Study Type: Interventional
Official Title: Ridge Preservation Comparing the Clinical and Histologic Healing of Flap vs. Flapless Approach to Grafting
Brief Summary: Ridge Preservation Comparing the Clinical and Histologic Healing of Flap vs. Flapless Approach to Grafting
Detailed Summary: Thirty patients will be treated using the principles of guided bone regeneration and ridge preservation. Fifteen test patients will receive the flapless technique with an intrasocket cancellous cortical particulate allograft plus a facial overlay graft using a bovine xenograft plus Alloderm GBR. The positive control group of fifteen patients will receive the flap technique with an intrasocket cancellous cortical particulate allograft plus a facial overlay graft using a bovine xenograft plus Alloderm GBR. Approximately, four months post-surgery, a trephine core will be taken from the grafted site immediately prior to implant placement and submitted for histologic processing.

Current Primary Outcome: Change in post-extraction site to 4 month change in crestal osseous width [ Time Frame: 4 months ]
Original Primary Outcome: Same as current
Current Secondary Outcome:
- Change in Soft tissue thickness [ Time Frame: 4 months ]Soft tissue thickness measurements taken with a #40 endodontic reamer.
- Percent osseous tissue [ Time Frame: 4 months ]A trephine core will be harvested at 4 months. Following histologic processing the osseous core will be classified into percent vital bone, nonvital bone and trabecular space.
Original Secondary Outcome: Same as current
