In all achsiographic techniques a non perpendicular alignment and adjustment of the sagittal-vertical registration plates to the centric positioned hinge axis leads to an incorrect recording of mandibular movements. Among other things the dimension of the registration error decisively depends on the quality and quantity of the angle of hinge axis inclination. The achsiographies of 234 patients were analysed. In most cases incorrect measurements of the individual Bennett angle of only 1-2 degrees were found. These deviations are not relevant and have therefore not to be taken into account. On the other hand differences of the correct and incorrect recorded Bennett angle between 3 degrees and 8 degrees could be registrated in more than 25%. These errors have to be considered in diagnostics and treatment procedures. Correcting methods and techniques are described and discussed.
在所有轴面记录技术中，矢状-垂直记录板与处于中心位置的铰链轴未垂直对齐和调整会导致下颌运动记录错误。除其他因素外，记录误差的大小在很大程度上取决于铰链轴倾斜角度的质量和大小。对234例患者的轴面记录进行了分析。在大多数情况下，发现个体 Bennett 角仅有1-2度的测量错误。这些偏差无关紧要，因此无需考虑。另一方面，超过25% 的情况可以记录到正确和错误记录的 Bennett 角之间存在3度至8度的差异。在诊断和治疗过程中必须考虑这些误差。文中描述并讨论了校正方法和技术。
