DENTAL KIEFER

Since 1984 engaged in innovation, development and tuition of dental

technology.

We offer a cohesive system of precisely adapted components of our highest

quality from the impression tray to the face bow transfer, as well as from 3

different ways for a high precision dental model to the anatomically “bio-precise”

articulation … and much more.

The following information will give you an overview about the diversity of our

products.

The different themes are clearly delineated to facilitate access by clicking on the

desired subject.

For further in-depth studies of the technologies and applications of our products

we organize regularly courses at our fully equipped laboratory in the northern of

the Alsace, France.

Useful tips for the preparation

We had an idea how the dental preparation might be facilitated-but

unfortunately, somebody else has been decidedly faster.

In the interest to spread knowledge we feel, nevertheless, compelled to

acquaint all possible user with this idea.

Thanking the originators „Brasseler-Komet“ for providing this documentation

to us, we append hereunder some explanations about their technology.

The work on the

patient is

encumbered with

many problems. To

warrant the best

results and to

facilitate our work, it

is the more important

to select the most

suitable products.


The polished guiding pin offers a reliable support during the preparation,

cleanses the part below the preparation‘s border to permit a proper

impression taking and, at the same time, permits to dilate the root of the

tooth.

As actually already requested in 1977 by Professor Martingnoni, Rom, Italy.


And that leads us the problem

of the precise impression

which is considerably

facilitated by the use of this

diamond studded guiding pin.

Which, under normal

circumstances, obviates the

need for coagulation

measures.


High quality plastics molding materials:

one of the bases of our inventions!

stable, disinfectable ( up to 80 ° C ) reusable


Twimptray

Can be used with most techniques and

materials

Opened impression tray for upper and lower

impression at one time and in occlusion

If needed, the palatal can

be fixed

occlusal contacts

Beautiful antagonist impression

For its protection, the impression is

hanged on our shipping box


Twinvacuation

innovative evacuation – and – pression technique

Our tray is hollowed out. 2 holes at the inner

sides ( molar area) are connected with the

green tube.

Under the handle, a conical injection channel

allows to inject the cleaning liquids, correcting

material, a.s.o.

Specially designed for the

most difficult cases:

Its tube is fixed at the

absorber of the dentists unit


DENTAL KIEFER

TWIN JECTION


Corrective material only

on the prepared stumps

…..

Common mistakes

…. is the reason that the stumps also by using a

precision model will be lower than the remaining

teeth. The result: --► wrong articulation !

Crowns and bridges will be to high in patients

mouth = doctor has to grind !!

Pre-impression taking after the preparation

contributes to compression of the corrective

materials and results in too small stumps.


„Drayh“- Box

All parts of the system

are reusable and can

be sterilized !


Each size is available

in short or long

version =

offering more comfort

for the patient and

saving material

4 sizes – by colourcode

Size 1 – red

Size 2 – blue

size 3 – orange

just one impression

Twin Jection offers precision

impression for both sides at

the same time !

Technical characteristics

the “Wilson” curve

With its sophisticated

design and appropriate

materials the

impression tray is

sturdier than most

metal ones.

The height for two

impression is equal to

other impression trays

for only one !

“Spee`sche” curve and closing angle were considered. The sturdy bottom

saves material and enhances stability. Different thickness in front and

backside!


Palate impression

The reusable palate bit is

simply to be put on the

tray – it locks on !

Routinely there is no need for

a palate bit

= no risk of gagging

Where it is, however,

indicated – e.g.

Combinations or Totals


All impression trays‘ sizes are

also available in transparent

material

- i.e. ideal to determine the size

according to the patient‘s

physical requirements.

reusable elastic space holders may

be cut to required length

= saving corrective material.

Single phase

e.g. polyether

Twin Jection

Twin Jection allows using practically

any material and technique

Or corrective impression taking by external dynamic injection

Double mix


Theory

Hydro, single phase, double mix, or corrective impression

Common mistakes at the corrective impression:

2. Pre-impression taking after the preparation

3. Insufficient clearance = putty touches the gum. During the corrective

impression the putty is pushed against the stump.

If around the stump there is no clearance, how can the corrective

material flow and reproduce the exact image of the preparation ?


Twin Jection:

Technique 1

The injection channel lays

above the teeth occlusion

Theory

We recommend pre-impression prior to the preparation –

providing the space for the corrective material and obviate

cutting later on.

Plus, the putty has enough time to harden.


Twin Jection:

Technique 2

Theory

At the corrective impression with Twin Jection the material

flows under pressure from occlusal along the prepared walls

in the direction of sulcus. Impurities, such as blood, saliva and

air bubbles are pushed out through the elastic gum. As the

injection pistol with the corrective material will immediately be

withdrawn after the injection, the produced pressure will fast

dissipate without any deformation or overpressure of the

impression.


Techniques

4. Also the counter part!

1. Putting the space holder

2. Apply some putty

and allow it to

harden

3. Fill the tray until the rim


The counter


The technique

Following the hardening of

the first impression

– the elastic space holder

will be retracted.


The technique

Opening the injection

channel between teeth

center and main channel


The corrective impression

The same to the counter side

At first we fill the main channel

Applying corrective material

onto the impression –

preparation side


The corrective impression

After the prepared impression has been

put into the patient`s mouth

– Attention ! – the mouth should not be

opened unduly to prevent spasm of the

jaw muscles; which, in turn, might

render insertion of the impression tray

more difficult.

Always insert OK (upper) first then the

UK (lower ).Subsequently the patient

should exert his bite without undue

force.

The unique advantage of our technology relying on external pressure

results in a dynamic flow of the corrective material expelling blood, saliva

and air bubbles through the elastic gum.


