The revolution in full-arch restoration. 

Definitive, fixed, full-arch solution in one day.*

Treating more patients better

The Trefoil system offers a high-quality, efficient, fixed solution for more edentulous patients and patients with failing dentition.1-3


A revolutionary fixed solution

The Trefoil system is a breakthrough in efficiency for treating the mandible.4,5 The pre-manufactured bar with a unique fixation mechanism can adjust to compensate for inherent deviations from the ideal implant position.1 That makes definitive teeth in a day a viable choice for more patients.*
Three ways the Trefoil system reduces chair time:

  • Pre-manufactured definitive bar with an acrylic prosthesis
  • A straightforward prosthetic workflow
  • Reduced restorative componentry due to compensation mechanism5

Simplified prosthetic workflow with pre-manufactured titanium bar anatomically designed for the natural arch of the mandible.

Adaptive joints adjust for horizontal, vertical, and angular deviation of the implant position.6

The Trefoil Bar simplifies the creation of the definitive acrylic prosthesis – saving substantial time for the restorative clinician and the lab.

The integral Trefoil Implant combines the proven parallel-walled design, a machined soft-tissue collar, and a conical connection.

Surgical workflow with template-guided surgery.

Definitive teeth in a day*

Quality solution with a 97.5% implant survival rate at 1 year4
