The results of Pancherz analysis shows that the correction of negative overjet is mainly due to the advancement of maxilla and upper incisors. But the position changes of mandible and lower incisors imply that severe maxillary hypoplasia with high angle and/or mandibular retrusion is contraindicated by the method conducted in this study.

头影测量侧位片Pancherz分析法的分析结果表明，本研究中上颌后缩患者反覆盖的矫治主要由上颌骨、上切牙的前移引起的，但下颌骨和下切牙位置的变化提示适应症的选择应注意避免上颌后缩同时伴有高下颌角和／或下颌后缩的患者。
