Series of four open-close, protrusive and lateral movements were recorded by the six degrees of freedom jaw movement recording system OKAS-3D in 20 healthy subjects. Consequently the movement paths of nine condylar points, the palpated lateral pole and eight points located on a square parallel to the sagittal plane with an edge of 10 mm and centred around the lateral pole were calculated. For all movements except the protrusive movements, the 3-D excursions of the condylar points strongly depended upon the choice of condylar reference point (ANOVA, P < 0.001). During laterotrusive movements the Bennett angle and the Bennett shift also varied significantly according to the position of the reference point (ANOVA, P < 0.001). The results of this study underline that comparison of condylar movements between different studies is only possible when the same condylar reference point is used. General consensus on the choice of condylar reference point is thus needed.
通过OKAS - 3D六自由度颌运动记录系统，对20名健康受试者进行了一系列四次开闭、前伸和侧方运动的记录。随后计算了九个髁突点、触诊的外侧极以及位于与矢状面平行的正方形上、边长为10毫米且以外侧极为中心的八个点的运动轨迹。除前伸运动外，对于所有运动，髁突点的三维偏移强烈依赖于髁突参考点的选择（方差分析，P < 0.001）。在侧方前伸运动期间，Bennett角和Bennett移位也根据参考点的位置而有显著变化（方差分析，P < 0.001）。本研究结果强调，只有当使用相同的髁突参考点时，不同研究之间的髁突运动比较才是可行的。因此，需要就髁突参考点的选择达成普遍共识。
