摘要   作为缺失牙修复的一种先进技术,牙种植修复已在发达国家口腔医学领域开展多年.近年来,随着国外知名品牌种植系统的引进和国产种植系统的完善,国内开展的口腔种植也已经较为成熟.牙种植(dental implant)是指将无机的异体材料锚固(anchorage)在颌骨内,为缺失牙的修复体提供支持和固定[1].50年代中期,瑞典哥德堡大学的Branemark教授在研究骨微循环的试验中证实纯钛具有良好的生物相容性(biocompatibility),从而提出了种植体骨结合(osseointegration)理论,并将其定义为"负载的种植体表面与周围发育良好的骨组织之间在结构和功能上的直接结合"[2],该理论成为现代口腔种植学的理论基础.种植牙植入后能否在人体环境中长期正常行使功能,其稳定性是种植成功的关键,即种植体与骨组织之间获得了良好的骨性结合界面,称之为"骨整合".本文拟对目前增强种植体稳定性的骨整合促进技术作一简要综述.……
