Clinical Assessment of Dental Implant

Not Applicable

Completed

• Conditions: Tooth Loss
• Interventions: Device: MIS Implants

• Registration Number: NCT02591706
• Lead Sponsor: University of Liege

Brief Summary

Primary Endpoints : The implant survival and success rate of V3 and C1 implants will be compared. Implant success rate will be evaluated by measuring the peri-implant bone remodeling from baseline to 1 year post insertion.

The hypothesis is those implant survival rates of the test (V3) and control group (C1) are similar and that test V3 implant allows less peri-implant bone loss.

Secondary Endpoints : The thickness of hard tissue in the buccal aspect of the V3 and C1 implants will be compared. The bone thickness will be measured in cone beam computerized tomography (CBCT) on the day of implantation, 4 and at one year after the final restoration.

The hypothesis is that V3 implant allows thicker bone dimension in the cervical area.

Arm && Interventions

Group	Intervention	Description
Dental implant (V3)	MIS Implants	The unique triangular shape of the coronal portion of the V3 implant results in less titanium and more bone and soft tissue visible in the esthetic zone, for a restorative-driven approach and easier soft tissue management. The V3 provides doctors with a more advantageous starting point; where greater volume of bone and soft tissue is achieved at the onset of implant placement. Patient will be randomly assigned to one of the two groups after flap opening.
Dental implant (C1)	MIS Implants	Internal Conical Connection: The C1 has a six-position cone index, except for the C1 narrow platform that has a four-position cone index. The conical connection is 2.00mm in depth, with a 12° cone. As a result of our meticulous manufacturing process a perfect fit between the implant and the abutment is achieved, eliminating micro-movements and minimizing bone resorption. Patient will be randomly assigned to one of the two groups after flap opening.
