Principal articulator of not only speech and swallowing, but also masticatory system, that helps to prepare the food bolus. Positions and movements of tongue affect the denture stability. The significant function of tongue was reported in the Journal "Quintessence International". Dynamic measurement of tongue shape was developed using an ultrasonic and CCD camera systems. The system was consisted of 3.5 MHz transducer of which beam scans the sector area of 90 degrees angle along dorsum at 30 times a second and a detector. To obtain the relative position of the probe to the head, markets attached to the probe and glasses were detected using CCD camera simultaneously during the ultrasonic measurement. The palate was impressed by a dental impression material and the casts are poured. A palatal prosthesis was fabricated. Both CCD camera image and tongue image signals were imposed in an image signal using audio-visual mixer and the signal was digitized by a computer. The tongue and palatal shapes at a desired time were superimposed with an image processing software after adjusting the movements of head and probe. The tongue shape to the palate was measured at rest position of occlusion and increase of vertical dimension. The anterior portion of tongue was coherent to the anterior palatal contour at rest position. The tongue was positioned to the post-downward at the increase of vertical dimension with the decrease of curvance of tongue contour.The above system and findings were reported in the Journal of Japan Prosthodontic Society. As next step of this study influence of the aging on the change of tongue shape and tongue function will be investigated.

不仅是言语和吞咽的主要发音器官，也是咀嚼系统的主要发音器官，有助于准备食物。舌头的位置和运动会影响义齿的稳定性。 《Quintessence International》杂志报道了舌头的重要功能。使用超声波和 CCD 摄像系统开发了舌头形状的动态测量。该系统由 3.5 MHz 传感器和探测器组成，该传感器的光束以每秒 30 次的速度沿背部扫描 90 度角的扇形区域。为了获得探头与头部的相对位置，在超声波测量过程中，使用 CCD 摄像头同时检测探头和眼镜上附着的市场。用牙科印模材料在上颚上留下印痕，然后浇注铸件。制作了腭假体。使用视听混合器将CCD相机图像和舌头图像信号强加在图像信号中，并通过计算机将信号数字化。调整头部和探头的运动后，用图像处理软件叠加所需时间的舌头和腭的形状。在咬合静止位置和垂直尺寸增加时测量舌头相对上颚的形状。静止位置时，舌的前部与前腭轮廓一致。随着垂直尺寸的增加，舌头轮廓的曲率减小，舌头被定位到后下方。上述系统和研究结果发表在日本修复学会杂志上。作为本研究的下一步，我们将研究衰老对舌头形状和舌头功能变化的影响。
