Present situation and prospect of hydroxyapatite bioceramic materials

Hydroxyapatite bioceramic has been widely used as reconstructive and prosthetic material for osseous tissue such as bone and tooth, owing to its excellent biocompatibility and tissue bioactivity. There are many methods to synthesize the dense and porous hydroxyapatite material. But the poor mechanical property of hydroxyapatite restricts the further application of the material . In order to enhance the comprehensive performance of the material,many researches have been dedicated to the synthesization of the composite bioceramic materials.
