Forty-six subjects were examined using the HDI and a PRI. Two sets of pantographic tracings were used to determine if subjects experiencing dysfunction could differentiate between degrees of dysfunction. Subjects were divided into groups according to their clinical symptoms: none (D0), sligh (D1), and moderate dysfunction (D5). Each subject was further classified into one of two groups according to his state of occlusion/articulation. The PRI detected differences between the group with moderate dysfunction and those groups with no dysfunction and slight dysfunction on the basis of differences between the first and second sets of tracings; no difference was found between the groups with slight and moderate dysfunction. Subjects with poor occlusions had higher PRI scores. The diagnosis of TMJ dysfunction may require the use of several modalities such as subjective responses, clinical examination, radiographs, and pantographic tracings.
46名受试者接受了高密度阻抗成像（HDI）和姿势恢复指数（PRI）检查。使用两组下颌运动描记图来确定功能障碍受试者是否能够区分不同程度的功能障碍。受试者根据临床症状分为几组：无功能障碍（D0）、轻度功能障碍（D1）和中度功能障碍（D5）。根据受试者的咬合/关节状态，每位受试者进一步分为两组中的一组。姿势恢复指数根据第一组和第二组描记图之间的差异，检测出中度功能障碍组与无功能障碍组和轻度功能障碍组之间的差异；轻度功能障碍组和中度功能障碍组之间未发现差异。咬合不良的受试者姿势恢复指数得分更高。颞下颌关节功能障碍的诊断可能需要使用多种方式，如主观反应、临床检查、X光片和下颌运动描记图。
