course, not every day has been

smooth sailing. In times of recession

and in otherwise difficult times, we have

worked harder than ever, trying to sell our

solutions to customers in every corner of

the world – and continuing to bring the

latest technology into dental products.

Low technology has never been of any

interest to us,” admitted Mr Kyöstilä.

In fact, prior to the pandemic, thousands

of dental professionals visited

Planmeca’s headquarters every year.

Mr Kyöstilä, shared: “It’s a great way to

receive customer feedback in addition

to trade fairs and congresses. I have

always loved meeting our customers in

person − it has really been the spice of

my working career.”


The digitalisation of dentistry started in

the late 1990s and continued to evolve

rapidly in the early 2000s.

Hence, Planmeca’s early investment

in imaging and software development

began to pay off.



Dental Profile

Despite the company’s global success,

Mr Kyöstilä aims to keep the company’s

production in Finland and preserve the

agility, efficiency, low hierarchy and

entrepreneurial spirit of the company’s

early days.

“I have always believed in the Finnish

know-how and education. I also believe

that it is better to listen than to be

heard. Valuing the expertise of my

staff and hiring the best specialists in

each field are the secrets to building a

successful company,” he shared.

In fact, Finnish design has always been

close to Mr Kyöstilä’s heart, which can

be seen throughout the company’s

product lines.

“Timeless and recognisable design is

one of our key competitive advantages.

Design is so much more than just

product surfaces – it is the outcome of

having deep understanding of clinical

workflows and needs. Unlike in many

other companies, we have an entire

team of in-house industrial designers

who are involved in each stage of the

product development process,” he noted.


With 50 years of experience, Mr Kyöstilä

definitely knows a thing or two about


“You need to see further ahead than your

competition and listen intently to what

your customers are saying. You have to

stay alert to even the tiniest of signals

and be prepared to change your course

accordingly,” he shared.

He is happy that today, unlike in his youth,

entrepreneurship is seen in a positive

light and young people are encouraged to

start their own business.

However, he reminds that there are

no shortcuts to success: “Quality is

everything, and you should never head

to the market with an unfinished product.

One successful product will often help

you come up with new ones.”


Instead of sentimentalising the past, Mr

Kyöstilä prefers to focus on the future.

This means fearlessly expanding into

new territories and staying ahead of

technology trends.

For instance, providing orthodontic

treatment solutions through a new

company called PlanSmile is in the

future plans.

“We continue to deepen our knowledge,

expertise and involvement in different

specialty areas, such as orthodontics,

medical imaging and new 3D

applications. This will allow us to explore

new technological possibilities and

business opportunities,” he shared.

Despite the constant advances in

imaging technology and major medical

projects currently underway in the

company, Planmeca does not forget

about the product that started its

success − a dentist’s most important

working tool – the dental unit.

The company’s research and

development teams are working hard to

come up with new ways to introduce the

latest technologies and upgrades into

dental units to make the daily workflow

the smoothest it can be.

For Mr Kyöstilä, Planmeca is a way of life,

and meeting satisfied customers means

that the company has succeeded in

its primary goal: providing better care

through innovation.

He concluded: “I am grateful to

have been able to work with a highly

professional staff and to have been

surrounded by dental professionals that

I value so greatly. I want to continue to

stay close to my customers and staff. I

want to hear both the negative and the

positive. That is the only way to stay in

the game.” DA

Achieving predictable results

with Anthogyr Axiom Short


Due to bone resorption secondary to tooth extraction, clinicians

commonly perform maxillary sinus lift procedure to restore missing

upper first molar with an implant, especially if the site is left untreated

for a long time. But an alternative and more conservative treatment

approach using a “short and fat” implant from Anthogyr is able to reduce

surgical downtime and risk of complications.

By Dr Sebrina Abdul Malik

A 43-year-old healthy male patient had his

upper left first molar (tooth 26) extracted

three years ago due to a failed root canal

treatment. He is a regular patient in the

dental office, a non-smoker and has good oral


A panoramic radiograph revealed moderate

bone resorption at the edentulous site of

tooth 26 with a low scalloped-shape maxillary

sinus floor (Fig. 1).

The patient had a prior consultation with

another dentist and was recommended to

undergo a maxillary sinus lift procedure to

restore his missing tooth 26 with a dental

implant. But he was concerned about

the complications of the aforementioned

To verify the implant position, a postoperative

radiograph was taken showing that

the apex of the implant sits right below the

maxillary sinus floor (Fig. 3).

An advantageous surgical goal, bicortical

stabilisation was achieved effectively. This

phenomenon can sometimes be difficult to

attain as it occurs when a surgeon engages

more than a single cortical plate when placing

a dental implant.

