Study of a method to prepare novel carbonate-containing apatite porous bodies
Bone apatite contains about 5 to 8% carbonate groups. Sintered carbonate-containing apatite has been proposed as a bone substitute material due to its excellent biocompatibility and bioabsorbability. However, sintering increases crystallization, carbonate ions are lost, and absorbability decreases....

Summary: | Bone apatite contains about 5 to 8% carbonate groups. Sintered carbonate-containing apatite has been proposed as a bone substitute material due to its excellent biocompatibility and bioabsorbability. However, sintering increases crystallization, carbonate ions are lost, and absorbability decreases. Therefore, we examined the transition conditions of carbonate-containing apatite in solution at a temperature close to that of the living body to develop a method to obtain unsintered carbonate-containing apatite. Using dibasic calcium phosphate dihydrate as the starting material, carbonate-containing apatite with continuous pores and more carbonic acid groups than the sintered material could be produced. |
