| 摘 要： | 目的：评价应用MBT直丝弓矫治技术矫治安氏Ⅱ类Ⅰ分类错[牙合]的临床效果。方法：应用MBT直丝弓矫治技术对36例安氏Ⅱ类Ⅰ分类患者，通过拔除4颗双尖牙或2颗上颌双尖牙矫治，对治疗前后X线头影测量结果进行统计及分析。结果：应用MBT直丝弓矫治技术矫治后，前牙覆盖减小6．04mm（P〈0．01），上中切牙倾斜度（U1-NA）减小15．43度（P〈0．01），上中切牙突度U1-NA（mm）减小4、71mm（P〈0、01），ANB明显减小（P〈0．05）、结论：MBT直丝弓矫治技术是治疗安氏Ⅱ类Ⅰ分类错[牙合]患者是一种操作简单，有效的方法。

| Abstract: | OBJECTIVE: To evaluate the therapeutic effects of MBT straight wire on extraction case of Class II division I. METHODS: Thirty-six class II division I malocclusion patients were treated with MBT straight wire by extracting 4 bicuspid premolars or 2 maxillary bicuspid premolars. The X-ray cephalograms were analyzed before and after the treatment of MBT straight wire. RESULTS: After the treatment, the overjet was reduced by 6.04 mm (P < 0.01); U1-NA was reduced by 15.43 degrees (P <0.01); and U1-NA (mm) was reduced by 4.71 mm (P <0.01). ANB was significantly reduced (P < 0.05). CONCLUSION: MBT straight wire not only shortens the operation but also shows superior effect for Class II division I malocclusion cases. |