Typically, this is done with the cortical bone

of the base of the mandible; or the floor of the

maxillary sinus or nasal cavity; and the crestal

cortical bone of the edentulous ridge.

Three months later (Fig. 4), a closed tray

impression technique was carried out (Figs.

5-6). The delivery of a screw-retained zirconia

crown was successful (Figs. 7-8).

Periapical and panoramic radiographs were

taken to verify the fully seated restoration

(Figs. 9-10).


This case delivered a high-quality dental

implant and crown treatment without the

need for more surgical downtime while

reducing the risks of complication that comes

with maxillary sinus lift procedure by using

a “short and fat” dental implant. Anthogyr is

one of the few implant systems that supply

short dental implants. DA

Clinical Feature

Anterior implant aesthetics

A variety of factors have to be considered when performing implant

restorations on the anterior maxillary region given its high aesthetic

demands. Dr Kuoching Chen (Taiwan) shares three cases to discuss novel

techniques addressing the challenges of anterior implant placement.

By Dr Kuoching Chen


A 50-year-old male patient with fair oral

hygiene was presented with a fracture on

tooth 11 which was associated with mobility,

swelling and pain.

Clinical and radiographic examination

revealed that the fracture affected the

palatal-cervical to facial-crestal region of

the offending tooth (Fig. 1). Fistula at the

periapical region of the facial gingiva was also

noted (Fig. 2).

Treatment procedure

The treatment plan included extraction of

tooth 11 followed by an immediate implant

placement. The patient’s extracted tooth will

be used as a temporary crown to maintain

aesthetics and papilla height.

Atraumatic extraction of tooth 11 was

performed using a periotome and elevator.

The socket was flushed with saline and the

granulation tissue was removed (Fig. 3).

Atraumatic implantation was done without flap

elevation and the gap was filled with Endobon

and freeze-dried bone allograft (FDBA).

Clinical Feature

Osteotomy procedure leans against the

palatal gingiva so the implant can be placed

slightly palatal to ensure sufficient buccal


The implant was placed 4mm below the

gingiva margin at the palatal side or 3mm

below the gingiva of the adjacent teeth (Fig.

4). Gingihue abutment was used to ensure

that the gingival space is maintained and the

emergence profile is good.

To use the crown of the extracted tooth as a

temporary restoration (Fig. 5), the crown was

hollowed-out to create space for cementation

of temporary abutment (Fig. 6). After the tryin,

the internal surface was etched (Fig. 7).

Resin bonding procedure was done and

temporary abutment was fixed to the crown

using flowable composite (Fig. 8). The gaps

were filled with more resin, rounded out and

polished well (Fig. 9). The occlusion was then

adjusted 0.55mm from the contact surface.

Additionally, the cervical outline was shaped

and the surface of composite was polished

(Fig. 10). Once done, the provisional crown

was delivered to the patient’s mouth (Fig. 11)

and periapical radiograph of post-implant

placement was taken to confirm its position

(Fig. 12).

After four and a half months, the patient

came back for the final impression (Fig. 13).

The temporary abutment and crown were

removed revealing symmetrical facial outline

papilla (Fig. 15).

In delivering the final restoration, the

abutment was placed with positional jig to

ensure accurate placement (Fig. 16). Then, a

gold-tite screw was used for the placement

of gingihue abutment with porcelain core

(Fig. 17).

Finally, the E-Max crown was issued (Fig.

18). Post-treatment photo (Fig. 19) was taken

as well as a periapical radiograph to ensure

proper position of the abutment to the

implant (Fig. 20).

After seven months, patient came back for

recall presenting a satisfactory shape of

papilla (Fig. 21). Post-operative radiograph

was taken, revealing the occurrence of

interdental bone remodelling (Fig. 22).


There is not much difference between the

use of resin tooth and natural tooth as

temporary crown. But it is easier to use the

latter to maintain gingiva type and preserve

dental papilla.


A 35-year-old female patient came with a

request to redo the crowns on her upper

anterior incisors (Figs. 23-25).

The crowns from teeth 12, 11, 21, 22 were illfitting

(Fig. 26). The cervical margin on teeth

21 and 22 showed black tooth structure, and

the porcelain-fused-metal (PFM) crowns

revealed discrepancy in length. Teeth 12, 21,

and 22 are root canal treated with metal post

and cores for more than 15 years. Gingival

margin inflammation with exudate was noted

on tooth 11.

The rest of the teeth are restorable except for

tooth 21, which already had a short clinical

crown with not enough tooth structure

for ferrule. Thus, extraction and implant

placement were suggested.

