[Study on osteocompatibility of hydroxyl polycalcium sodium phosphate in vitro]

Hydroxyl polycalcium sodium phosphate(HP) is a new substitute material for human hard tissues. The isolated rat osteoblasts from the parietal and frontal bones of 1-3d SpragueDawley rats were used to estimate the osteocompatibility of HP in this study. The effects of the materials on cell morphology, growth and proliferation were determined. The result showed that rat osteoblasts could attach, spread and proliferate on HP as normal cells. The proliferation of cells on HP was more favour able to the adhesion and proliferation of rat osteoblasts and could form osteointegration early.
