설명

일반 설명

Bone and tooth implant materials have been prepared from polycrystalline hydroxyapatite. The compressive, flexural, torsional and dynamic torsional strengths of polycrystalline hydroxyapatite were investigated.[1] Electrophoretic deposition of hydroxyapatite on to flat titanium plate material has been studied.[1][2]

Hydroxyapatite is a bioceramic mainly found in minerals of bone and teeth.[3] Due to its high biocompatibility and similarity with inorganic components found in hard tissues, it is mainly used to produce biocomposites and prostheses for bones and teeth replacement.[4]

애플리케이션

Hydroxyapatite may be used in the preparation of bioceramic specimens by incorporation of a small amount of silicon (0.4wt%) into the structure of hydroxyapatite.[5] It may be used for the preparation of porous microstructures, having important prosthetic applications.[2]
