ABSTRACT

Objectives: This Study Was Aimed To Evaluate The Efficacy Of Amniotic Membrane Versus Collagen Membrane In Guided Bone Regeneration Around Immediately Placed Dental Implants Into Fresh Extraction Sockets. Methods: Fourteen Patients, 4 Males And 8 Female With A Mean Age Of 28.86�4.33 Years Underwent Extraction Of One Maxillary Premolar And Immediate Replacement With Dental Implant. The Patients Were Equally Divided Into Two Groups. In The First Group, Amniotic Membrane Was Used While In The Second Group, Collagen Membrane Was Used To Cover Immediate Implant And Biphasic Calcium Phosphate Bone Graft. All Patients Were Evaluated Clinically And Radiographically At 3, 6 And 9 Months Postoperatively. All Clinical And Radiographic Parameters Were Subjected To Statistical Analysis.

Results: During 9 Months Interval, In Both Groups, No Implant Was Lost And All Implants Showed Favorable Clinical And Radiographic Findings. There Were No Significant Differences In Modified Plaque Index And Modified Sulcus Bleeding Index At All Follow Up Visits. Periotest Values For Both Groups Decreased Through All Follow Up Periods With No Statistically Significant Difference. Radiographic Analysis Revealed That There Was No Statistically Significant Difference Between The Two Groups In Marginal Bone Loss.

Conclusions: Amniotic Membrane Is As Effective As Collagen Membrane In Guided Bone Regeneration Around Immediately Placed Dental Implant.
