Various calcium phosphates are used for bone repair. Although hydroxyapatite (HA) sintered ceramics are widely used due to their osteo-conductivity, its bioresorbability is so low that HA remains in the body for a long time after implantation. In contrast, tricalcium phosphate (TCP) ceramics show resorbable characters during bone regeneration, and can be completely substituted for the bone tissue after stimulation of bone formation. Therefore, much attention is paid to TCP ceramics for scaffold materials for supporting bone regeneration. This paper reviews bioresorbable properties of calcium phosphate ceramics derived from beta-TCP and alpha-TCP.