Treatment procedure

The treatment plan included removal of

old crowns and fabrication of temporary

crowns for teeth 12, 11, 22; and atraumatic

extraction on tooth 21 with immediate implant


After confirming the marginal bone depth

(Fig. 27), atraumatic one-stage implant was

done with placement of healing abutment

(Fig. 28). Post-operative radiograph was

taken to confirm the implant position (Fig. 29).

Subsequently, temporary restoration was

done and anchored to adjacent temporary

crowns with resin (Fig. 30).

After five months, the final restoration was

fabricated and issued. The abutment was

placed with positional jig to ensure accurate

placement (Figs. 31-32). Then, the zirconia

abutment was issued (Fig. 33) followed by the

delivery of the crowns on the affected teeth

(Fig. 34).

Follow ups were done after three, four, and

seven years; and post-operative intraoral

photos and periapical radiographs were taken

(Figs. 35-40).


Immediate implant treatment with healing

abutment placed reduces the need to have

another incision done during the uncovering



A 45-year-old male patient had an immediate

Effectively remove

stains and biofilm

with Mectron

COMBI touch

By Prof Gianna Maria Nardi

Mectron COMBI touch

combines a multifunctional

piezoelectric scaler and a jet

polisher in a single device

designed for complete dental

prophylaxis. To achieve

excellent results, this article

discusses the operating

procedure of this device

and how air-polishing can

be reliable, effective and

efficient in the mechanical

removal of bacterial biofilm.


User Report

Mectron COMBI touch

Air-polishing can be used on healthy

patients as an alternative to the use of

curettes, scalers or abrasive paste to

remove stains caused by tea, coffee,

red wine, tobacco or other staining


Since the diseases of the oral cavity

with the greatest epidemiological

significance (caries, gingivitis and

periodontitis) are induced by bacterial

biofilms, mechanical control of bacterial

biofilms is fundamentally important in

the prevention and management of

these diseases.

Air-polishing has been found to be

effective in removing biofilms from

above and below the gums and acquired

dyschromia (Europerio 2012, Vienna).


The air-polishing systems use

compressed air, water and various

types of powder with different particle

sizes, specifically designed for different

treatments, to emit a well-controlled jet,

which sprays particles at the surfaces of

the teeth (Barnes et al., 2004).

The abrasive flow therefore consists

of water, compressed air and specific

powders with a controlled particle size

(Black R. Technique for non-mechanical

preparation of cavities and prophylaxis.

J Am Dent Assoc 1945; 32:955-965).

Currently available on the market, there

are numerous devices with an air/water

jet for preparing cavities, polishing tooth

surfaces and eliminating extrinsic stains

in patients that have trouble maintaining

adequate oral hygiene (Kozlovsky et al.,

1989; Horning et al., 1987).

In addition, the shape and design

of the spray nozzle are important

characteristics that may influence the

abrasive properties of the powders


In fact, minor changes in the size of

the nozzle, such as the diameter of

the opening or the length of the tube

or its curvature may cause significant

changes to the efficacy of the

instrument (Momber A, 2008).

This factor underlines the importance

and responsibility of having an indepth

knowledge of the instrumental

technique used on any type of tooth or

root surface.

To determine how to treat each specific

case, the operator may be faced with

the challenge of excess deposits which

require removal.

In such cases, the more difficult

treatment areas will certainly require a

more thorough and lengthy treatment. It

is therefore important to avoid directing

the jet directly at the edge of the gums,

on the necks of exposed teeth and the



Mectron COMBI touch combines, in

a single device, a multifunctional

piezoelectric scaler and a jet polisher,

designed for a complete dental

prophylaxis, above and below the gums.

The polisher supports the use of two

types of powder according to the type

of treatment to be performed: sodium

bicarbonate powder for supragingival

prophylaxis, and glycine-based powder

for subgingival treatment.

The operating principle of the polisher is

based on the mechanical action obtained

from a jet of crystals in various kinds

accelerated by a compressed airflow. The

kinetic energy applied to the particles is

dissipated almost completely when they

strike the enamel surface, producing a

gentle but effective cleaning action.

The action is completed by a water jet,

which, using the pressure drop created

around the nozzle, is arranged in the form

of a bell around the main flow. Thus, it

produces a dual effect: it largely prevents

the cloud of powder from bouncing and

being expelled; and continually washes

the treated area by dissolving the powder.


The COMBI touch device operates at a

working water pressure of one to six bars

and an input air pressure of between four

to eight bars (“Prophy” function = 3.5 bars;

“Perio” function = 2.7 bars). The direct jet

should not be directed at the gums while

the peripheral jet can be used close to the

gingival margin.

