DENTAL UPDATES<br />

ZimVie introduces two next-generation dental solutions in the US<br />

ZimVie, a global life sciences company<br />

in the dental and spine markets, has<br />

announced the joint launch of the new,<br />

FDA-cleared T3 PRO Tapered Implant and<br />

Encode Emergence Healing Abutment in<br />

the US.<br />

The T3 PRO is the newest addition to<br />

ZimVie’s family of dental implants and<br />

builds on the proven solutions of the T3<br />

Tapered Implant. The Encode Emergence<br />

Healing Abutment builds upon ZimVie’s<br />

3-in-1 Encode Impression System which<br />

provides clear intraoral scans and<br />

aesthetics, and is designed for patient<br />

comfort and healing.<br />

Both the T3 PRO and the Encode<br />

Emergence reflect significant innovation<br />

to ZimVie’s previous products and promise<br />

an optimised implant experience for both<br />

dentists and patients. ZimVie will begin<br />

commercial rollout of these solutions<br />

in the US, with an intention to expand to<br />

additional countries pending necessary<br />

regulatory approvals.<br />

“We are excited to launch the next<br />

evolution in our T3 family of implants<br />

and Encode impression system, which<br />

has been used in more than two million<br />

implant restoration procedures to date,”<br />

said Indraneel Kanaglekar, senior vicepresident<br />

and president of ZimVie <strong>Dental</strong>.<br />

“ZimVie is committed to providing innovative<br />

treatment options to improve patient care<br />

while partnering with dental professionals<br />

globally to advance dental technology and<br />

end-to-end workflow solutions.” ■<br />

US study analysing tooth survival after root canal reveals the factors impacting<br />

longevity of treated teeth<br />

Teeth survive about 11 years after a root canal,<br />

according to new research from Regenstrief<br />

Institute and Indiana University School of<br />

Dentistry, US. This study is the first to analyse<br />

records from community dental practices,<br />

where most Americans receive dental care.<br />

“The findings of this study give deeper insight<br />

into the longevity of dental procedures<br />

because it provides real-world data on a wider<br />

range of patients, not just those receiving<br />

care in large health systems or those who<br />

are insured,” said first author Thankam<br />

Thyvalikakath, DMD, MDS, PhD, director of<br />

the Regenstrief-IU School of Dentistry dental<br />

informatics programme. “This information<br />

can be used to inform dental practice, and<br />

help patients and dentists make better care<br />

decisions.”<br />

Root canals are an important treatment<br />

to maintain natural teeth affected by<br />

disease. However, over time, the treated<br />

tooth eventually becomes brittle and dies.<br />

Understanding the outcomes of the procedure<br />

is essential to improving dental treatments.<br />

For this study, the research team gathered<br />

deidentified electronic dental records from<br />

the National <strong>Dental</strong> Practice-Based Research<br />

Network, consisting of 99 small group and<br />

solo dentistry practices from around the<br />

country. The data covered more than 46,000<br />

patients who received root canals.<br />

BREAKING DOWN THE ROOT CANAL<br />

DATA<br />

Data analysis revealed that the median<br />

survival time of a tooth after a root canal<br />

is 11.1 years. However, several factors can<br />

impact that, including follow-up treatments.<br />

•Teeth that receive a root canal, and a<br />

subsequent filling and crown last about<br />

20 years<br />

• Teeth that receive either a filling or a<br />

crown after a root canal last around 11<br />

years<br />

• Teeth that receive no restorative work<br />

after a root canal only last about 6.5 years<br />

There were also wide disparities in longevity<br />

among geographic regions.<br />

• Northeast – 20.5 years<br />

• Midwest – 11.2 years<br />

• Southwest – 11.2 years<br />

• South Atlantic – 9.1 years<br />

• South Central – 9.0 years<br />

• Western – 8.7 years<br />

Insurance status also played a significant<br />

role in tooth survival time.<br />

“This data could also inform dental<br />

insurance coverage by demonstrating the<br />

value of crowns and permanent restoration<br />

options,” said Dr Thyvalikakath. “Oral health<br />

is a public health issue that significantly<br />

affects people’s overall health. Leveraging<br />

dental records can help us better<br />

understand ways to improve treatment,<br />

identify causal relationships and maintain<br />

the health of teeth and gums.”<br />

This study provides more representative<br />

data of the overall population than<br />

previous studies. It also demonstrates that<br />

meaningful insights can be gained through<br />

analysis of existing data from routine<br />

dental care. ■<br />
