Evaluation of amnion chorion membrane for socket preservation after the extraction of maxillary single rooted teeth: A randomized controlled clinical trial

Abstract

Introduction: The aim of this study was to assess the efficiency of using dehydrated de-epithelial ized amnion chorion membrane (ddACM) on socket preservation in the anterior region, clinically and radiographically.

Methods: 26 unrestorable maxillary anterior or single rooted premolars, with buccal fenestration, were selected. The socket was filled with allograft material and covered with ddACM for the test group, and allograft material with a collagen membrane for the control group divided equally. Clinical parameters including gingival healing and tissue thickness was assessed. Volumetric bone change was measured 4 months later using a CBCT.

Results: Test group showed clinical statistically significant results than the control group (P-value = 0.020, effect size = 0.574) along with a radiographic higher mean bone width measurement than control group after four months (P-value = 0.372, Effect size = 0.357).

Conclusion: As compared to collagen membrane, intentionally exposed ACM is similarly successful in ridge preservation. Moreover, the use of ACM may help to reduce postoperative VAS ratings and may result in excellent bone quality available for implant placement.
