摘要：

背景：侯录等研发的颊侧多曲簧矫治器是一种新型的可全天戴用的矫治器，主要用于乳、替牙期安氏Ⅲ类错牙合畸形，利用颊侧多曲簧柔和的弹力在推上颌骨向前促进其发育的同时，抑制下颌的过度向前发育，形成颌间Ⅲ类矫形力，引起颞下颌关节产生适应性改建，并使下颌功能性后退，解除反牙合。
目的：观察颊侧多曲簧活动矫治器矫治早期安氏Ⅲ类错牙合前后颞下颌关节间隙测量值的变化。
方法：选择功能性或骨性下颌前突的安氏Ⅲ类错牙合患者20例，其中男7例，女13例。初诊年龄5~13岁，平均年龄8.5岁。拍摄颊侧多曲簧活动矫治器矫治前后的颞下颌关节闭口位X射线片，测量颞下颌关节间隙。
结果与结论：矫治后患儿颞下颌关节间隙发生改变，关节前间隙增大、后间隙减小，髁突明显后移位，髁突位置基本正常。说明颊侧多曲簧矫治器适当的持续加力作用，能引起颞下颌关节适应性改建，髁突前移，不会对颞下颌关节产生不利的影响。

Abstract:

BACKGROUND: The buccal multiloop removable appliance designed by Hou et al is new-type appliance for class Ⅲ malocclusion.
OBJECTIVE: To investigate the cephalometry analysis of temporomandibular joint (TMJ) space changes before and after the treatment with a buccal multiloop removable appliance in the early stage of class Ⅲ malocclusion.
METHODS: Twenty early stage of class Ⅲ malocclusion cases, including 7 males and 13 females, aged 5-13 years, 8.5 years in average, were chosen and the cephalometric analysis was performed. X-ray pictures were done to explain the changes in TMJ space before and after treatment.
RESULTS AND CONCLUSION: The left and right linear percentages were changed before and after treatment, respectively. The left and right N/M was changed before and after treatment, respectively. Meanwhile, A and P changes could be achieved in combined treated group. All the findings indicated that the modified fixed the buccal multiloop removable appliance can lead to the reconstruction of TMJ. Meanwhile, suitable continuous orthodontic force does not lead to temporomandibular disorders.
