摘　　要：背景:在正畸治疗过程中,弓丝是固定矫治器的重要组成部分。而弓丝的选择在很大程度上决定了牙齿排列的效率。其中,镍钛合金由于其具有超弹性和形状记忆效应而广泛应用于固定矫治中,并成为研究热点。目的:综述镍钛弓丝的发展历史及研究现状。方法:利用计算机在PubMed、WebofScience、中国知网中进行文献检索。中文关键词为“正畸,镍钛弓丝”,英文关键词为“Orthodontics,NiTi”,根据纳入与排除标准对文章进行筛选,最终纳入77篇文献进行综述。结果与结论:针对镍钛弓丝的不足之处,许多学者从成分、工艺、表面改性等多个方面进行研究,试图寻求改进方法。但是,目前的成品镍钛弓丝仍然存在着各种各样的弊端,如弓丝的美观性能较差、镍离子的释放可能会产生过敏反应及美学涂层易脱落等问题。虽然目前已有成品镍钛弓丝投入临床使用,但就正畸治疗而言,因其过程的复杂性及许多研究仍处于实验室阶段,尚未出现满足各方面正畸临床治疗需求的理想镍钛弓丝。各类镍钛弓丝的改进是对现有镍钛弓丝的重要补充和发展,并且有望将来在临床应用中发挥巨大作用。BACKGROUND:During orthodontic treatment,the arch wire is an important part of the fixed appliance.The choice of arch wire largely determines the efficiency of tooth alignment.Among them,nickel-titanium alloys are widely used in fixed orthodontics due to their superelasticity and shape memory effect,and have become a research hotspot.OBJECTIVE:To review the development history and research progress of nickel titanium arch wires.METHODS:The literature search was performed in PubMed,Web of Science and CNKI databases.The Chinese and English keywords were"orthodontics,NiTi".The articles were screened acco rding to the inclusion and exclusion criteria.Finally,77 articles were included for review.RESULTS AND CONCLUSION:Many scholars did researches to ove rcome the drawbacks of the NiTi arch wire,such as improving the composition,manufacturing process and surfa ce modification.Howeve r,the current finished nickel-titanium arch wires still have various drawbacks,such as poor aesthetic properties of the arch wires;the release of nickel ions may cause allergic reactions,and the aesthetic coating is easy to fall off.Although there are commercial products of NiTi arch wire and are widely used in clinical orthodontic treatment,due to the complexity of orthodontic process,and many researchers are still in the laboratory stage;there is no ideal NiTi arch wire to meet the needs of all aspects of orthodontic clinical treatment.The improvement of various types of NiTi arch wire is an important supplement and development to the existing NiTi arch wire,and is expected to play a huge role in clinical applications in the future.