COMBI touch air-polishing produces

excellent hygienic and cosmetic results: it

removes even the most stubborn extrinsic

stains quickly, gently and under conditions

of absolute safety.

The enamel surfaces of the teeth remain

intact and shiny. When used below the

gums, it removes bacterial biofilms from

the periodontal and peri-implant pockets.

The abrasive nature of the jet of powder is

directly proportional to the selected level

of irrigation. In this way, by increasing

the level of irrigation at the end of the

treatment, the teeth above the gums can

also be cleaned.

Mectron recommends exclusive use of

their prophylaxis powder and glycine

powder. The manufacturer declines all

liability and the guarantee becomes

null and void if non-original Mectron

powders are used, in that they could

irreparably damage the spray nozzles

and/or handpiece of the polisher, thus

jeopardising the operation and creating

a risk of injury to the patient.

With the supra- and subgingival

technique, the spray nozzle of the

instrument must be kept constantly

rotating at a distance of 4-5mm from

the tooth surface for about five seconds

per tooth.

For maintenance treatment, the

instrument should be held at an angle

of incidence of between 30° and 60°

between the powder jet and the axis

of the tooth; the correct angle of

the handpiece is essential to avoid

damaging the soft tissues and to reduce

the quantity of aerosol emitted (Barnes,

1991; Worrall et al., 1987).

The Mectron COMBI touch offers three

spray nozzles at different angles to allow

procedures according to every clinical


A. The 120° spray nozzle for use

outside the periodontal pocket

(Figs. 1-2):

The use of the spray nozzle at this angle

provides an effective deplaquing action,

primarily in cases in which the operator

encounters difficulties due to particular

anatomical structures of the soft tissues

and positioning of teeth or prostheses

that are difficult to reach.

For healthy gum tissue and particularly

stubborn stains, the use of sodium

bicarbonate powder is recommended.

While in the presence of metal-free

prostheses, implants, exposed root

surfaces and in mouths with a thin

tissue biotype, the glycine powder

should be used.

This spray nozzle is also capable of

deplaquing subgingival surfaces with

glycine powder for periodontal pockets

with a depth of up to 5mm.

B. The 90° spray nozzle for use

outside the periodontal pocket

(Figs. 3-4):

Used for deplaquing the surfaces of the

front teeth using sodium bicarbonate or

glycine powder is recommended, with

the advantage of preserving the soft

tissues of the gums.

It is also used for cleaning the occlusal

surfaces of permanent teeth with

sodium bicarbonate powder or the

occlusal surfaces of deciduous molars

with glycine powder.

Ideal for treating acquired dyschromia,

as in the case of stubborn tobacco

stains, with sodium bicarbonate powder.

C. Periodontal spray nozzle for use

inside the periodontal pocket (Figs.


Ideal for effective detoxification in the

presence of periodontal pockets with

a depth of over 5mm using the sterile,

disposable periodontal subgingival tip,

which enables the inside of the pocket

to be cleaned in a minimally invasive


In addition, its 120° angle enables the

operator to work under more favourable

ergonomic conditions with the correct

supporting points, without applying stress

to the carpal tunnel. The tip does not emit

the jet in the apical direction but orients

it sideways towards the root surface and

the wall of the pocket, preserving the

integrity of the junctional epithelium.

Having determined the clinical indexes,

if a site with a pocket having a depth

of over 5mm is found during the

examination, the periodontal subgingival

tip should be applied to the PERIO spray

nozzle, ensuring that it is fully inserted

so that the two parts must be in contact

with one another.

During the decontamination of the

periodontal pocket with glycine powder,

the tip is to be inserted gently inside

the pocket, against the root surface to

be decontaminated, making extremely

light and regular forward and backward


A time of about five to 10 seconds of

spraying is necessary to satisfactorily

detoxify a periodontal pocket (mesial,

distal, vestibular and lingual surfaces).

Consequently, it will take about 20-40

seconds for the instrument to clean a

single tooth.


The efficacy of sodium bicarbonate

in deplaquing and the elimination of

acquired dyschromia had been known for

some time now, but the true revolution

was the introduction of supra- and

subgingival air-polishing using glycine




The COMBI touch technology, which enables both powders to be

used at the same time due to the ergonomic spray nozzles oriented

at 90° and 120°, enables the operator to obtain an excellent clinical

result, with an advantage in the timing of the procedure much

appreciated by patients.



