The aim of this study is to evaluate treatment effects of novel GBR membranes (PDLLAmembranes) applied to bony defects around dental implants on new bone regeneration alone or incombination with bioceramic bone graft (BIO-OSS®) on the mongrel dog model in comparisonwith collagen membrane (BIO-GIDE®) and therefore to assess the clinical values of the novel GBRmembranes and bioceramic bone graft material in dental implantology. 6 implants were placed inbilateral mandibular of each mongrel dog after preparation of mid- crestal defects. The defects onone side were covered with PDLLA membranes alone or with bone graft, while the contra-lateralsides received collagen membranes alone or with bone graft. These animals were sacrificed at 2, 4,8,12 weeks post the GBR-operation. And gross sample examination, standardized radiographs,99mTc-MDP SPECT and histomorphometric analysis were taken. All examinations showed similaramounts of newly formed bone beneath both types of barriers. The PDLLA or collagen membranewith bone graft groups showed better results than the membrane used alone groups. The resultsindicated that PDLLA membranes especially with bioceramic bone graft presented an improvedresponse in dealing with bony defects around implants
