| Research Abstract |
We are investigating to regenerate bone by osteogenesis using gradually expanding the interface between bone surface and periosteum. In this study we developed the new dental implant system to obtain quick and broad adherence to surrounding bone to use for the regenerated bone. We evaluated thin amorphous calcium phosphate films coated on the surface of titanium dental implants using magnetron sputtering. The coated thin amorphous phosphate films induced early not only distance osteogenesis from the bone surrounding implants but also inner osteogenesis in the surface layers of the films. The implants showed early good mechanical fixation.These results suggested that implants coated with thin amorphous phosphate layers improve implant fixation and accelerate bone response.
