目的：研究正畸治疗产生的前牙覆合覆盖的改变是否对上气道有影响。方法收集正畸治疗前后覆合覆盖改变较大的病例，对其上气道形态进行测量、对比及相关性分析。结果治疗前的覆合与覆盖之间无相关性，覆盖与上气道各个指标间的相关性无统计学意义，而覆合与舌骨-下颌平面距离、后鼻棘-咽顶点距离、腭咽：McNamara线、悬雍垂尖-中咽壁距离有相关性。治疗后的覆盖与覆合、舌骨-眶下点水平距离（H-Or）、后鼻棘-悬雍垂顶点距离有相关性。治疗后的覆合仅与覆盖、H-Or有相关性。结论治疗前的覆盖与上气道的形态无相关。正畸治疗后产生的覆合覆盖变化对部分气道形态有一定的影响。

Objective To study the influences of orthodontic correction of deep overbite or overjet on the morphology of upper airway . Methods 28 patients with significant change of overbite and overjet during orthodontic treatment were included in this study . Some measurements of the upper airway mor-phology were done and correlation analysis was used to evaluate the change . Results Before orthodontic treatment ,there was no correlation between overbite and overjet ,and no correlation between overjet and upper airway measurements . But the overbite showed statistical correlation with H-M P ,AD-PNS ,Mc1-Mc2 ,U-M PW . After orthodontic treatment ,the overjet showed correlation with the overbite ,H-Or and PNS-U . Overbite only showed correlation with the overjet and H-Or . Conclusions The overjet before orthodontic treatment was not correlative with the morphology of upper airway . The changes of the over-bite or overjet had some effect on the morphology of upper airway after orthodontic treatment .
