Clinical Trial Summary

This prospective, randomized study will evaluate the performance of the Osseotite Certain Prevail implant when compared to that of the non-lateralized version of the implant.

Study (null) hypothesis: the crestal bone changes that take place after placement and loading of the Osseotite lateralized implants will be the same as for a similar but non-lateralized Osseotite Certain implant.

Description:

This is a prospective, randomized, longitudinal study in which qualified patients with partial edentulism will receive a short-fixed bridge restoration. Each implant site is randomized to receive either the Osseotite Certain Lateralized (test) or the Osseotite Certain Non-lateralized (control). All implants will receive a temporary prosthesis after two months of placement. Enrollment will include up to 20 patients (approximately 60 implants per center) at each participating study center.
