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
