This trial is active, not recruiting.

Conditions partial edentulism, tooth disease
Treatments t3 with dcd tapered prevail implant, nanotite certain tapered implant
Sponsor Zimmer Biomet
Start date April 2013
End date July 2017
Trial size 100 participants
Trial identifier NCT02161874, 3023


This study evaluates the T3 implant system for the preservation of alveolar crestal bone and the establishment of initial integration. The new surface-treated features of the implant may contribute to improved soft and hard tissue healing. The success rate of the T3 implant will be no different than that of the control implant, which possess similar geometry but different surface treatments.

Additional Information

Official title A Prospective, Randomized-controlled Evaluation of Biomet 3i's T3 Implant System for Integration Success and the Preservation of Crestal Bone
Principal investigator Nicholas Lewis, DMD
Description This prospective, randomized-controlled study will enroll qualified patients with partial edentulism who will be treated with at least two dental implants. Implant sites will be randomly assigned to receive either a test (T3 implant) or control (Nanotite Certain Tapered implant) with an 80:20 (test:control) randomization ratio. All implants will be allowed to integrate without occlusal forces and final restorations will be cemented thereafter. Cumulative success rate and crestal bone regression of both treatment groups will be the primary and secondary study endpoints, respectively.
