We developed a new apparatus to meaesure PPT of masticatory muscles and capsule. In this study, we developed the new apparatus and discussed the accuracy of it. To determine the normal range of PPT in normal subjects, 20 normal subjects were measured their PPT.To evaluate the PPT in TMD patients, 20 TMD subjects were measured their PPT.To evaluate whether or not PPT changes occur in subjects with and without temporomandibular disorders (TMD), 20 normal subjects and 20 TMD patients were measured their PPT.The results obtained as follows :1.The PPT values of superficial masseter, anterior temporalis, and lateral capsule in the female group were significantly lower than those in the male group.2.The normal PPT value of masticatory muscles in Japanese was 2.8-2.9kgf/cm^2 in male, and 1.3-1.8kgf/cm^2 in female.3.There was obvious gender difference in the PPT.4.The PPT values of superficial masseter, anterior temporalis, and lateral capsule in the TMD patient group were lower than those in the control group.2.There was significantly difference between the TMD patient group and the control group in the PPT of lateral capsule.

我们开发了一种新仪器来测量咀嚼肌和囊的 PPT。在这项研究中，我们开发了新设备并讨论了其准确性。为了确定正常受试者 PPT 的正常范围，测量了 20 名正常受试者的 PPT。为了评估 TMD 患者的 PPT，测量了 20 名 TMD 受试者的 PPT。为了评估患有或不患有颞下颌疾病的受试者是否发生 PPT 变化对20名正常人和20名TMD患者进行了PPT测量，得到的结果如下： 1.浅咬肌、颞前肌、外侧囊的PPT值2、日本人咀嚼肌正常PPT值男性为2.8-2.9kgf/cm^2，女性为1.3-1.8kgf/cm^2。3 .PPT存在明显的性别差异。4.TMD患者组浅咬肌、颞前肌、外侧囊的PPT值低于对照组。2.差异有显着性侧囊PPT中TMD患者组与对照组的比较。
