This study will evaluate the contributions of the Nanotite implant design when used by graduate students in their first year of placing implants.

Condition Intervention
Tooth Disease Partial Edentulism Device: Nanotite dental implant Device: Osseotite dental implant

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment

Official Title: A Prospective Randomized-controlled Evaluation of Nanotite and Osseotite Surfaced Implant Performance in Graduate Student Programs

Further study details as provided by Zimmer Biomet:

Primary Outcome Measures:

Enrollment: 241
Study Start Date: April 2008
Study Completion Date: October 2012
Primary Completion Date: October 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Nanotite implant
Nanotite dental implant
Device: Nanotite dental implant
Nanotite root form titanium dental implant
Other Name: Nanotite endosseous dental implant
Active Comparator: Osseotite implant
Osseotite dental implant
Device: Osseotite dental implant
Osseotite Root form titanium dental implant
Other Name: Osseotite endosseous dental implant

Detailed Description:

This multicenter, prospective, randomized-controlled study will compare the performance of the Nanotite vs. the standard Ossotite implants when placed by graduate students with little or no prior experience. Enrolled patients will have the study site(s) randomized to either a Nanotite (test) or an Osseotite (control) implant. The manner of treatment observed at the participating center will be followed for this study.

Study Hypothesis: The performance of the Nanotite implant in this study will be no different than or superior to that of the Osseotite implant placed during the early period of graduate student training.
