The reproducibility of the condylar reference position was examined at the pont of unstrained hinging movement of the mandible in subjects with TMJ symptoms and in asymptomatic subjects. Three different operators performed the procedure to detect interoperator variability. Each operator made five registrations using computerized axiography in the electronic mandibular position indicator mode. Data were evaluated by an analysis of variance using three factors: (1) repetitions of the single operator, (2) data from symptomatic versus asymptomatic patients, and (3) values of different operators. The results showed that none of these factors had a significant influence on reproducibility of the condylar reference position. High reproducibility was obtained in both symptomatic and asymptomatic groups. Measured values remained within +/- 0.1 mm in 58.6% and within +/- 0.2 mm in 24.3% of the registrations.
在有颞下颌关节症状的受试者和无症状受试者中，在下颌骨无约束铰链运动点处检查髁突参考位置的可重复性。三名不同的操作人员进行该程序以检测操作者间的变异性。每位操作人员使用电子下颌位置指示器模式下的计算机化轴描记法进行五次记录。数据通过方差分析进行评估，使用三个因素：（1）单个操作者的重复次数，（2）有症状与无症状患者的数据，以及（3）不同操作者的值。结果表明，这些因素均对髁突参考位置的可重复性没有显著影响。有症状和无症状组均获得了高可重复性。在58.6%的记录中测量值保持在±0.1mm以内，在24.3%的记录中保持在±0.2mm以内。
