摘要: 目的 探讨术前正畸对颞下颌关节关节盘及髁突位置和形态的影响。方法 选择骨性错畸形患者30例,在颞下颌关节磁共振图像上进行测量。通过关节间隙测量,判定髁突位置;通过髁突头长度、宽度和高度测量,判定髁突形态;关节盘位置和形态由直接观察判定,采用SPSS 24.0软件包对所得数据进行统计学分析,比较骨性Ⅰ、Ⅱ和Ⅲ类畸形患者在术前正畸前、后关节盘及髁突位置和形态变化。结果 术前正畸前、后关节间隙和关节间隙指数,髁突头长度、宽度和高度、关节盘前移角及关节盘形态差异均无统计学意义(P>0.05)。结论 术前正畸治疗不会导致骨性错畸形患者关节盘及髁突位置和形态改变。

Abstract: PURPOSE: To investigate the effect of pre-surgical orthodontic treatment on the position and morphology of articular disc and condyle of temporomandibular joint(TMJ). METHODS: Thirty patients with skeletal malocclusion was selected. The measurements were taken on MRI of TMJ. The condylar position was determined by measuring the joint space. The condylar morphology was determined by measuring the length, width and height of condyle head. The position and morphology of articular disc was determined by direct observation. The changes of the position and morphology of articular disc and condyle before and after pre-surgical orthodontic treatment in patients with skeletal Class Ⅰ,Ⅱ and Ⅲ malocclusion were observed and analyzed with SPSS 24.0 software package. RESULTS: There was no significant difference in joint spaces and joint space index, the length, width and height of condyle head, the degree of anterior disc displacement and the morphology of articular disc before and after the pre-surgical orthodontic treatment(P>0.05). CONCLUSIONS: Pre-surgical orthodontic treatment does not cause the change of the position and morphology of articular disc and condyle in patients with skeletal malocclusion.
