摘要
背景:钛合金质量较轻、密度低,具有抗电化学腐蚀、良好的生物相容性、低弹性模量和高强度等优异性能,已被广泛应用于口腔医学。目的:总结近年来口腔生物材料钛合金种植体的临床应用进展。方法:由作者应用计算机检索1998-01/2010-10维普数据库中与口腔生物材料钛合金种植体有关的文献,检索关键词为"钛合金,种植,生物相容性"。结果与结论:目前的研究大多数集中于钛合金种植体的生物相容性研究。国内外学者们正在努力寻求更加理想的钛合金种植体表面结构来提高种植体的骨结合能力,此对种植体骨性结合界面形成也极其重要。钛合金种植体的表面处理对提高种植成功率起着重要作用,不同处理方法都有其优点,但共同的特点是形成粗糙表面,使其具有更好的生物活性与骨结合能力。因此寻找一种能兼具各方面优点,更好促进骨结合的表面处理方法,已成为近年来口腔种植学研究的热点。
BACKGROUND： Titanium alloy quality was light and density was low. Titanium alloy has the characteristics of anti-electrochemical corrosion, good biocompatibility, low elastic modulus and high intensity, and has been extensively used in stomatology. OBJECTIVE： To summarize the clinical application progress of oral biomaterial titanium alloy implant. METHODS： We retrieved Vip Database for articles concerning oral biomaterial titanium alloy implant published from January 1998 to October 2010. The Keywords were ＂titanium alloy, implant, biocompatibility＂. RESULTS AND CONCLUSION： At present, numerous studies have addressed biocompatibility of titanium alloy implant. Scholars tried to seek ideal surface structure of titanium alloy implant to elevate the osseointegration ability of implant. This plays an important role in formation of osseointegrated interface of implant. Surface treatment of titanium alloy implant exerts a crucial effect on implant successful rate. Different treatment methods have their advantages, but their common characteristic is to form crude surface and to improve biological activity and osseointegration ability. Therefore, to seek a surface treatment method that has various advantages and contributes to osseointegration has been a hot point in the recent study of oral implant.
