Buccal plate regeneration with immediate postextraction implant placement and restoration: case reports.

The loss of the buccal alveolar plate following tooth extraction in the maxillary anterior region is an especially challenging condition for the clinician. Immediate implant placement with a flapless approach has been suggested in order to reduce postextraction bone loss. In the presence of a significant vertical gap in the buccal plate after tooth extraction, most authors still recommend a bone augmentation procedure before implant placement. In these reports, buccal bone plate regeneration was obtained through a flapless approach and immediate postextraction implant placement with a cancellous bone and collagen graft in the buccal gap.
