The reproducibility of the positional relationship of mandible models in the Dentatus Articulator was studied. Based on the method of A.G. Lauritzen, the articulator is oriented on a hinge axis. The registration procedure was carried out by two subjects on three patients (5 times each). The deviations in the hinge axis point against a value of zero (initial measurement) were then determined with a face-bow. TMJ and SAM face-bows were used for these controls. The deviations from the mean value of the hinge axis point determined in the articulator were within the range of +/- 3 mm in the sagittal and vertical directions. The results tend to indicate that experience, routine, and knowledge of the varioius possibilities of error are necessary if the registration is to be accurate.
研究了下颌模型在牙合架中位置关系的可重复性。基于A.G.劳里岑的方法，将牙合架定向于铰链轴上。由两名受试者对三名患者进行配准程序（每人每次5次）。然后用面弓确定铰链轴点相对于零值（初始测量值）的偏差。使用颞下颌关节（TMJ）面弓和SAM面弓进行这些对照。在矢状面和垂直方向上，牙合架中确定的铰链轴点与平均值的偏差在±3毫米范围内。结果倾向于表明，如果要进行准确的配准，经验、常规操作以及对各种误差可能性的了解是必要的。
