Esthetic analysis of the face in some patients presenting a dental Class II can reveal the need for maxillo-mandibular advancement surgery. In these cases, mandibular advancement alone would provide a result which was satisfactory from the occlusal viewpoint but esthetically displeasing. Using bi-maxillary advancement, the impact of nasal volume is reduced and the nasolabial relationship is corrected. The sub-mandibular length is increased, thus creating a better-defined cervico-mental angle. This treatment technique involving a prior mandibular procedure has the advantage of restoring patients' dental occlusion while optimizing their facial esthetics.
对一些患有II类牙列的患者进行面部美学分析，可能会发现需要进行上颌-下颌前徙手术。在这些病例中，仅下颌前徙从咬合角度来看会产生令人满意的结果，但在美学上却不尽人意。采用双颌前徙可减少鼻腔容积的影响并矫正鼻唇关系。下颌下长度增加，从而形成更明显的颈-颏角。这种先进行下颌手术的治疗技术具有在优化患者面部美学的同时恢复其牙列咬合的优点。
