目的:探讨拔除1颗下颌切牙矫治Ⅱ类错的适应证和矫治特点。方法:选取34例拔除1颗下颌切牙治疗效果满意的病例,进行矫治前、后模型测量分析和X线头影测量分析,应用SPSS11.0软件包对数据进行配对t检验。结果:大多数患者治疗前均存在一定程度的Bolton指数不调。矫治后,上前牙弓长度减小,上前牙弓宽度增加;上中切牙角(U1-SN)减小,上、下中切牙夹角(U1-L1)增大,下中切牙角(L1-MP)无明显变化。结论:部分上颌需减数治疗的骨性Ⅱ类错患者,可考虑同时拔除1颗下颌切牙,但要严格选择适应证,注意控制上、下切牙唇倾度,协调好上、下牙弓关系,以获得理想的矫治效果。

China) Abstract PURPOSE:To preliminarily evaluate the surgical treatment results of disc displacement of temporomandibular joint(TMJ).METHODS:From October 2009 to September 2010
9 patients(11 joints) with disc displacement of TMJ(8 females and 1 male
and with an average mouth opening of 21.3mm) underwent disc repositioning and fixation via arthroscopy or open anchorage surgery.All patients were clinically followed up at least 3 months
and MRI examinations were performed at regular intervals.RESULTS:All incisions healed well and there were no severe complications.The average mouth opening increased to 32.8mm and the disc position remained favorable on MRI at the latest follow-up.CONCLUSIONS:With accurate diagnosis and selection of appropriate indications
disc repositioning and fixation via arthroscopy or open anchorage surgery should be used as a treatment of choice for disc displacement of TMJ.Keywords Temporomandibular joint