COMBI touch

The highly sophisticated supra- and subgingival air-polishing

technique enables the operator to perform a complete, effective,

minimally invasive and repeatable clinical procedure without

interfering with the health of the hard and soft tissues of the oral




For the therapy to be successful, the operator must adopt a

personalised tailor-made approach, shared with the patient, to

clinical supra- and subgingival air-polishing practice.

In fact, the skill of the operator is of fundamental importance, who

must be capable to work only after making an accurate diagnosis and

to establish the opportunities for using the subgingival air-polishing

technique. DA

Enhancing quality


By Dr Marie Fluent

Instrument processing is performed to

provide sterile dental instruments for

safe patient care. While the combination

of monitoring methods is intended to

safeguard the process, procedural error

may still occur. Quality assurance measures

recommended by the Centers for Disease

Control ensures instrument sterility as well

as instill a sense of calm and confidence in

the dental team.

The Centers for Disease Control and

Prevention (CDC) Guidelines provide

recommendations for instrument

processing and monitoring the

effectiveness of autoclaves using a

combination of mechanical, chemical,

and biological monitors (spore tests).

Spore tests remain the gold standard for

monitoring the sterilisation process as

it directly kills highly resistant bacterial

spores rather than merely testing

the physical and chemical conditions

necessary for sterilisation.



User Report

Although mechanical and chemical

indicators do not prove sterilisation has

been achieved, they allow the detection

of certain equipment malfunctions and

identify procedural errors.

Thus, it is recommended that sterilisers are

monitored with spore tests at least weekly,

and any load with an implantable device.

She placed the spore test in the

centre of an empty chamber per the

manufacturer’s instructions and mailed

it for processing.

On Thursday, she received “immediate

notification” from the sterilisation

monitoring service that her spore test


Unfortunately, incidents such as this still

exist but some measures can be taken to

prevent such situations.

This article will address quality assurance

measures to ensure instrument sterility

and instil a sense of calm and confidence

as well as a culture of safety to dental

personnel who reprocess instruments.

While the combination of monitoring

methods is intended to provide

safeguards and ultimately ensure

sterility, gaps in quality assurance do

exist as demonstrated in the following

case scenario.


Kim, an experienced dental assistant

was a relatively new employee at a

dental facility. She performed a spore

test early Monday morning on an

autoclave – a different brand from which

she was trained.

Recognising the implications, slight

panic and a series of questions raced

through her mind: “Why did it fail? What

happened to the instruments that have

been processed since the test, and have

they been used for patient care? Could

I identify unused packages, retrieve and

reprocess them? Should the patients

who may be impacted be notified? And,

what should I do next?”

Kim immediately reported this situation

to her infection control coordinator and

the owner/dentist.



In the scenario above, over three days

of patient care had been performed

utilising numerous instrument packages.

There is a possibility that the autoclave

had been malfunctioning for the entire

three days (or more), or that this was an

isolated cycle-failure incident.

Potentially, one or more patients over the

course of the three days, may have been

treated with instrumentation that failed

a spore test.

User Report

The answers to these possibilities are

unknown, and it is evident that a threeday

gap in the biological monitoring

process represents a gap in quality


Before continuing with this scenario,

CDC recommendations for chemical

indicator use will be briefly discussed.


CDC Guidelines recommend various

types of chemical indicators (CI)

including the use of “external” and

“internal” CI stating that a “Type 1

CI be placed on the outside of each

instrument package, unless the internal

CI is visible from the outside.”

The guidelines also address “singleparameter”

and “multi-parameter” CI as

they provide a more reliable indication that

sterilisation conditions have been met.

Yet, there are no specific recommendations

for the use of these specialty indicators

within the guidelines.

The manufacturer’s instructions for use

of the CI will indicate the steriliser type

and cycle in which the CI should be used

– placement within the package, storage,

expiration date, and how to interpret the

exposed CI.

Table 1 provides a list of chemical indicator

types and a brief description.


Type 5 integrating indicators mimic the

response of a biological indicator (BI).

These specialty indicators contain a

steam sensitive chemical that imparts a

physical change, such as movement of

the chemical along a strip or a change of

ink from one colour to another when all

critical parameters of sterilisation have

been met.

They do not guarantee that sterilisation

has occurred, nor do they replace the

need for weekly — or more frequent —

spore tests.

Yet, as integrating indicators allow

detection of certain equipment

malfunctions and aid in identifying

procedural errors; they permit dental

personnel to confidently release dental

instruments before the spore tests are


Note that sterilisation loads containing

implantable devices must be

quarantined until a passed spore test

has been achieved.

Type 5 CIs are intended to be used at

least once per day in every load with or

without implantable device or even in

every pack as the internal indicator.

