Immediate implant placement following a modified trephine/osteotome approach: success rates of 116 implants to 4 years in function.
OBJECTIVE
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.


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.


CONCLUSIONS
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%.


CONCLUSIONS
No implants have been lost or are failing in function.
