Within the limits of this study and when using pantographic instruments for research, the following conclusions can be drawn. Mechanical errors in the graphic tracings can result when the posterior vertical styli do not move with the mandible and are not zeroed in relationship to the terminal hinge axis. The errors were significant at the 0.035 level for the following variables: (1) an increase in the vertical dimension, up to 6 mm, (2) a change in the angle of the styli and/or of the tables relative to each other, up to 30 degrees, and (3) an increase in the distance between the posterior horizontal tables. If conclusions are to be drawn directly from tracings in research of mandibular movements, the recording styli should be orientated in relation to the terminal hinge axis and should move with the mandible.
在本研究范围内，当使用全景描记仪进行研究时，可以得出以下结论。当后部垂直描记针不随下颌骨移动且未相对于终末铰链轴归零校准，图形描记中会出现机械误差。对于以下变量，在0.035水平时误差显著：(1)垂直维度增加，可达6毫米；(2)描记针与工作台之间的相对角度变化，可达30度；(3)后部水平工作台之间的距离增加。如果要直接从下颌运动研究的描记中得出结论，记录描记针应相对于终末铰链轴定向并随下颌骨移动。
