摘要
口腔环境是一个pH值变化的复杂环境。口腔环境内多种成分能使正畸镍钛弓丝受腐蚀,使其机械性能和生物相容性发生变化。弓丝成分和表面氧化膜的改良可以提高其抗腐蚀抵抗性。本文就口腔环境内镍钛弓丝的腐蚀、抗腐蚀性及其机制作一综述。
Oral environment is a complex environment of pH value.Nickel-titanium arch wires are easy to be corroded by many factors in oral environment.The corrosion will affect the mechanical characteristics and biocompatibility.The improvement in oxidize layer and composition of nickel-titanium arch wires can increase the property of corrosion resistance.This review focused on the corrosion and corrosion resistance of nickel-titanium arch wises in oral environment.
