1、正畸治疗牙周病所致前牙移位的临床可行性分析［摘要］目的：分析止畸修复治疗牙周病所致前牙移位的可行性。方法：取才周病所致前才移位患者60例作为本次研究对象，患者均接受正畸修复治疗，观察、比较患者治疗前后牙周袋深度、前牙间牙槽骨高度、前牙覆盖、前牙覆牙合、探诊出血率及中颌骨间和牙间的角度差值。结果:患者治疗前后的牙槽骨高度和颌凸角、下颌平面角、牙合平面角、Y轴角、下中切牙与下颌的平面角、中颌骨间和牙间的角度差值的比较，差异无统计学意义（卩＞0.05）；而治疗后的牙周袋深度、前牙覆盖、前牙覆牙合、探诊出血率以及面角、上下齿槽座角、上下中切牙夹角、上屮切牙凸距等观察指标均治
2、疗前改善，差异有统计学意义（P〈0.05）。结论：正畸治疗牙周病所致前牙移位，可内收前牙，矫正唇倾、下颌后缩，对改善和保持牙齿外表美观、恢复口腔止常生理功能、控制牙周炎有积极作用。［关键词］牙周病；前牙移位；正畸治疗；可行性［中图分类号JR783.5［文献标志码］A［文章编号11008-6455（2015）18-0055-03ClinicalfeasibilityanalysisoforthodonticstreatmentfortheshiftofthefrontteethduetoperiodontaldiseaseNIEJin-ping（DeparLinent
