Mandibular movement during lateral articulatory movements was studied in young subjects with no apparent dental disease or malocclusion. A closed circuit television movement detector was used. Signals of each vector of movement were combined in pairs to provide envelopes of movement in three planes, mutually at right angles. Symmetry of movement was not as common as expected and sudden small changes in direction were frequently observed. Maximum displacement in each vector of movement was not always coincident. It is postulated that treatment factors, such as simple restoration of teeth, are initiating factors which cause variation in mandibular movement from the normal.
在没有明显牙齿疾病或错牙合畸形的年轻受试者中，研究了侧方关节运动时的下颌运动。使用了闭路电视运动探测器。将每个运动向量的信号两两组合，以提供相互成直角的三个平面中的运动包络。运动的对称性并不像预期的那样常见，并且经常观察到方向上的突然小变化。每个运动向量中的最大位移并不总是一致的。据推测，诸如简单的牙齿修复等治疗因素是导致下颌运动偏离正常的起始因素。
