Selective Bone Formation on Hydroxyapatite-Granule-Implanted Titanium


Article Preview

Hydroxyapatite (HA)-granule-implanted cylindrical titanium composites, which uniformly have HA granules on the curved surface, were formed by a hot pressing using HA-granuleimplantation system under the conditions of 1023 K, 1 h, 1960 N in vacuo. Cracks were not observed in the HA granules. The HA-granule-implanted titanium samples were implanted in a mandible of a dog. After 1 year, new thin bones like pillars were selectively structured on the HA granules with bone induction ability. The HA-granule-implantation technique is expected to be useful for designing shape of bone around titanium implant in order to match living bones.
