摘　　要：钛及其合金因优越的机械性能以及生物相容性,被广泛作为牙科种植体、整形外科骨组织修复替代材料等。但因其表面生物惰性,需要进行表面改性以提高成骨性和抗菌性。在众多表面改性技术中,微弧氧化技术因能方便、有效地对种植体表面进行元素掺杂和形貌改性,能极大地提高钛基种植体的生物学性能,逐渐成为热门的种植体表面改性技术。众多学者研究发现,可以通过调整微弧氧化反应的参数以及联合其他表面改性技术,在钛基种植体表面制备具有不同形貌和化学成分的TiO2涂层,提高种植体的成骨性和抗菌性,提高种植成功率。本文针对使用微弧氧化技术制备钛基种植体表面涂层及其成骨性和抗菌性的研究进展进行综述。Titanium and its alloys are widely used as alternative materials for dental implants and bone tissue repair in orthopaedic surgery due to their superior mechanical properties and biocompatibility.However,the surface of these materials is biologically inert and needs to be modified to improve their osteogenic and antibacterial properties.Micro-arc oxidation(MAO)has become a popular surface modification technology because it can conveniently and effectively modify the surface of implants by element doping and morphology.This method can greatly improve the biological properties of titanium-based implants.TiO2 coatings with different morphologies and chemical compositions can be prepared on the surface of titanium-based implants by adjusting the reaction parameters of MAO and combining with other surface modification techniques.This strategy can improve the osteogenic and antibacterial properties of implants and increase the planting success rate.In this paper,the surface coatings of titanium implants prepared by MAO and their osteogenic and antibacterial properties will be reviewed.
