Brief summary

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

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.

Participant flow

Recruitment details

Up to 165 patients are expected to be enrolled across all centers, with enrollment efforts beginning in August 2008. Enrollment period remained opent until December 2010.

Pre-assignment details

Pre-treatment included a screening visit (enroll those meeting all protocol inclusion criteria), signing informed consent, and pre-surgical data collection. Patients returned for implant placement surgery, followed by restorative activities.
