钛及钛合金种植体表面处理的研究进展

钛的优良特性早已被公认为首选牙用种植材料,其表面氧化膜是形成骨结合的关建。为了进一步增加其耐腐蚀性和生物相容性,人们采取了多种方式进行表面处理,最终达到在植入体的不同部位产生不同的粗糙表面,以利于不同细胞在不同地方的附着,增加其生物活性。同时,达到避免各种污染物对纯钛种植体影响的目的。近年来钛种植体材料表面处理已经成为研究热点,本文就表面处理的方法进行综述。

Research Progress of Titanium and Its Alloy Implant Surface Treatment

Titanium has been recognized as the preferred dental implanting materials because of its excellent characteristics, and the oxidation film of its surface is the key point of osseointegration. To further increase its corrosion resistance and biocompatibility, many researchers have adopted a variety of methods to perform surface treatment and ultimately gain different rough surface on the different parts of the implant, facilitating different cells adhere to the different parts of the surface of the implant to increase their biological activity. Meanwhile, it can avoid the effects of various pollutants on titanium implants. In recent years, titanium and its alloy implant surface treatments have attracted much attention. This review briefly summarizes the different methods of surface treatments of titaniumimplants.
