Research Abstract

We hypothesized that octacalcium phosphate (OCP) can be used as an effective bone substitute. The present study was designed to investigate if bone repair is enhanced when OCP is implanted and which cell population is involved in bone formation caused by the OCP implantation. The OCP was prepared according to the method by LeGeros. Ground granules of between 32 and 48 mesh (particle sizes: 300 to 500 μm) were used for the implantation. The OCP was implanted into the bone marrow, the subperiosteal region and the standardized trephine defect of parietal bones in rats.
The following were suggested from the results of our experiments. First, the implanted OCP could be resorbed by multinucleated giant cells which share some ultrastructural characteristics with osteoclasts. Second, the implanted OCP may act on osteoblasts, bone lining cells and/or their closely committed progenitors on the bone surface to express the phenotype and deposit new bone around the OCP. Third, the implanted OCP may serve as a core for initial bone formation in the defect and promote bone repair. The present studies demonstrated that OCP can be used as an effective bone substitute.
