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

Enrollment: 49
Study Start Date: August 2011
Estimated Study Completion Date: April 2016
Estimated Primary Completion Date: April 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: New abutment connection implant
Implant with new abutment connection
Device: New Abutment Connection implant
New abutment connection implant
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 lack of implant mobility and lack of bone loss obtained at various study time points
