Ridge Preservation Comparing the Healing With or Without a Barrier Membrane

Overview

Ridge Preservation Comparing the Clinical and Histologic Healing of Membrane vs. no Membrane Approach to Grafting.

Thirty patients will be treated using the principles of bone grafting for ridge preservation. Fifteen test patients will receive a flap technique with an intrasocket cancellous cortical particulate allograft plus a facial overlay graft using a bovine xenograft without a membrane where only the exposed intrasocket allograft will be covered with a piece of Alloderm GBR. The positive control group of fifteen patients will receive a flap technique with an intrasocket cancellous cortical particulate allograft plus a facial overlay graft using a bovine xenograft plus Alloderm GBR membrane. 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.

Outcomes

Primary Outcomes

Change in post-extraction site to 4 month change in crestal osseous width

Changes in post-extraction to 4 month change in ridge measurements at the mid defect alveolar crest and 5 mm apical taken with a caliper.

Time frame: 4 months

Secondary Outcomes

Change in Soft tissue thickness

Soft tissue thickness measurements taken with a #40 endodontic reamer.

Time frame: 4 months

Percent osseous tissue

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.

Time frame: 4 months
