Combined orthodontic and surgical management of maxillary deficiency with a Class III profile has accomplished efficient treatment and predictable results. Also, orthodontic/orthopedic therapy can give good results; but, in any case, if one of either or a combined therapy is selected, the orthodontist has to be sure of the correct diagnosis. The cephalometric analyses have to be done with care as it is possible to find contradictions among different analyses, especially in the A/P aspect. The Wits appraisal shows good capacity for determining the antero-posterior maxillomandibular relationship because it is sensitive to the osseous dimensional variants and lower anterior facial height. Nevertheless, it is a supplementary evaluation requiring additional data for the localization of the deformity.
对Ⅲ类错颌上颌骨发育不足进行正畸与外科联合治疗已取得了有效的治疗效果和可预测的结果。此外，正畸/正颌治疗也能取得良好效果；但无论选择哪种治疗方式或联合治疗，正畸医生都必须确保诊断正确。进行头影测量分析时必须谨慎，因为不同分析之间可能会发现矛盾之处，尤其是在前后方向上。Wits评估在确定上下颌前后关系方面能力良好，因为它对骨尺寸变异和下颌前部面部高度敏感。然而，它是一种补充评估，需要额外的数据来定位畸形。
