摘　　要：目的　寻求口呼吸所致安Ⅱ1 错畸形患者的有效治疗方法。方法　在2 8例恒牙期口呼吸所致安Ⅱ1 错患者中,有1 6例采用Tip -Edge差动直丝弓技术进行矫治;另外1 2例以快速扩弓联合Tip -Edge技术进行矫治,用图像数字化X线头颅定位摄片仪,作治疗前后X线头影测量对比分析,并进行统计学检验。结果　联合治疗组S -Go增加3.2 1mm ,U6 -PP、L6 -MP分别减小1 .6 3mm和1 .4 2mm ,Yaxis、SN -MP、FH -MP和SN -PP均较治疗前明显减小,与单纯组比较有显著性差异;两个组治疗后的SNB、U1 -L1和Go -Pg及等测量值明显增大,ANB则明显减小,但两组间比较无显著性差异。结论　对口呼吸所致的安Ⅱ1 错患者而言,采用快速上颌扩展联合Tip -Edge差动直丝弓技术进行治疗,更有利于垂直向的控制。Objective To study an effective orthodontic treatment for the AnglesⅡ malocclusion caused by mouth breathing.Methods Twenty-eight patients with AnglesⅡ malocclusion of topical mouth breathing were selected: sixteen cases were treated by Tip-Edge technology and 12 treated by RME of splint and Tip-Edge technology. The cephalometric analysis of two groups was carried out.Results The values of the united group in S-Go increased by 3.21mm. U6-PP and L6-MP decreased by 1.63mm and 1.42mm. Y-axis, SN-MP, FH-MP and SN-PP of the post-treatment were less than the pre-treatment. There was statistic deference between the Tip-Edge and RME united Tip-Edge group; SNB, U1-L1 and Go-Pg of all the cases were bigger than the pretreatment. But ANB was lower significantly than pre-treatment. But there was no statistic differences between the Tip-Edge and RME united Tip-Edge group.Conclusion The RME of splint and Tip-Edge technical can effective treat AnglesⅡ Malocclusion with mouth-breathing, Because it can control vertical growth of the maxilla and mandible.
