应用Ｐｈｉｌｉｐ压力测定仪，首次在我国进行颞下颌关节腔内压的测量，结果显示：开口、前伸、对侧侧向运动、咀嚼、吞咽、微笑、讲话及静止状态下，关节压为负值，其中咀嚼运动时负压值最高，平均－１１．８６ｍｍＨｇ。闭口、后退及同侧侧向运动状态下，关节压为正值，其中闭口位时关节压最高，平均＋２．８８ｍｍＨｇ。在静止状态下关节压平均值为－２．８７ｍｍＨｇ。在开口运动中，男性关节压绝对值均较女性高，正常值变动幅度也大于女性，Ｐ＜０．０５。综合统计各种运动状态下关节压平均值为－２．６６ｍｍＨｇ，正常范围在－２２．３～＋６ｍｍＨｇ之间。
The application of Philip pressure gauge for the first time in our country temporomandibular joint cavity pressure measurement showed: open, antegrade, contralateral lateral movement, chewing, swallowing, smiling, talking and resting state, the joint pressure is negative , Which negative pressure during chewing the highest value, with an average of -11.86mmHg. Closed mouth, retreat and ipsilateral lateral motion, joint pressure is positive, which closed the highest bit joint pressure, the average + 2.88mmHg. Mean joint pressure at rest was -2.87 mmHg. In the open movement, the absolute value of male joint pressure than women, the normal range of change is also greater than the female, P <0.05. According to the statistics, the mean value of joint pressure was -2.66mmHg under various exercise states and the normal range was -22.3 ~ + 6mmHg.
