摘要：

The development of calcium phosphate ceramics and other related biomaterials for bone graft involved a better control of the process of biomaterials resorption and bone substitution. The bioactive concept was developed for biphasic calcium phosphate ceramics (BCP). An optimum balance of the more stable phase of HA and more soluble TCP was obtained for controlling gradual dissolution in the body, seeding new bone formation as it releases calcium and phosphate ions into the biological medium. The bone/material interface and the events occurring in the development of this dynamic interface such as cellular response, biodegradation or bioresorption of the materials and their transformation to carbonate hydroxyapatite (CHA) were described. These processes were observed in both bulk samples, implant coating and injectable bone substitute (IBS). (C) 1998 Elsevier Science Ltd. All rights reserved.
