The final purpose of this research is to establish a standard for diagnosis of TMJ sound. TMJ clicking patients were investigated by using a jaw function analyzing system. The results were as follows.1.Clickings were classified into two types, the first one is the type which clicking occurred at the constant condylar position, the other at the various positions. 2.There was a correlation between the condylar translation velocity and the magnitude of TMJ sound (peak sound pressure level). 3.According as peak sound pressure level increased, mean power frequency sifted higher range in almost patients. 4.Among the diagnostic parameters on the six degrees of freedom jaw movement, the velocity and acceleration parameter had high diagnostic value for clicking.The correlation between intercuspal position-retruded contact position distances (ICP-RCP distances) and condylar positions in TMJ tomography were studied in 100 TMD patients. Results were as follows.1.The average of ICP-RCP distance of TMD patients was 0.34mm (normal subject 0.9mm). 2.Shorter ICP-RCP distances tended to coincide with posterior condylar displacement.Finally, six degrees of freedom jaw movement data, acoustic analysis of TMJ sound, electromyogram, occlusal diagnosis, TMJ image of MRI or Tomography, chinical sign and symptom should by estimated totally to establish a good standard for TMJ sound diagnosis.

本研究的最终目的是建立颞下颌关节声音的诊断标准。使用颌功能分析系统对颞下颌关节咔哒声患者进行了研究。结果如下： 1.咔嗒声分为两种类型，第一种是在髁突恒定位置发生的类型，另一种是在不同位置发生的类型。 2.髁突平移速度与TMJ声音大小（峰值声压级）存在相关性。 3.随着峰值声压级的增加，几乎所有患者的平均功率频率都筛选到更高的范围。 4.下颌六自由度运动的诊断参数中，速度和加速度参数对咔嗒声具有较高的诊断价值。对100例TMD患者进行了TMJ断层扫描中牙尖间位置-后退接触位置距离（ICP-RCP距离）与髁突位置的相关性研究。结果如下：1.TMD患者ICP-RCP距离平均为0.34mm(正常人0.9mm)。 2.较短的ICP-RCP距离往往与后髁位移一致。最后，应综合评估六自由度颌运动数据、TMJ声音的声学分析、肌电图、咬合诊断、MRI或断层扫描的TMJ图像、临床体征和症状，以建立良好的TMJ声音诊断标准。
