[摘要]在正畸临床治疗过程中，弓丝形态的设计和应用至关重要，其不仅关系到正畸治疗效果，而且对治疗周期、治疗后的稳定性等有着重要影响。不正确的弓丝形态的应用容易造成牙弓、牙槽弓、基骨弓形态的不一致，从而可能引起口颌肌系统功能不协调，容易导致复发。很多学者对怎样确定正确的正畸弓丝形态进行了大量研究，包括寻找适合大多数患者的理想弓形以及适合于个别患者的个体弓形。本文将对标准理想牙弓形态以及个体牙弓形态的拟合理论、应用现状以及优缺点作一综述。[关键词]正畸学；牙弓形态；弓丝；正常

Research progress on the arch form in orthodonticsZhang Lin, Duan Peipei, Chen Yangxi.(Dept. of Orthodontics, West China Hospital of Stomatology, Sichuan University, Chengdu 610041, China)
[Abstract]The size and shape of the arch wire used in orthodontic treatment have considerable implications on the treatment effect, treatment cycle and the stability of the dentition. Using improper arch wire may cause mismatching of shape among dental arch, alveolar arch and basal arch, affecting the equilibrium of teeth between tongue and circumoral muscle forces. This always leads to relapse. Arch form relative to orthodontic therapy has been examined in various studies, including the classic and individual arch wire form. The aim of the article is to give a review on the relevant researches about the combination of the classic and individual arch wire form. The theory, practical applications and problems of these methods are described. ......
