Trefoil™ the next full-arch revolution A revolutionary fixed solution to treat more patients better. 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. By Mike Stuart The Trefoil system is a break- through in efficiency for treating the mandible. Previ- ously, pre-manufactured bars could be cost efficient, but passive fit posed a challenge. Now, Trefoil has overcome this with a unique fixa- tion mechanism, which can adjust to compensate for inherent devia- tions from the ideal implant posi- tion. This feat of engineering has enabled a new fixed solution that makes it possible for clinicians to offer patients fixed and definitive teeth in one day.* More patients benefit from a fixed solution Several studies confirm implant-as- sisted complete prostheses are more advantageous than conventional dentures.1 The benefits of fixed solu- tions can outweigh the cost of a fixed-removable for many patients when considering implant-support- ed solutions. As an elective surgery, clinicians must take into account many patient preferences and cir- cumstances. Developed with the needs of the many in mind, the effi- ciency of the Trefoil system empow- ers clinicians to provide many pa- tients who are held back by time or by finances with the premium-quali- ty, fixed solution they deserve. Even before la fits of the Tre experienced. A global, five-year multi-center study using the solution began in 2011 and has already yielded positive results.2 The hope is that, with the Trefoil system now widely available, patients around the world will soon experience changes in their life quality that this innovative new solution was designed to deliver. *Depending on clinician preference and close cooperation with the laboratory.

THE FIRST PRE-MANUFACTURED BAR WITH PASSIVE FIT The ingenious fixation mechanism is a breakthrough in treating the edentulous mandible. Anatomically designed for the natural arch of the lower jaw, the standardized bar contains adaptive joints that adjust to compensate for horizontal, vertical and angular deviations from the ideal implant position. P A T E N T P E N D I N G f o r f i x a t i o n m e c h a n i s m Angular deviation Horizontal deviation Vertical deviation ±4.0° ±0.4 mm ±0.5 mm PATENT PENDING FOR FIXATION MECHANISM Each mechanism has five self-adjusting joints that help correct the position of the pre-manufactured bar, enabling the passive fit of the definitive prosthesis. PROVEN STRENGTH WHEN PUSHED TO THE LIMIT The Trefoil system maintains its strength when pushed to the extreme of its compensation capability. In fact, tests3 prove almost no difference in fatigue limit between the maximum compensation configuration and the configuration without compensation.
