To summarize, the principles and the application of an apparatus have been described which without appreciable physical restraint provides graphic representations of the movements of a point on the mandible in three conventional anatomic planes-sagittal, coronal, and horizontal. The apparatus also provides data which permit an estimation of the magnitude and direction of movement of a point on the jaw during function in relation to time. This information prepares the way for the calculation of the path of the selected point in space, as well as its mean velocity and acceleration.
综上所述，已对一种仪器的原理及应用进行了描述。该仪器在没有明显物理约束的情况下，能在矢状面、冠状面和水平面这三个传统解剖平面上，提供下颌骨上某一点运动的图形表示。该仪器还能提供数据，从而可以估计下颌骨上某一点在功能活动期间相对于时间的运动幅度和方向。这些信息为计算所选点在空间中的路径及其平均速度和加速度铺平了道路。
