The Efficacy of Amniotic Versus Collagen Membrane in Immediate Dental Implant Augmented with Osteon™ II Collagen Bone Graft

Background: Dental implants are the most common solution for missing teeth, achieving osseointegration through a direct bond with living bone. Purpose:This study aimed to assess the effectiveness of amniotic membrane versus collagen membrane in immediate dental implant augmented with osteon™ II collagen bone graft in a follow up to 9 months by clinical and radiographic parameters. Methods:This research has been designed as a randomized controlled clinical study. Cases have been divided randomly into 2 equal groups by flip coin. Group Ι included cases that were treated with immediate implant augmented by Osteon™ ΙΙ collagen bone graft with collagen membrane. Group ΙΙ included patients that were treated with immediate implant augmented by Osteon™ ΙΙ collagen bone graft with amniotic membrane. Results: A statistically insignificant variance was discovered in clinical and radiographic parameters at different intervals. There was an improvement in marginal bone level, bone density, and marginal bone loss in both groups gradually, but no change in implant stability, mPI, MGI, and PP. Conclusion: The use of amniotic or collagen membrane combined with Osteon™ II collagen bone graft appeared to improve bone density and implant stability and maintain bone level around immediately placed dental implant during the observation period of the study. The use of amniotic membrane seemed to produce comparable clinical and radiographic results to collagen membrane in Guided Bone Regeneration (GBR) around immediate dental implant.
