舌头通过与硬腭接触，在咀嚼和吞咽中发挥着重要作用。我们使用带有 7 个压力传感器的实验腭板，并使用下颌运动描记法记录下颌运动，通过测量舌头对硬腭的压力，评估了健康受试者在整个咀嚼固体序列期间舌头和下颌运动的协调性。舌压在咬合阶段出现，在张开开始时达到峰值，并在张开时消失。在每次咀嚼动作中，7 个压力传感器都可以看到舌头压力的顺序、持续时间和大小的特定模式。咀嚼后期（吞咽前8次）的幅度和持续时间明显大于咀嚼早期（开始咀嚼后至8次）。描述了咀嚼过程中舌头接触硬腭、舌头活动的控制以及与下颌运动的协调的正常模式。
The tongue plays an important role in mastication and swallowing by its contact with the hard palate. Using an experimental palatal plate with 7 pressure sensors, and recording jaw movement using mandibular kinesiography, we assessed, in healthy subjects, the coordination of tongue and jaw movements during the entire masticatory sequence of solids, by measuring tongue pressure against the hard palate. Tongue pressure appeared during the occlusal phase, reached a peak near the start of opening, and disappeared during opening. Specific patterns in order, duration, and magnitude of tongue pressure were seen at the 7 pressure sensors in each chewing stroke. Magnitude and duration were significantly larger in the late stage of chewing (8 strokes before initial swallowing) than in the early stage (until 8 strokes after starting mastication). The normal pattern of tongue contact against the hard palate, control of tongue activity, and coordination with jaw movement during mastication is described.
