摘要：

Carbonate apatite (CO(3)Ap), an inorganic component of human bone, has been clinically applied as an artificial bone substitute. In this study, the effects of the CO3 content in CO(3)Ap on the replacement by new bone were studied by fabricating CO(3)Ap granules containing 0.9-8.3 wt% of CO3. The dissolution rate of CO(3)Ap in a weak acidic solution, mimicking the Howship's lacunae, was rapid for the CO(3)Ap granules containing a larger amount of CO3. Histological analyses demonstrated the rapid resorption in CO(3)Ap and replacement by natural bone tissue when the CO3 content was increased. Therefore, the CO3 content in CO(3)Ap is a key factor that influences the replacement of the bone tissue.