To use a Type 5 integrating indicator for

each load, the strip should be placed

in the middle of the chamber or within

the densest instrument pack. The load

should be processed according the

steriliser’s instructions for use.

The results may be read immediately

upon sterilisation cycle completion

and it should be interpreted per the

manufacturer’s instructions for use.

If the interpretation does not indicate

a safe or pass, the load may not be

released as these instruments are not

considered safe for patient care.



Kim may have averted much anxiety if



User Report

she had processed a Type 5 CI within

the same cycle as her spore test.

Upon completion, she would have

immediately identified a failed cycle.

As the majority of failed spore tests

are operator related, she would have

followed CDC recommendations

for BI failures, reviewed sterilisation

procedures, and retested the steriliser

using another Type 5 integrating

indicator and additional spore test.

If the subsequent cycle passed the

integrator test, Kim would have mailed

in the spore test for processing.

Most importantly, she would have

had confidence that the processed

instruments subsequently were safe for

patient care.


This situation with the failed spore test

is a true story. As events unfolded, the

infection control coordinator reviewed

the autoclave instructions, and it was

determined that the door of the steriliser

was unlocked during the failed cycle.

Hence, there was not adequate steam

and pressure for sterility to occur.

A Type 5 CI with an additional BI

was then run through an additional

sterilisation cycle.

The integrating indicator passed, the

autoclave was placed back into service,

and the owner/dentist deemed it was

not necessary to notify patients. The

repeat BI test was negative for growth

of spores, as anticipated.

Behind the Scenes

Polishing of dental

hybrid materials

While the use of hybrid materials has recently gained popularity

in fabricating indirect restorations, polishing such material

pushes conventional polishing agents to their limits. For this

reason, a technical and scientific analysis depicts how Renfert

Polish hybrid materials addresses this concern to achieve fast,

economical polishing with optimal outcomes.

By Dr Frank Weber and MDT Manfred Tauber

Uniting the positive properties of two distinct

materials, hybrids like CAD/CAM materials

and filled veneer composites are increasingly

used to fabricate indirect restorations (Fig. 1).

This combination of ceramics and polymers

exhibits a high load-bearing capacity with

improved abrasion behaviour while reducing

brittleness to easily process the restorations.

But polishing pushes conventional polishing

agents to their limits because each of the two

materials has distinct requirements.

Another complicating factor is the uneven

material ratio — high ceramic, low composite

content — which varies from supplier to

supplier. Thus, much more preparation and

polishing work was previously required to

achieve a satisfactory gloss level albeit with

limited results.

Renfert Polish hybrid materials comprises a

specialised diamond polishing paste which

does precise justice to the unique needs of

these hybrid materials (Fig. 2). The paste is

designed to account for both the complex

wetting behaviour as well as the different

degrees of hardness of the two material


Why is it so important to polish the

surface to a high gloss?

In addition to aesthetic aspects, various

authors 1 have demonstrated that the

roughness of a surface correlates with the

gloss within the high-gloss range.

On the other hand, the surface roughness

has a critical mechanical impact on the

antagonist and affects the growth of plaque.

That means achieving a consistently longlasting

high gloss is the most viable indicator

of low roughness and, in turn, reflective of

high-quality work.

For that reason, Renfert develops,

investigates and compares internally as

well as through an external authoritative

institute the roughness and level of gloss as

defined by the gloss units (GU) of the various

materials. This is the only way to achieve

optimal outcomes, with consistently smooth

surfaces even upon closer inspection.

fabrication of indirect restorations

Lubrication with oils and the application of

soft waxes can be used to easily imitate a

visual high gloss on the materials, creating a

short-term appearance, but that cannot be

the objective.

Description of the investigation and

measured data (Development Department,

Renfert GmbH)

For this investigation, at least three uniformly

shaped test specimens each produced from

the respective CAD/CAM block were prepolished

and then polished to a high gloss

according to the operating instructions under

the same conditions.

Subsequently, the test specimens were

measured with a Minolta CM2500d operating

on the basis of an Ulbricht ball. In particular,

the 20° angle required for high-gloss

measurement is not only maintained but

sharpened to 10° and the measured data is

determined in gloss units (GU).

In the investigations with VITA ENAMIC ® , the

highest GU > 120 with the lowest spread of

values was achieved with the Renfert Polish

Three surface measurements were

conducted respectively for each of the seven

hybrid materials on a non-polished sample

and a sample polished to a high gloss with

Renfert Polish hybrid materials.

As examples, the measured data of the

three hybrid materials with disparate surface

structures are presented. The following

examples show the measurement before and

after polishing.

