ABSTRACT
The Amount Of Hard Tissue Resorption Following Tooth Extraction Sometimes Jeopardizes Prosthetically Driven Implant Placement; Therefore, There Is Great Interest In Socket Preservation Techniques That May Result In Less Alveolar Bone Loss. For The Most Part, Research Has Focused On The Healing Of Alveolar Sockets And The Ramifications Of Post Extraction Implant Placement. The Alveolar Bone Crest Is Known To Lose Volume During The First 6 Months After Tooth Extraction, Mostly On The Buccal Wall. The Aim Of The Presented Study Is To Evaluate Clinically And Radiographically A New Alternative Technique For Socket Preservation By Placement Of Collagenated Cortico-cancellous Xenograft Over An Intact Buccal Plate After Extraction. Ten Patients Were Selected Who Need Extraction For Non-restorable Single Rooted Teeth Where Atraumatic Extraction Was Performed Using Periotome And Forceps And A Surgical Caliper Was Used To Measure The Buccolingual Dimension At A Midpoint Then A Periosteal Elevator Was Used To Carefully To Create A Pouch On The Buccal Aspect At Midpoint Areas Of The Socket. Prehydrated Collagenated Cortico-cancellous Xenograft, Composed Of 80% Granulated Mix & 20% Collagen Gel?,which Is In A Paste Form Presented In Syringe Was Next Placed In The Pouch Overlying The Buccal Plate With Its Syringe. Clinical And Radiographic Examination Was Done For Each Patient By A Cone Beam C.T (CBCT) At The Pre-determined Follow Up Periods: Immediate Postoperative (base Line) And Four Months Postoperatively. Either Using Cone Beam Or Caliber; There Was No Statistically Significant Change In Mean Bone Width Measurements After 4 Months.
