Purpose
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.
| Condition | Intervention |
|---|---|
| Jaw, Edentulous, Partially | 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 |
| Study Type: | Interventional |
| Study Design: | Allocation: Randomized Intervention Model: Parallel Assignment Masking: None (Open Label) Primary Purpose: Treatment |
| Official Title: | An Open, Randomized Study to Compare Two Dental Implant Systems With Regard to Changes in Marginal Bone Level. |
Further study details as provided by Dentsply Sirona Implants:
Primary Outcome Measures:
- Marginal Bone Level Changes [ Time Frame: 3 years after implant placement (baseline) ]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.
