摘要
羟基磷灰石生物陶瓷与人体的无机组成和晶体结构相似 ,具有良好的生物活性和生物相容性 .多孔羟基磷灰石生物陶瓷 ,其相互连通的微孔有利于组织液的微循环并为羟基磷灰石深部的新生骨提供营养 ,促进纤维组织和新生骨的结合和生长 ,是一种性能优异的硬骨组织替代材料 .近年来 ,发明了一系列制备多孔羟基磷灰石陶瓷的方法 ,如有机泡沫浸渍法、添加造孔剂法、快速成型法等 .对于多孔羟基磷灰石生物陶瓷的研究 ,注重研究孔尺寸对多孔体与组织之间相互关系的影响 ,并逐步实现了对多孔体孔径的控制 .本文综述了多孔羟基磷灰石生物陶瓷的制备工艺、生物特性和发展趋势 .
Hydroxyapatite, with similar inorganic composition and crystal structure to natural bone and tooth, has good bioactivity and biocompatibility. Because porous hydroxyapatite, with internconnected pores, allows tissue fluid circulation and provides nutrient for new bone , it leads to the combination fiber tissue with new bone. Therefore, it 's a good type of biomedical material used to replace the hard tissue of human bone. In term of the research of porous hydroxyapatite, the effects of pore size on porous implants and tissue are paid attention to. In order to investigate the structure of porous implants, a series of preparation methods such as infiltrating organic foam and adding pore-forming agent and rapid prototyping are invented to control the pore size of porous implants .The recent developments in preparation and biologic characteristics of porous hydroxyapatite are reviewed in this paper.
