The influence of a temporarily altered anterior guidance on mandibular movement patterns of tooth-guided and non-guided protrusion was examined in a clinical study on 20 patients, all with complete sets of teeth. Registration and recordings of movements were done with the computer-aided ultrasonic measuring system MT 1602. Based on an average measuring time of 40 min for each patient the main results were as follows: 1. The shape of the anterior guidance strongly influences the horizontal tracings of tooth-guided and non-guided protrusion. In most cases these tracings show a deviation from the mid-sagittal path due to neuromuscular coordination. 2. Insertion of an idealized, symmetrical anterior guidance or a horizontal plateau lessens the mandibular deviation and harmonizes the tooth-guided and non-guided paths. However, the old neuromuscular engrams are not completely erased. 3. Newly formed engrams can be erased much easier than old ones.
在一项针对20名全口牙齿患者的临床研究中，研究了暂时改变前导对牙齿引导和非引导前伸下颌运动模式的影响。使用计算机辅助超声测量系统MT 1602进行运动记录。基于每位患者平均40分钟的测量时间，主要结果如下：1. 前导的形状强烈影响牙齿引导和非引导前伸的水平轨迹。在大多数情况下，由于神经肌肉协调，这些轨迹显示出偏离矢状中线的路径。2. 插入理想化的对称前导或水平平台可减少下颌偏斜，并使牙齿引导和非引导路径协调一致。然而，旧的神经肌肉记忆痕迹并未完全消除。3. 新形成的记忆痕迹比旧的更容易消除。
