Intraarticular pressure within the superior aspect of the temporomandibular joint was examined during mandibular and masticatory movements It was revealed that the temporomandibular joint had the pumping function. Thus, this function plays an important role in the nutritional exchange between the vascular system and the articular cartilage. In a state of temporomandibular disorders (anterior disc displacement without reduction), however, the pressure buffering ability of the articular disk, which is considered to be the greatest among buffer structures of the temporomandibular joint, is reduced with a consequent increase in intraarticular pressure. Intraarticular pressures increased upon mastication and generally were higher when they were chewing elastic-hard food (kamaboko) than hard (okaki) and soft (rice) food.

在下颌和咀嚼性运动过程中检查了颞下颌关节上部的关节内压，结果表明颞下颌关节具有泵浦功能。因此，此功能在血管系统和关节软骨之间的营养交换中起着重要作用。然而，在颞下颌疾病的状态（前椎间盘位移而不减少），但是，关节盘的压力缓冲能力（被认为是颞下颌关节的缓冲结构中最大的），随之而来的是关节内压的增加。咀嚼时的关节后压力增加，并且在咀嚼弹性 - 耐铁的食物（kamaboko）时通常比硬质（冈崎）和软（大米）食物更高。
