Immediate Implant Placement Following a Modified Trephine/Osteotome Approach: Success Rates of 116 Implants to 4 Years in Function
Fugazzotto, Paul A.
Purpose: A technique is presented which utilizes a trephine with a 3.0-mm external diameter followed by an osteotome to implode a core of maxillary posterior alveolar bone prior to immediate implant placement.
Materials and Methods: The technique and its indications and contraindications are described in detail.
Results: One hundred sixteen implants were placed and uncovered utilizing this technique. Two implants were mobile at the time of uncovering.
Discussion: One hundred fourteen implants were restored and have been functioning successfully for up to 4 years according to the Albrektsson criteria, yielding a success rate of 98.3%.
Conclusion: No implants have been lost or are failing in function.
