A treatment objective of upper molar distalisation may often be required during the correction of a malocclusion. Distalisation is not only indicated for the management of Class II patients, but also for Class III surgery patients who require decompensation in the upper arch if upper incisor retrusion is needed. Unfortunately, most conventional intra-oral devices for non-compliance maxillary molar distalisation experience anchorage loss. A Pendulum type of appliance and a mini-implant-borne distalisation mechanism have been designed which can be inserted at chair-side, without a prior laboratory procedure and immediately after mini-implant placement. For re-activation purposes, a distal screw may be added to the Pendulum B appliance.
在错颌畸形矫治过程中,通常可能需要上颌磨牙远移这一治疗目标。远移不仅适用于安氏II类患者的治疗,对于需要在上颌牙弓进行代偿以实现上前牙后缩的安氏III类手术患者也适用。不幸的是,大多数用于上颌磨牙非依从性远移的传统口腔内装置都会出现支抗丧失的情况。现已设计出一种摆锤式矫治器和一种微型种植体支持的远移装置,它们可以在椅旁插入,无需事先进行实验室制作程序,且在植入微型种植体后即可立即使用。为了便于再次加力,可在摆锤B矫治器上添加一个远移螺钉。
