摘要: 目的 研究微种植体支抗辅助矫治Ⅲ类错牙〖KG-*3〗合时,远中整体移动下颌牙列对上气道的影响。 方法 选择12例需要远中移动下颌牙列的Ⅲ类患者,在下颌植入微种植体支抗,利用微种植体远中移动下颌牙列,测量治疗前后X线头影的上气道大小以及牙颌角度,并作统计分析。 结果 上气道舌根后的咽腔径(PAS)、下咽腔的矢状径(LPW)、鼻咽腔的矢状径(UPW)变小,并且PAS变化明显,L1-MP变小,SNA略有变大,其余变化无统计学意义。 结论 利用微种植体支抗远中整体移动下颌牙列矫治Ⅲ类错牙合时,会导致舌后气道变小。

Abstract: Objective To investigate the effect of distalization of the lower dentition using the microimplant 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. The cephalometric radiographs of the pre and posttreatment upper airway and dental changes were measured and statistically analyzed. Results There were statistically significant reductions in LPW,UPW and especially PAS. Meanwhile, obvious decreasing of L1-MP and slightly increasing of SNA were found. Other changes had no statistically significant differences. Conclusion The treatment of distalizing the lower dentition by using microimplant leads to the narrowness of upper airway, mainly in PAS area.
