Bone regeneration in extraction sites. Part 2: The staged approach.
The use of guided tissue regeneration in conjunction with implants is a routine procedure in oral implant reconstruction. Three patient reports of the staged approach are presented and discussed. Implants were placed in regenerated bone 9 months after augmentation. Barrier membranes, with and without supporting screws, were used in different types of extraction site defects and followed for 2 years postoperatively.
