摘要： 目的: 研究种植钉辅助上颌快速扩弓联合前牵治疗上颌骨水平向及矢状向发育不足的疗效。方法: 选取上颌骨水平向及矢状向发育不足患者20例[男11,女9例,年龄(11.7±1.0)岁]。收集患者治疗前、扩弓结束、前牵结束、治疗结束时的CBCT,测量各治疗阶段反映颌骨水平向、矢状向、软组织侧貌的指标,分析探究颌骨及软组织侧貌的变化。结果: 上颌骨基骨及基骨弓宽度在治疗后明显增加,下颌骨基骨弓宽度治疗前后无统计学差异。A-Nperp、A-Sperp、Wits、SNA°、FH-NA°在治疗过程中逐渐增大。鼻下点-零子午线变大,颏前点-零子午线、下唇-TVL、颏前点-TVL变小。结论: 种植钉辅助上颌快速扩弓联合前牵能有效治疗上颌骨水平向及矢状向发育不足,并改善侧貌美观。

Abstract: Objective: To investigate the efficacy of miniscrew-assisted rapid maxillary expansion combined with anterior traction in treating horizontal and sagittal underdevelopment of the maxilla. Methods: A total of 20 patients [11 males and 9 females, age (11.7±1.0) years] with maxillary horizontal and sagittal hypoplasia were selected. CBCT was collected before treatment, at the end of arch expansion, at the end of anterior extension, and at the end of treatment. The indicators reflecting jaw horizontal orientation, sagittal orientation, and soft tissue profile were measured at each treatment stage, and the changes of jaw bone and soft tissue profile were analyzed and explored. Results: The width of maxillary basal bone and basal bone arch increased significantly after treatment. There was no significant difference in the width of mandibular basal arch before and after treatment. A-Nperp, A-Sperp, Wits, SNA°, and FH-NA° increased gradually during treatment. The subnasal point-zero meridian became larger, and the premental point-zero meridian, the lower lip -TVL, and the premental point -TVL became smaller. Conclusion: Miniscrew-assisted rapid maxillary expansion combined with anterior traction can effectively treat maxillary horizontal and sagittal hypoplasia, and the side appearance was improved.
