Zimmer Biomet Identifier:
First received: February 7, 2012
Last updated: March 30, 2017
Last verified: March 2017
Integration success rates measured by resistance to countertorque testing will be higher for the experimental implant design than for the control implants.

Condition Intervention
Partial Edentulism
Tooth Disease
Device: Implant with new abutment connection
Device: Nanotite Certain Tapered implant

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Investigator
Primary Purpose: Treatment
Official Title: A Prospective Randomized-controlled Study of the Integration Success Rate of an Implant System With a Novel Abutment Attachment in Cases Loaded Early

Further study details as provided by Zimmer Biomet:

Primary Outcome Measures:
  • Primary stability countertorque measures [ Time Frame: 2 months ]
    Resistance to countertorque measures showing primary stability success of implants

Secondary Outcome Measures:
  • Cumulative success rate [ Time Frame: 2 years ]
    Crestal bone regression (amount of bone loss measured) and equivalence in integration success (implant mobility)

Enrollment: 49
Study Start Date: July 2011
Study Completion Date: December 2016
Primary Completion Date: December 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: New abutment connection implant
Implant with new abutment connection
Device: Implant with new abutment connection
New abutment connection implant system
Other Name: Osseotite Endosseous dental implant
Active Comparator: Nanotite Certain Tapered implant
Nanotite Certain Tapered (standard abutment connection) implant
Device: Nanotite Certain Tapered implant
Nanotite Certain Tapered (standard abutment connection) implant
Other Name: Nanotite endosseous dental implant

Detailed Description:
In this study patients are randomized to receive either the experimental implant system or the control Nanotite Certain Tapered (standard abutment connection) and assessed for integration success measured by countertorque testing and cumulative success rate in cases that are loaded early
