摘　　要：背景:近来,氧化锆陶瓷种植体开始被报道应用于临床。为了促进种植体的骨结合,提高成功率,学者们对其表面处理作了很多研究,但目前尚无公认的氧化锆种植体表面处理技术。目的:总结介绍氧化锆种植体表面处理技术的研究进展。方法:由第一作者用计算机检索中国期刊全文数据库(CNKI:2000年1月至2016年10月),Pub Med和Web of Science数据库(2000年1月至2016年10月),检索词为:氧化锆、氧化锆种植体、表面处理"和e treatment"zirconia or zirconium,implant,surfac",语言分别设定为中文和英文。对氧化锆种植体表面处理的技术进行总结,对氧化锆种植体的性质、表面处理技术和商品化情况等方面进行介绍。结果与结论:共纳入23篇文章。结果表明,目前常见的氧化锆种植体的表面处理技术有喷砂、酸蚀、喷砂酸蚀、选择性渗透酸蚀、激光、紫外线和表面涂层处理,均都能一定程度地提高种植体表面活性,增大粗糙度,促进骨结合。但由于氧化锆种植体的研究很有限,仍需要大量的实验来探究最适宜的表面处理技术。BACKGROUND： Recently, zirconia ceramic implants have been reported to be used in clinic. Increasing studies on surface treatment of ziconia implants have been done, in order to promote bone-implant osseointegration and increase the success rate of implantation. There are no recognized surface treatment techniques of zirconia implants as yet.OBJECTIVE： To summarize the research progress in surface treatment techniques of zirconia implants.METHODS： The first author searched the CNKI, PubMed and Web of Science databases for relevant articles published from January 2000 to October 2016. The keywords were ＂zirconia or zirconium, implant, surface treatment＂ in Chinese and English, respectively. The search condition was＂（（zirconia or zirconium） AND implant） AND surface treatment＂. Here,we reviewed the surface treatment techniques of zirconia implants, and introduced the properties, the surface treatment techniques and commercialization of zirconia implants.RESULTS AND CONCLUSION： Totally 23 papers were included in result analysis. Commonly used surface treatment technologies of zirconia implants include sand blasting, acid etching, sandblast and acid-etching, selective filtration etching, laser, ultraviolet and coating. These technologies all contribute to improving the surface activity of the implant,increasing the roughness, and promoting bone bonding to a certain extent.Because of the very limited experiments,further investigations are required to explore the optimum technique for the surface treatment of zirconia implants.
