A 3 dimensional process of recording the human mandible movements. Our system belongs to a general process made by the C.N.E.S. (Centre National d'Etudes Spatiales) in Toulouse; it records and measures the movements of body and limbs of spacemen. A test of this process is adapted for movements of mandible. The system uses a various instrumentation: two electronic cameras; infrared rays; reflectors; a multiplexor case; a magnetoscope; a dimultiplexor; a computer; two screens of control. Four reflectors are fixed on the face of subject; two others are fixed on a metallic system that is glued on the buccal face of inferior canines. These reflectors record the specific movements of mandible. Usual mastication and mastication on one side in turn are recorded in a young man with his natural teeth. Some graphs are showed for example. A data processing system measures the trajectory of mandible in the three dimensions of space, according to time and rapidity of movement. This video data processing seems to be a good method to analyze movements of mandible and mastication.
一种记录人类下颌运动的三维过程。我们的系统属于法国国家空间研究中心（位于图卢兹）所开展的一个常规项目；它用于记录和测量宇航员身体及四肢的运动。此过程经过调整后用于下颌运动测试。该系统使用了多种仪器设备：两台电子摄像机、红外线、反射器、一个多路复用器箱、一台磁强计、一个双路复用器、一台计算机以及两个控制屏幕。四个反射器固定在受试者面部；另外两个固定在粘贴于下颌尖牙颊面的金属装置上。这些反射器记录下颌的特定运动。对一名拥有天然牙列的年轻男性依次进行正常咀嚼和单侧咀嚼的情况进行了记录。例如，展示了一些图表。一个数据处理系统根据运动的时间和速度来测量下颌在三维空间中的轨迹。这种视频数据处理似乎是分析下颌运动和咀嚼的一种良好方法。