The investigations were carried out using a

MicroProf ® with a CFM confocal microscopic

sensor and a 50 times objective at a

measuring field size of 375x278 μm² (Fig.

4). All measurements were used to analyse

the surface texture according to DIN EN ISO

Press ceramic,


Dental Technician Ömer Gençtürk, owner of

Da Vinci Dental Studio in Antalya, Turkey

Despite the advent of digital processes,

analogue press ceramics remain an

economical method of fabricating dental

restorations today. With VITA AMBRIA,

the new generation of press ceramic,

Mr Ömer Gençtürk (Turkey) successfully

constructed a cosmetic veneer

restoration for four upper incisors of

a young patient in combination with

veneering ceramic, VITA LUMEX AC.

Everyone is talking about CAD/CAM,

which plays an even greater role in

the fabrication of dental restorations.

However, analogue press ceramics are

still used in many laboratories. It remains

an established, economical and efficient

fabrication method.

Until now, a reaction layer with the

investment material could lead to surface

imperfections and fit issues and has been

a challenge. The lithium disilicate that is

used often appears greyish and lifeless,

due to its crystalline structure.

However, that issue is not something

practitioners have to settle for, according

to Dental Technician Mr Ömer Gençtürk,


Behind the Scenes

owner of Da Vinci Dental Studio in

Antalya, Turkey.

He was given the new generation of press

ceramic, VITA AMBRIA, made of zirconiareinforced

lithium disilicate for testing,

in collaboration with Dr Ahmet Emre

Gülerik, a dentist from DentGroup Clinic in

Antalya, Turkey.

In combination with veneering ceramic,

VITA LUMEX AC, Mr Gençtürk achieved

a highly aesthetic result from the first

application and shares his experience

in using VITA AMBRIA in fabricating a

cosmetic veneer restoration.

Many dental technicians are reluctant

to implement new materials in their

laboratory. What was your experience

with VITA AMBRIA press ceramic?

There are always concerns, especially if

processes have generally been working

well in the past. In the end, curiosity

prevailed. I wanted to see whether I could

achieve better results by using the VITA

AMBRIA material system.

In fact, I simply followed the instructions

for use and there was no learning curve.

During the first usage, I could see that

VITA AMBRIA delivers what it promises.

So, there is no need for concern when

shifting to this new product.

When working together with the

dental practice, how important is

absolute shade accuracy of the

material to the VITA shade standards?

The VITA shade guides are a standard

worldwide. The material also has to

precisely match the corresponding shade

tabs. If I determine an A3.5 on the patient,

there should also be an A3.5 in the press

and veneering ceramic.

This is the only way I can reproduce the

shade appropriate for the patient and be

confident that my clients are satisfied

with my work. VITA AMBRIA, as the

shading element, proved to be true to the

shade in this patient’s case.

Removing the mould is always a tense

moment. What was your experience

with this process?

Removing the mould is the moment of

truth because I have never tried VITA

AMBRIA before. And, of course, it is also

the moment when you hope that the

ceramic will come out of the investment

material without any damage. The thin

Behind the Scenes

Use of a 3D

printer in a fully

digital workflow

A fully digital workflow boosts accuracy,

flexibility and efficiency. But how does a 3D

printer contribute to making this possible?

The following clinical case discusses the role

of a 3D printer in a digital workflow.

A fully digital workflow has been the

subject of discussion and debate within

the dental industry for years. Today,

thanks to the development of cuttingedge

technologies, it is finally possible to

approach this working methodology to

allow the clinician, dental technician and

most importantly, the patient, to rely on a

predictable treatment with reduced time

and costs.

Within this workflow, the role of the

3D printer assumes considerable

importance, both for the production of

classic artefacts such as models, gingiva,

surgical guides and temporary elements.

It also offers the option of adopting

alternative approaches and creating, for

example, aesthetic and functional waxups.

Behind the Scenes

On one hand, 3D printer allows the

dental technician and clinician to match

what was digitally designed to what was

created instantly. On the other hand,

it helps the patient to have a clearer

understanding of the treatment.

This process allows the professional

to adopt an approach considering not

only the clinical and functional side but

also the psychological impact of the

treatment, particularly in the case of

rehabilitation of total edentulism.

The following clinical case fits precisely

within this context:

Greater control and improved clinical

predictability — Invisalign G8 with

SmartForce Aligner Activation is the newest

series of biomechanical innovations for

Invisalign treatment informed by tooth

movements from millions of patients treated

with Invisalign clear aligners.

