This study was performed to improve the efficiency of guided bone regeneration by adapting the tissue-engineered bone regeneration approach. The PHBV-collagen nonofibrous membranes cultured with rat calvarial periosteum derived cells in osteogenic culture medium for 7 days were applied to 5 x 2mm size artificial rat tibial defects for 3weeks and evaluated its efficiency as an alternative cell engineered membrane for effective guided bone regeneration by routine histological observation. The defects covered with cell attached PHBV collagen nanofibrous membrane complexes showed favorable bone repair compared to both membrane non-covered control and membrane only covered group without specific side effects. These findings suggest that the favorable guided bone generation can be achieved by adapting the tissue engineered bone regeneration approach using PHBV-Collagen nanofibrous membrane scaffold.
