This in vivo study was to examine the historical changes of implanted novel chitosan/collagen composite barrier for confirming the clinical feasibility. Four other commercial GTR membranes were chosen for comparison. Among the resorbable GTR membranes, BioMend Extend and Peri-Aid are collagen base, and GORE-TEX OSSEOQUEST is synthesized membrane, while GORE-TEX e-PTFE (Expanded polytetrafluoroethylene) is synthesized but non-resorbable. Beagle dogs were used as animal model. Buccal mucoperiosteal flaps were reflected in the bilateral mandibular premolar and molar areas. Buccal alveolar bone was reduced on 1st、2nd premolar and molar to a level 5 mm apical to the cemento-enemel junction. Root surface was denuded of periodontal ligament and cementum, and notches were placed at the bone level of each root. The tested GTR barriers were implanted in critical bone defect areas. Flaps were coronally positioned and sutured. Two beagle dogs were sacrificed each time as the designed time period after surgery. Histological and histometirc evaluation at 7 days、14 days、28 days、3 months were performed post-operatively to determine the healing response of each treatment modality.
