摘　　要：目的:探讨改良Twin-block在治疗非生长发育期关节盘可复性前移位的同时对颌骨生长发育的影响。方法:收集2016年1月~2016年6月就诊于深圳市第二人民医院口腔科,被诊断为颞下颌关节盘可复性前移位,并采取改良Twin-block矫治成功的20~40岁患者26例,分别于治疗前、治疗结束后2个月拍摄头颅定位侧位片,测量治疗前后SNA、SNB、ANB、SN-PP、PP-MP、N-ANS、ANS-Me的变化。使用SPSS19.0软件以配对t检验方法对测量结果进行分析。结果:矫治后ANS-Me增加,且有统计学差异;SNA、SNB、ANB、SN-PP、PPMP、N-ANS治疗前后未见统计学差异。结论:改良Twin-block矫治器在治疗非生长发育期颞下颌关节盘可复性前移位的同时,会少量增加下面高,未见对颌骨生长发育产生其它影响。Objective：To assess the skeletal changes of patients with disc displacement with reduction not in pubertal or pre pubertal stage treated with modified Twin-block by means of lateral cephalometric radiographs.Methods：Twenty-six patients with disc displacement with reduction over 20 years were included in the study.All patients were successfully treated with modified Twin-block.Lateral cephalometric radiographs were taken before and 2months after treatment.Measurements of SNA,SNB,ANB,SN-PP,PP-MP,N-ANS,ANS-Me pre and post were taken.Results：ANS-Me values significantly increased after treatment.There were no significant differences for the indices of SNA,SNB,ANB,SN-PP,PP-MP,N-ANS before and after treatments.Conclusion：Modified Twin-block slightly increases lower facial height of patients over 20 years hisoldy with disc displacement with reduction.No other skeletal changes were found in this study.
