The principles of straight arch technique are described and the mechanical characteristics of contemporary pretorqued, preangulated "straight arch" appliances are summarized. A step wise approach is presented for efficient orthodontic tooth movement using sliding mechanics with .022" straight arch appliances. The steps are: 1) alignment and leveling; 2) molar correction and space closure; 3) finishing. Specific suggestions are made for wires and force elements best suited to sliding mechanics.
阐述了直丝弓技术的原理,并总结了当代预转矩、预成角“直丝弓”矫治器的力学特性。提出了一种使用0.022英寸直丝弓矫治器进行滑动力学矫治的高效正畸牙齿移动的分步方法。步骤如下:1)排齐整平;2)磨牙矫治与间隙关闭;3)精细调整。针对最适合滑动力学的弓丝和加力部件给出了具体建议。