The result

Equal distribution of the corrective material – to prevent

differing heights of the stumps in the model.

Quite obvious :

The even

distribution of the

corrective material

and is connection

to the main

channel

Examples for its use :

Holed end comes useful in

preparing single crowns and

temporaries


Iron rules for successful impressions with

„Twin Jection“

• Selection of the optimal impression tray size is mandatory for the corrective

material – channel must be exactly in the middle of the occlusion

• Pre – impression before the preparation

• Pre – impression to start invariably on the preparation`s side observing

strictly proper alignment – then to close counter

• At the pre – impression it is imperative to leave enough putty around the

stump – approx. 3-4 millimeters and that the same thickness is also above

the preparation`s borders adjoining the gum.

• With more putty applied in the pre – impression phase it may provide a layer

around the impression tray`s border – thus enhancing more stability.

• For single crowns just a hole to the main channel is punched with our

special tool – for several crowns or bridges a linear opening suffices.

• Corrective impression always first to be put in upper jaw – even though the

lower has been prepared. The patient will find the right position with the

lower invariably.

• Putty should preferentially have hard shore quality

• Correcting material should have medium viscosity


The result :

An even distribution

of the corrective

material across the

whole impression.

The only way to

avoid differing

heights of stone

model dies.

Single crowns

Pre – impression before

preparation – followed by opening

the channel using the round hole


Bridge impression

Bridge impression :

- Pre – impression before preparation

- Linear cutting to main channel

That way one recognizes the mounting

angle of the root. A prerequisite for is

transfer to the replacement tooth


Inlay impression

Considerably more

economical than

„Kofferdam“ – the rubber

band for sports.

For the pre – impression

we cut a piece of that

rubber foil.

The transparent impression tray will

be marked where the inlay

preparation will be effected


Inlay impression

The rubber piece is located in

the desired area to create the

occlusal space for the

correcting material.

For the corrective impression we remove

the holder. The gap to the remaining teeth

will ensure an adequate thickness of the

corrective material around the area of

preparation.


The result:

An even distribution of the

corrective material assures

a perfect occlusion.

Partial work


A correct bite occurs

automatically – an

ideal basis for a

functional

impression.

Impression for totals

Since it is a closed mouth

impression „Twin jection“

is ideal for total protetics

and comfortable for the

patient.

Again a fast and

distortion - free face bow

„speedy transfer“


Mounting of the upper

Totals

Without any further ado the position of the teeth in

the articulator was the same as in the mouth.

Vertical adaptability of

our „WK light“ proves is

worth.

Old against new.

The former dentist

was of the opinion

that a better basis

prosthetics were

unattainable.


Temporaries with „Twin jection“

A pre – impression with putty will be made

prior to the preparation. The special tool

again serves to open the channel

The external dynamic injection technology serves

ideally also for the production of temporaries

Modern self – mixing resins are used – those

do not react with the „Twin jection“ tray

material.


Temporaries with „Twin Jection“

The result

If for instance, a temporary with an

intermediate part should be made, an

artificial tooth takes its place in

patient`s mouth to permit checking of

the occlusion. Subsequently we take a

pre – impression.

The temporary in the impression – to remove

it one may cut the putty.


Face bow transfer

Silifix „W“

A metal tray at room temperature

reduces silicon to around 18 ° C. But it

had been taken at 36 ° C !!! Therefore

we use „Silifix“ W – wax based – and

heat it to 36 ° C. At this temperature it

becomes soft and , nevertheless, lead

dead. I.e. there is no danger of

deformation for the impression material

or a recoil effect to it.


Theory

Marking the envisaged

Pilot pins in the „pilot

plate“

Each segment separated by

sawcut is fixed with at least 2

pins. The pins are placed at

random somewhere between the

envisaged sawcuts. Larger

segments must be cut to

compensate the stone expansion.

For hardening the impression including stone model

directly be placed in 36 ° C warm water.

Why ?

Temperature

continuously

adjustable

from 0 ° C –

40 ° C.

Again the imression is heated to mouth temperature,

we smoothen the stone surface and reinforce

borders.

Once the stone has hardened it is not allowed any

more to get in contact with water or steam. But its

hardening in the water bath leads to much higher

material quality!

The articulation

The pins looking out on the

To avoid gypsum to enter

the pin holes from the

articulation side we offer a

reusable articulation plate.


Preparation of the articulation plate

The articulation side

of the base plate and

the articulation plate

will be sprayed with

„Break Agent“

The 4 stainless

articulation pins long

are inserted –

flattened part towards

Preparation of the articulation plate

The parts are put together and screwed


Preparation of the articulation plate

Several pre – prepared parts are put –

preferentially on „Silifix“ SC – and filled

with „Poly Plus 2000 S“. At the elapse of

approx. one hour the screws will be

loosened, the base plate knocked off

and all be cleaned. That ensures

continuous precision at the articulation.


The face bow transfer

The „Twin Jection“ impression is fixed

and the upper model with it articulation

plate can be mounted

On our articulator „WK light“

we remove the inzisal pin

and - mounting the aluminum

upper part is hanging free

and parallel to the lower.

Now the face bow is fixed –

any face bow can be used –

and stabilized by the

stainless steel supports.

Condylus condome

How does the human condyle work ?

Where is there any precision ?

Should the articulator

imitate „discus

mounting the lower

model – we administer

the soft 2 mm „condylus

condome“

– this is the only way to

imitate anatomical

movements!


Condylus compression test

As soon as the patient exerts

a pressure on that foil – the

„human discus articularis“ is

compressed being pulled by

the muscles. This has an

important influence to the

occlusion and articulation.

For testing the compression of the

human discus articularis we take a

0,15 mm strong foil
