A retrospective cephalometric study was performed to evaluate the reliability and the validity of various maxillary and mandibular superimposition techniques. In the maxilla, Ricketts' position three and the "best fit" techniques were evaluated. In the mandible, Ricketts' position four and the Björk structural method were studied. All techniques proved to be statistically reproducible and reliable. It could not be determined which technique was most valid since a control, such as implants, was not available in the sample used. Both mandibular techniques yielded comparable descriptive analyses of mandibular dental changes. The maxillary superimposition techniques yielded different descriptions of maxillary dental changes which may be a result of the subjective manipulation required when using the best fit technique. Since none of the approaches appeared to be statistically superior, we recommend positions three and four because of their ease.
进行了一项回顾性头影测量研究，以评估各种上颌和下颌重叠技术的可靠性和有效性。在上颌骨方面，评估了里克茨第三位置法和“最佳拟合”技术。在下颌骨方面，研究了里克茨第四位置法和比约克结构法。所有技术在统计学上都被证明是可重复且可靠的。由于所使用的样本中没有诸如种植体之类的对照物，因此无法确定哪种技术最有效。两种下颌技术对下颌牙齿变化产生了可比的描述性分析。上颌重叠技术对上颌牙齿变化产生了不同的描述，这可能是使用最佳拟合技术时所需主观操作的结果。由于没有一种方法在统计学上表现出优越性，我们推荐第三和第四位置法，因为它们操作简便。
