Study Summary
The purpose of this study is to compare marginal bone level changes between ASTRA TECH Implant System; Fixture ST and Biomet 3i; Osseotite® Implants. Subjects with partial edentulism in the posterior maxilla and/or mandible will be included and a one-stage surgical protocol will be used. Implants will be loaded within 15 weeks from installation. The subjects will be followed for 3 years.
Primary Outcome
Marginal bone adaptation was expressed as the distance from the implant reference point to the most coronal bone-to-implant contact on the mesial and distal side of the implant. Bone adaptation in millimeters at the 3-year follow-up visit were compared to values obtained at Implant placement (baseline). Positive value indicates bone gain and negative value bone loss.
Interventions
- DEVICE ASTRA TECH Implant System; Fixture ST: Ø 4.5 cm in lengths of 9, 11 and 13 mm.
- DEVICE 3i Osseotite® implant: Ø 4.0 in lengths of 8.5, 10, 11.5 and 13 mm
