摘要
通过对老年颞下颌关节紊乱综合征(TMJDS)患者在治疗前后,戴与不戴夹板时正中位关节CT扫描的图像分析,发现老年颞下颌关节紊乱综合征患者的髁突不仅在矢状面发生了后移位,而且在水平面双侧髁突水平倾斜角亦呈不对称状态。而夹板对老年TMJDS的矫治作用不仅为适当恢复垂直距离,主要在于消除了干扰,使后移位的髁突调整到关节凹的中位,并且平衡不对称的两侧髁突水平角。作者认为,本方法在颞下颌关节紊乱综合征的诊断及疗效判断方面,参考价值较大。
AbstractThe computed tomography of elderly TMJDS pa-tients treated with and without splint were studied inthree dimensions. The results showed that thecondyle was in a retruded position in the glenoid fossain sagittal dimension and the horizontal condylar an-gle appeared asymmetry in axial dimension. Underthe splint treatment , the retruded condyle can be ad-justed to the center of the glenoid fossa and the hori-zontal condylar angle can be balanced , since the splintmay correct the vertical dimension and eliminate theocclusal interferences. This study indicates that thehorizontal condylar angle can be considered as a sig-nificant factor in diagnosis of TMJDS and evaluationof the outcome of treatment.
