The straightwire appliance, by the refinements of its design, has revolutionized fixed-appliance orthodontics. Treatment is facilitated by the use of many preformed components and the use of unsightly and troublesome auxiliary springs is largely removed. However, the straightwire appliance is a precision instrument and must be used precisely, or the results of treatment will be seriously compromised. This is the first of two articles, in which the design principles and clinical management of the straightwire appliance (in one dental arch only) will be considered.
直丝弓矫治器通过其设计的改进，彻底改变了固定矫治正畸学。许多预制部件的使用便于了治疗，并且很大程度上消除了使用难看且麻烦的辅助弹簧的情况。然而，直丝弓矫治器是一种精密仪器，必须精确使用，否则治疗效果将受到严重影响。这是两篇文章中的第一篇，将探讨直丝弓矫治器（仅在一个牙弓）的设计原理和临床应用。
