Randomized Study of Osseotite Certain Tapered Prevails vs. Osseotite Certain Tapered (Bolivar)

This study has been completed.
Information provided by (Responsible Party):
Zimmer Biomet Identifier:
First received: February 7, 2012
Last updated: March 28, 2017
Last verified: March 2017
This study will demonstrate the benefits of platform switching design of the Osseotite dental implant.

Condition Intervention
Partial Edentulism Tooth Disease Device: Osseotite Certain Tapered Prevail Device: Osseotite Certain Tapered

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Prospective Randomized-controlled Evaluation of the Osseotite Certain Tapered Prevail Implant for the Preservation of Crestal Bone

Further study details as provided by Zimmer Biomet:

Primary Outcome Measures:
  • Cumulative Success Rate [ Time Frame: 3 years ]
    An implant will be considered successful if it is immobile when tested at various study time point

Secondary Outcome Measures:
  • Crestal Bone Regression [ Time Frame: 3 years ]
    Differences in crestal bone levels obtained at various study time points will be compared between the two implant designs

Enrollment: 92
Study Start Date: November 2010
Study Completion Date: December 2016
Primary Completion Date: December 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Osseotite Certain Tapered Prevail
Osseotite Certain Tapered Prevail design with platform switching feature
Device: Osseotite Certain Tapered Prevail
Osseotite implant with platform switching feature
Other Name: Osseotite endosseous dental implant
Active Comparator: Osseotite Certain Tapered
Osseotite Certain Tapered implant with non-platform switching design
Device: Osseotite Certain Tapered
Osseotite implant with non-platform switching feature
Other Name: Osseotite endosseous dental implant

Detailed Description:
The Osseotite Certain Prevail implant with its platform switch feature will demonstrate higher success rate than the non-platform Osseotite Certain implant
