Trefoil™ – The next full-arch revolution

by: Mike Stuart

Nobel Biocare has led innovation in full-arch solutions for over 50 years. The latest addition to the company’s already extensive assortment of innovations for full-arch rehabilitation is the perfect example of this approach in action.

The Trefoil system

The Trefoil system is a breakthrough in efficiency for treating the mandible. Previously, manufactured bars might have been cost-efficient, but passive fit always posed a challenge. Now, Trefoil has overcome this drawback with a unique fixation mechanism, which can adjust to compensate for inherent deviations from the ideal implant position. This feat of engineering lies at the heart of a new fixed solution that makes it possible for clinicians to offer patients fixed and definitive teeth in a single day.*

The Trefoil system's pre-manufactured bar with passive fit

Patent pending for fixation mechanism: Each mechanism has five self-adjusting joints that help correct the position of the prefabricated bar, enabling the passive fit of the definitive prosthesis.

Trefoil system's compensation

Proven strength when pushed to the limit: The Trefoil system maintains its strength when pushed to the extreme of its compensation capability. In fact, tests prove almost no difference in fatigue limit between the maximum compensation configuration and the configuration without compensation.

More patients can now benefit from a fixed solution

For a very large number of patients, conventional dentures do not provide an adequate solution to their masticatory, esthetic or even social needs. Consequently, the benefits of fixed solutions often outweigh the perceived lower cost of dentures— or even a fixed-removable—for many patients. For patients considering implant-supported solutions, the Trefoil system offers a fast, affordable, state-of-the-art fixed treatment solution.

Shorter treatment times with the Trefoil system

Definitive teeth in one day:* The Trefoil system is a cost-efficient solution that allows Immediate Function and makes fixed and definitive teeth on the day of implant surgery* an option for more patients.

Possible time savings with the Trefoil system

Straightforward prosthetic workflow: The restorative workflow is simplified thanks to the use of the pre-manufactured bar. An experienced clinician and lab will require approximately six hours of active working time to create the definitive acrylic prosthesis.***

Developed with the needs of the many in mind, the efficiency of the Trefoil system empowers clinicians to provide many patients who are held back by time or by finances with the premium-quality, fixed solution they deserve.**

Even before launch, the patient benefits of the Trefoil system are clear. A global, five-year multi-center study using the solution began in 2015 and has already yielded very telling results. With the Trefoil system now widely available, many more patients around the world will soon be able to experience the quality of life improvements that Trefoil was designed to deliver.
