Guided Bone Regeneration (GBR) Using a Collagen Membrane Barrier Technique Along With Full Thickness Buccal Mucoperiosteal Flap For the Preservation of the Alveolar Ridge Following Tooth Extraction.

Abstract

Introduction: The preservation of the alveolar ridge following tooth extraction is important for maintaining optimal dental health and ensuring successful future dental interventions. Various techniques for alveolar ridge preservation are done, including socket grafting and the use of biomaterials, membranes, and growth factors, which have a plenty of clinical benefits, such as improved aesthetics and stability for dental implants along with potential cost-effectiveness compared to more invasive procedures, thus optimizing treatment outcomes and promoting long-term dental health.

Aim: To assess the effectiveness of bone graft material and collagen membrane for ridge preservation following tooth extraction compared to tooth extraction alone group.

Materials and method: Ninety patients presenting with the need for extraction were included in this study.They were divided into three groups. In group A, the socket was filled with bone allograft and protected with a fish derived collagen membrane without buccal thickness flap. In group B, buccal/labial thickness flap was elevated, socket was filled with bone allograft and protected with a fish derived collagen membrane barrier, and in group C, no bone graft and collagen membranes were placed.

Results: Showed that group A is much more beneficial and simpler than the group B procedures.

Conclusion: Bone regeneration using collagen membranes and inorganic bovine bone combination seems promising. But, there is obviously a need for long-term studies to confirm the success rate of ridge preservation procedures using buccal full thickness flap and without buccal full thickness flap.
