The purposes of the study were to compare the relationship of anterior guidance with condylar movement and to analyze the three-dimensional relationship of canine guidance and the working condylar path. The mandibular movements of ten subjects with normal dentitions and no observable temporomandibular joint abnormalities were recorded using an electronic mandibular measuring system capable of measuring six degrees of freedom. Measurements were made employing both canine and clutch guidance. The data were collated and evaluated making use of mathematical modeling techniques. It was shown that the movements of the working condyle were affected by anterior guidance. When canine guidance is not consistent with the working condylar path, there is a sagittal displacement of the working path created to compensate for the lack in harmony.
本研究的目的是比较前导与髁突运动之间的关系，并分析尖牙引导与工作侧髁突运动轨迹的三维关系。使用能够测量六个自由度的电子下颌测量系统，记录了10名牙列正常且无明显颞下颌关节异常受试者的下颌运动。测量时采用了尖牙引导和咬合引导。利用数学建模技术对数据进行整理和评估。结果表明，工作侧髁突的运动受前导的影响。当尖牙引导与工作侧髁突运动轨迹不一致时，会产生工作侧运动轨迹的矢状位移，以弥补协调性的不足。
