【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。
[Abstract]:Objective: to investigate the effect of modified Twin-block on maxillary growth and development while treating the reducible anterior displacement of articular disc in non-growth and developing stage.Methods: from January 2016 to June 2016, 26 patients aged 20 to 40 years old who were diagnosed as temporomandibular joint disc reducible anterior displacement from January 2016 to June 2016 were treated with modified Twin-block.Lateral cephalic radiographs were taken 2 months after treatment. The changes of ANS-Me were measured before and after the treatment.The measurement results were analyzed by paired t test with SPSS19.0 software.Results: ANS-Me increased after treatment, and there was no statistical difference before and after treatment.Conclusion: the modified Twin-block appliance can treat the anterior displacement of temporomandibular joint disc at the same time of non-growth and development, but it will increase the lower height slightly, and has no other effect on the growth and development of the mandible.
