Trefoil™

The next full-arch revolution

The Trefoil system is a breakthrough in efficiency for treating the edentulous mandible with a fixed and definitive prosthesis on the day of surgery.1 Using a pre-manufactured titanium bar with a unique retention mechanism, it can adjust to compensate for inherent deviations from the ideal implant position and enable the passive fit of the definitive prosthesis. 

 

 

Main benefits

Definitive teeth in a day
The Trefoil system is an efficient solution that allows Immediate Function and makes fixed and definitive teeth on the day of implant surgery1 an option for more patients.

Straightforward prosthetic workflow
The pre-manufactured titanium bar simplifies the creation of the definitive acrylic prosthesis and saves substantial time for the restorative clinician and the lab.

The first pre-manufactured bar with passive fit
The pre-manufactured framework, anatomically designed for the natural arch of the mandible, contains adaptive joints that adjust to compensate for horizontal, vertical and angular deviations from the ideal implant position and enable the passive fit of the definitive prosthesis.

 

A breakthrough in workflow efficiency

An innovation that brings new efficiencies at almost every step – from manufacture of components to definitive restoration. The Trefoil system offers reduced chair time and shorter time-to-teeth compared to conventional treatment by combining:

  • A pre-manufactured titanium bar
  • A simplified restorative workflow
  • A fixed and definitive acrylic prosthesis
  • Reduced restorative componentry

Reduced chair time and restorative work
The restorative workflow is simplified thanks to the use of the pre-manufactured titanium bar.  An experienced clinician and lab will require approximately six hours of active working time. 

Shorter time-to-teeth
Unlike conventional treatments with provisional prosthetics, the Trefoil system enables a fixed and definitive prosthesis to be placed up to six months earlier.


Testimonials

Dr. Kenji Higuchi

“The Trefoil system embodies the Nobel Biocare objective – treat more patients better. With this improved efficiency comes the opportunity to bring the benefits of osseointegration to a whole new patient population.” Dr. Kenji Higuchi, US

Dr. Ruben Davo

“The Trefoil system makes it possible for me to deliver a definitive, mandibular fixed prosthesis to the patient on the day of surgery. It reduces treatment time and is more affordable for patients than conventional treatment methods that require a provisional prosthesis.“ Dr. Rubén Davo, Spain

Dr. Glenn Liddelow

“The Trefoil system provides an outstanding option for the edentulous patient and will provide an affordable, quality solution.” Dr. Glenn Liddelow, Australia
