This is a prospective, randomized-controlled study where patients with qualifying partial edentulism received a short fixed bridge restoration. Each implant site was randomized to receive either the test (Osseotite Certain Prevail) or the control non lateralized version of the Osseotite Certain implant. All implants were placed in a single-stage manner with temporary provisionalization taking place two months after implant placement. Enrollment continued until 10 patients (approximately 30 implants) were treated at each participating study center.
