| Research Abstract |
A fabrication process of Ca-deficient HA with controlled composition and morphology of the particles which construct the HA ceramics was established by selecting the starting material and hydrothermal conditions. The possibility that the Ca-deficient composition and morphology of the particles affect the behavior of the HA ceramics in vivo was revealed. Moreover, it was revealed that the rod-shaped particles prevent the brittle fracture. From these results, we obtained the basic knowledge about the creation of bioresorbable bone substitute materials.
