摘要: [摘要] 目的 对微种植体支抗和多曲方丝弓技术分别矫治Ⅲ类错牙合产生的上气道变化进行对比研究,分析两种技术带来的气道变化差异。方法 选取12例利用微种植体推下颌牙列向后矫治Ⅲ类错牙合的病例,同时选取13例采用多曲方丝弓技术矫治Ⅲ类错牙合的病例,测量所有病例治疗前后X线头颅侧位片的上气道数据,对两种技术治疗前后上气道差值作对比统计学分析。结果 两种技术矫治Ⅲ类错牙合,上气道只在LPW有差别,其余几项的比较无统计学差异。结论 在矫治Ⅲ类错牙合时,微种植体支抗推下颌牙列向后使下咽气道减小。

Abstract: Objective To compare the different effects between micro-implant and MEAW technique on the upper airway dimensions in patients with class III malocclusion. Methods 12 patients were selected to distalize the lower dentition with the micro-implant,while 13 patients were treated with MEAW technique. The cephalometric radiographs of the pre- and post-treatment upper airway in two groups were measured ,then the comparision of those changes was statistically analyzed . Results There were statistically differences in LPW (P<0.05), but other comparison had no statistically significance. Conclusion The LPW is decreased using the micro-implant technique in patients with class III malocclusion.

Key words: Micro-implant, MEAW, upper airway , class III malocclusion
