摘要 背景:口腔正畸用镍钛弓丝临床使用后期常发生弓丝力学性能降低现象,严重影响了临床治疗效果,有研究表明口腔唾液电解质环境腐蚀是影响其性能的主要因素之一。目的:综述近年国内外关于口腔正畸用镍钛弓丝腐蚀性研究的进展。方法:采用计算机检索中国知网数据库CNKI 1995-01/2010-10,PubMed数据库和Elsevier(ScienceDirect)数据库1975-01/2010-10与正畸用镍钛弓丝腐蚀性相关得研究。结果与结论:在复杂的口腔环境中,温度、负载、氟离子等因素均能加速对正畸用镍钛弓丝的腐蚀,不同程度地影响正畸用镍钛弓丝的性能,降低正畸镍钛弓丝的机械性能,增大表面粗糙度进而延长了正畸治疗疗程,增加了正畸治疗成本。正畸用镍钛弓丝腐蚀所释放的镍离子降低了其生物安全性。防腐蚀处理能提高镍钛弓丝的抗腐蚀能力,主要应用表面处理技术,但目前安全有效的方法并不多,对正畸用镍钛弓丝的腐蚀和防腐蚀还有待于进一步深入研究。 BACKGROUND：Orthodontics with nickel-titanium arch wires often occurs the decrease of mechanical property after clinical application,and seriously affects the effect of clinical therapy.Studies show that corrosion in oral electrolyte is one of the most reasons.OBJECTIVE：To review the research progress on nickel-titanium arch wires in orthodontics recently at home and abroad.METHODS：Literatures related to corrosion of nickel-titanium arch wires in orthodontics from CNKI database,PubMed database and Elsevier（ScienceDirect） database were retrieved.RESULTS AND CONCLUSION：In complex oral environment,temperature,load,fluorinion and other factors can accelerate the corrosion of nickel-titanium arch wires,the property of nickel-titanium arch wires in orthodontics was influenced to some extent,and which reduced the mechanical properties of nickel-titanium arch wires in orthodontics,increased the roughness of surface and then prolonged the course of treatment,and increased the cost of orthodontic treatment.The release of nickel ion of nickel-titanium arch wires in orthodontics reduced its biological safety.Anticorrosion treatment can improve the corrosion resistance of nickel-titanium arch wires;surface treatment technology is mainly applied.However,safe and effective method is seldom at present,the corrosion and anticorrosion on nickel-titanium arch wires in orthodontics is needed to be further deeply studied.
