Abstract

INTRODUCTION: The Amnion Chorion Membrane (ACM) has favorable regenerative properties which facilitates its use for covering immediate dental implants. OBJECTIVES: To evaluate clinically and histologically the effect of Amnion Chorion membrane in augmenting immediately placed dental implants compared to connective tissue graft (CTG) MATERIALS AND METHODS: This study was conducted clinically on eighteen upper hopeless anterior/premolar teeth scheduled for extraction and immediate implant placement. Patients were divided into two groups: in the first group, nine immediate implants were covered with ACM, and in the second group nine immediate implants were covered with CTG. Keratinized mucosal width (KMW), keratinized mucosal thickness (KMT) and healing score were recorded for both groups at 7 , 14 , 30 and 90 days RESULTS: The KMT showed an increase by 26% in the test group while in the control group it decreased by 6.5% by the end of the study period. Regarding the healing scores both groups showed marked improvement throughout the study, lower values of healing scores were noted in the test group. Clinical results were confirmed by histological examination which revealed that oral mucosa of both groups showed parakeratinized gingival epithelium. The connective tissue of the test group showed more regularly arranged ,thick bundles. CONCLUSIONS Both treatment modalities were satisfactory but the ACM offered more positive results concerning the mucosal thickness and healing scores.
