Overview
Brief Summary
alveolar ridge preservation using deep collagen layer, xenograft and collagen membrane seal versus the use of xenograft and collagen membrane seal alone. Measuring the clinical and radiographic alveolar ridge dimensional changes following after preservation at the time of implant placement
Detailed Description
alveolar ridge preservation using deep collagen layer, xenograft and collagen membrane seal versus the use of xenograft and collagen membrane seal alone. The primary objective of the study is measuring the clinical and radiographic alveolar ridge dimensional changes following the procedure 4 months post operatively The secondary objective : * Histological assessment of alveolar bone specimens to assess bone remodeling and new bone formation in both studied groups after four months. * Patient satisfaction after implant placement
