The purpose of this study was to evaluate histologic result of bone substituting materials on extraction sockets. We compare the histologic findings of control, MBCPⓡ, Polyboneⓡ. Mandibular premolar teeth of Beagle dogs were extracted available for bone filling. All alveolar extraction sockets were thoroughly debrided with surgical curet to remove the periodontal ligament. The graft materials were filled into the extraction sockets. The animals were sacrified 90 days after implantation. Both treated and control mandibular sites were histologically evaluated with light microscopy. Histological observation at 90 days revealed that control and experimental sites were healed uneventfully without any adverse tissue reaction. Regenerated new bone formation ratio is 34.5% for control, 28.4% for MBCPⓡ, 23.8% for Polyboneⓡ. From this results, it was suggested that MBCPⓡ, Polyboneⓡ are promising bone substituting materials to promote normal tissue healing and new bone formation.
