寻找和研制最佳的移植材料一直是口腔颌面外科和成形外科共同关心的问题。近年来有关异体骨的应用有了很大进展,移植后具有一般自体骨诱导成骨的活性。但异体骨的抗原性经冷冻等方法处理后仍不能完全消除。脱矿骨、胎儿骨和异种胶原不具有抗原性的优点引起了人们的重视。本文仅就这些材料的性质和应用综述如下。一、脱矿骨的成骨性能 Finding and developing the best implant materials has always been a common concern in oral and maxillofacial surgery and plastic surgery. In recent years, the application of allogeneic bone has made great progress, with the general autologous osteoinductive osteogenesis after transplantation. However, the antigenicity of allogeneic bone can not be completely eliminated by the methods such as freezing. Demineralized bone, fetal bone and xenogeneic collagen has no antigenicity has attracted people's attention. This article reviews the nature and application of these materials only. First, demineralization bone osteogenic properties
