本文观察测量并分析了颞下颌关节的形态结构,建立了能较客观反映该关节形态的15项指标的正常值。用3项特征指数,即关节窝指数、关节结节指数和髁突指数,能较好地反映该关节的几何形态,并表达其功能部位的相互关系,以及用频数分布曲线反映其分布规律。本文认为,男性的颞下颌关节显著大于女性,而左、右侧之间,有无咬(牙合)组之间的差别均不显著。本文结果可为该关节的临床研究、病变分析乃至人工颞下颌关节的设计,提供形态学依据。
This paper observed and measured the morphology and structure of the temporomandibular joint and established a normal value that can objectively reflect the 15 indicators of the shape of the joint. Using three characteristic indices, namely, the joint index, the joint nodule index and the condyle index, can better reflect the geometric shape of the joint and express the relationship between the functional parts and the frequency distribution curve reflects its distribution. This article argues that the temporomandibular joint of men is significantly greater than that of women, and there is no significant difference between left and right sides, with or without occlusion. The results of this article may provide morphological evidence for the clinical study of the joint, the analysis of lesions and even the design of artificial temporomandibular joint.
