Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Partial Edentulism Tooth Disease Device: T3 with DCD tapered Prevail implant Device: Nanotite Certain tapered implant Not Applicable

Detailed 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.

Device: T3 with DCD tapered Prevail implant
T3 with DCD implant with Certain (internal) connection and platform-switch design
Other Names:
  • T3 with Nanotite
  • T3 with platform switch

Active Comparator: Nanotite certain tapered implant

Primary Outcome Measures :
  1. Cumulative success rate [ Time Frame: 1 year ]
    Implant mobility is assessed by clinical evaluations and correlation to initial placement stability- insertion torque profiles.

Secondary Outcome Measures :
  1. Crestal bone changes [ Time Frame: 2 years ]
    Crestal bone regression (amount of bone loss) between the two treatment groups will be compared
