如何对钛种植体进行表面改性，提高钛种植体表面物理性能、化学性能和生物性能一直是国内外学者研究的热点。钛表面阳极氧化技术可增加钛表面氧化膜厚度，增加表面粗糙度，增强耐腐蚀性和抗菌性，使钛表面着色。细胞黏附实验显示，经阳极氧化后的钛表面生物活性提高，骨结合能力增强。根据氧化条件的不同，阳极氧化又可以分为一般阳极氧化、微弧氧化、二氧化钛纳米管的形成。本文将对钛表面阳极氧化的研究进展做一综述。“,”Anodic oxidation is used for the surface treatment of commercial implants to improve their functional (physi-cal, chemical, and biological) properties for clinical success. The anodic oxidation technique on the titanium can increase the thickness of titanium surface oxidation film and the surface roughness, enhance the corrosion resistance and antimicro-bial properties, change the color of titanium surface. Cell adhesion experiments have shown that titanium surface is more bioactive for initial bone bonding after anodic oxidation. According to different oxidation conditions, anodic oxidation can be divided into general anodic oxidation, micro arc oxidation, the formation of titanium dioxide nanotubes. This article re-views the impact of titanium and titanium alloy anodic oxidation technology on dental implant.
