Abstract:The purpose of this study is to evaluate the availability of a bioabsorbable collagen barrier-membrane for guided bone regeneration (GBR). Subjects were 18 beagle dogs and materials were dome-shaped membranes. Prior to experiments, both first molars in the mandible were extracted. After 3 months of healing, mucoperiosteal flaps were reflected and experimental defects created in the alveolar bone. Theexperimental bone defect on one side was completely covered with the membrane (experimental group). On the contr… Show more
