【摘要】：目的:应用锥形束CT(CBCT)对青春期安氏Ⅱ类1分类患者的髁突相对于关节窝的矢状向位置进行测量,为Ⅱ类错早期进行下颌前导的功能矫形治疗计划制订提供依据。方法:实验组选用临床无颞下颌关节紊乱症状的青春期安氏Ⅱ类1分类患者40例(男18例,女22例),应用Twin-block功能矫治器进行下颌前导治疗。对照组选用相应年龄阶段骨性安氏I类拥挤、临床无颞下颌关节紊乱症状并存在埋伏阻生牙、需拍摄CBCT的患者44例(男19例,女23例)。2组患者均于治疗前拍摄全头颅CBCT。应用Mimics10.01软件对2组患者关节窝深度、关节窝前壁角度、关节上间隙宽度、关节前间隙宽度及关节后间隙宽度进行测量,应用SPSS15.0软件包对数据进行统计学分析。结果:实验组与对照组患者两侧关节窝深度、关节窝前壁角度、关节上间隙宽度、关节前间隙宽度及关节后间隙宽度均无显著差异(P0.05)。对安氏Ⅱ类1分类及安氏Ⅰ类对照组2组数据进行配对t检验,显示2组间关节窝深度、关节窝前壁角度及关节上间隙宽度无显著差异(P0.05),但关节前间隙宽度及关节后间隙宽度均有显著差异(P0.05)。结论:青春期安氏Ⅱ类1分类患者与安氏I类患者的关节窝深度、关节窝前壁角度、关节上间隙宽度均无显著差异,但关节前间隙宽度明显减小,而关节后间隙宽度明显增大。该结果提示临床医师在青春期安氏Ⅱ类1分类患者功能矫形治疗前,应考虑患者是否存在髁突的前移代偿。
[Abstract]:Objective: to use conical beam CT (CBCT) to measure the sagittal position of the condyle relative to the articular fossa in the 1 Classification patients with class II, and to provide the basis for the formulation of the functional orthopedic treatment plan for the early mandibular preamble. 40 cases (18 males and 22 females) were treated with Twin-block functional appliance for mandibular preamble treatment. The control group selected the I class of osseous anis in the corresponding age stage, no temporomandibular joint disorder symptoms and ambushed impacted teeth, and 44 patients (19 men and 23 women) who needed to shoot CBCT were all photographed before the treatment of the whole head CBCT. application. Mimics10.01 software was used to measure the depth of the joint fossa, the angle of the anterior wall of the articular fossa, the width of the joint space, the width of the anterior space and the width of the posterior space of the joint. The data were statistically analyzed with the SPSS15.0 software package. Results: the depth of the fossa fossa, the angle of the anterior wall of the joint fossa, and the wide joint space of the experimental group and the control group were wide. There was no significant difference between the width of the anterior joint space and the width of the posterior space of the joint (P0.05). 2 groups of data of group II 1 and class I control group were paired t test. There was no significant difference between the 2 groups of joint fossa, the angle of the anterior wall of the articular fossa and the width of the interarticular space (P0.05), but the width of the anterior joint space and the width of the posterior space were all There were significant differences (P0.05). Conclusion: there was no significant difference in the depth of the articular fossa, the angle of the anterior wall of the articular fossa and the width of the interarticular space, but the width of the anterior space of the joint was obviously reduced and the width of the posterior space of the joint increased obviously. The results suggest that the clinicians have 1 Classification of class II in puberty. Before the functional orthodontic treatment, we should consider whether the condylar advancement compensates.
