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.

我们开发了一种新的设备，以刺激咀嚼肌肉和胶囊的PPT。在这项研究中，我们开发了新的设备，并讨论了它的准确性。为了确定正常受试者中PPT的正常范围，测量了20个正常受试者的PPT。为了评估TMD患者的PPT，测量了20个TMD受试者的PPT。评估PPT在患有和没有颞下颌疾病的受试者中是否发生PPT变化是否发生，有或没有颞下颌疾病（TMD）（TMD），20个正常受试者和20个TMD的PPT。颞叶和女性组的外侧囊显着低于男性组。2。男性咀嚼肌的正常PPT值为2.8-2.9kgf/cm^2的男性为2.8-2.9kgf/cm^2，女性的1.3-1.8kgf/cm^2在女性中为1.3-1.8kgf/cm^2。3。ppt.4. ppt.4. ppt.4. ppt ppt.4。组低于对照组中的组。2。TMD患者组与侧囊PPT中的对照组之间存在显着差异。
