Japanese NiTi superelastic coils, exerting 100 gm of force, were compressed against the maxillary first molars and moved the molars distally 1 to 1.5 mm/month. Anchorage was obtained with a modified Nance appliance cemented onto the first premolars in conjunction with a fixed appliance.
日本镍钛超弹性螺旋弹簧施加100克的力,抵在上颌第一磨牙上,使磨牙每月远中移动1至1.5毫米。通过将改良的Nance矫治器粘结在第一前磨牙上并结合固定矫治器来获得支抗。
