目的　研究山羊颞下颌关节上腔内压在5种运动状态下的变化规律。方法　采用Mingograf7型多道生理记录仪对15只健康成年雌性山羊颞下颌关节测量在休息位、小开口位、大开口位、咀嚼及侧向运动时关节内压的值。结果　在休息位时,颞下颌关节上腔内压为负值,开口过程中负压值下降,在咀嚼、侧向运动等周期性运动中,关节上腔内压处于负压与正压交替的周期性变化中。结论　关节上腔内压可用于反映颞下颌关节的功能运动状态。

Objective To study the variation of intracavitary pressure of temporomandibular joint in goats under five kinds of exercise conditions. Methods The Mingograf7 multi-channel physiological recorder was used to measure the intra-articular pressure of 15 healthy adult female goats from the temporomandibular joint at rest, small open mouth, large open mouth, chewing and lateral movement. Results At the resting position, the temporomandibular joint pressure was negative and the negative pressure decreased during the opening. During the period of masturbation and lateral movement, the intra-articular pressure was in negative pressure and positive pressure Cyclical changes. Conclusion The intra-articular pressure can be used to reflect the functional movement of temporomandibular joint.