Invisalign G8 is part of Align’s ongoing

commitment to further enhance

Invisalign as a force driven system.

It focuses on improving deep bite,

crowding and cross bite cases. These

cases are improved by adding the

Aligner Activation feature to aid in

anterior intrusion for deep bite cases

and posterior arch expansion for crowding

and cross bite cases.

SmartForce features are even smarter

SmartForce Aligner Activation ensures

areas on the aligner surfaces are contoured

to apply forces to the tooth in the proper


Throughout every stage of treatment,

the location, direction and intensity of

the force work in harmony to create

optimal force system unique to the

patient (Fig. 1).

Predictable deep bite correction

Invisalign G8 improves clinical

predictability of incisor intrusion in deep

bite cases by up to two times 1 . Intrusion

force levels are optimised for each

tooth, and the precision bite ramps are

clinically proven to improve lower incisor

intrusion by up to 30% 2 (Fig. 2).

Posterior arch expansion in

crowding and crossbite cases

Automatically programmed to apply and

distribute the required force to each

posterior tooth, Invisalign G8 is designed

to deliver more predictable posterior

arch expansion for resolving crowding

and crossbite cases (Fig. 3).

Reduction in the likelihood of

posterior open bite

Invisalign G8 provides more predictable

anterior intrusion, which may reduce

premature anterior contacts – a

common cause of posterior open bite.

Invisalign G8 also controls unwanted

buccal crown torque or tip during

expansion which is another common

cause of posterior open bite (Fig. 4). DA

Compressed air: More than

oil-free, dry and clean

A dental facility cannot operate without

a dependable supply of compressed

air. Whether it be a simple handheld air

nozzles or modern CAD/CAM systems —

oil-free, dry and clean compressed air is

an essential ingredient in the success of

a dental laboratory.

But in the advent of digital technologies,

which includes milling and grinding

machines in the dental laboratories,

these simple requirements to the

compressed air are not sufficient


Modern CAD/CAM milling and grinding

machines require a stable supply of

compressed air to function optimally. The

following tackles a solution to achieve

consistent, high-quality compressed air in a

dental facility.

The present manufacturers of CAD/

CAM systems frequently ask for a clearly

defined quality of compressed air. Most

of the time, they look for the 1-4-2

classes of quality.

These classes refer to the ISO 8573-

1:2010 for compressed air — the

international norm that defines the

purity classes and regulates how much

water, oil and particles are allowed

to remain in the compressed air after


These three characteristics are the


Class 1 particles

Maximum particle count per m 3 of a

particle size with d [µm]*)

0.1 < d ≤ 0.5 ≤ 20,000

0.5 < d ≤ 1.0 ≤ 400

1.0 < d ≤ 5.0 ≤ 10

Class 4 water

Pressure dew point, in °C

≤ +3 °C

A CAD/CAM system needs a constant air quality and a pressure of seven bar.

For the remain equipment in the dental laboratory it will be recommended to reduce the pressure

to 5,5 bar. This helps to reduce leakages, drop energy costs and save environment.

A nightly separation of the remain laboratory from the air supply enhances these effects



In Depth With

Existing compressed air stations can be equipped with a dryer and filters to purify air required for milling machines quality

A modern compact compressed air station like

the Aircenter is a profound solution for dental


Class 2 oil

Total oil concentration (liquid, aerosol +

gaseous) [mg/m3]*)

≤ 0.1

*) At reference conditions 20°C, 1 bar (a),

0% humidity

Modern CAD/CAM milling and grinding

machines represent a significant

investment, which needs to be amortised

as swiftly as possible. In order to achieve

this, the systems should run round the

clock, ideally even at weekends.

But to function seamlessly, this

equipment requires a stable supply of

quality compressed air at a minimum

pressure of seven bar.

If the requirement regarding pressure

and air flow is fulfilled, the existing

compressed air system can be equipped

with filters and a refrigeration dryer

without loss of compressed air output

in the form of purge air. This allows

compressed air quality to be adjusted

according to the new requirement.

However, if there is a need for a

completely new compressed air supply,

screw technology is the best solution,

economically and technically.

Designed for 24/7 operation, a screw

compressor along with proper air

treatment equipment is suitable to

operate in a laboratory which has a

ready-to-use milling machine or has

intention to use one in the future.

In a dental facility using a CAD/CAM

system, the demand for compressed air

enlarges dramatically and the working

hours of the compressor increase by 10

to 15 times in comparison to conventional

dental labs. This mode of operation is

best handled by compressors based on

screw technology.

When a new compressor is to be installed,

it is also important to consider the

compressed air supply of the remaining

equipment in the laboratory. DA
