Orthodontic treatment combined with a maxillomandibular advancement (MMA) can be an effective option for patients who need not only corrected occlusion but also facial rejuvenation. In this case series, two patients underwent orthodontic treatment and bimaxillary orthognathic surgery involving MMA, one of them with a counterclockwise rotation of the occlusal plane (OP).
In both cases, the face was rejuvenated, a functional occlusion was established, and the posterior airway space (PAS) was widened.
The facial mask ages three dimensionally. MMA should be offered to patients who have insufficient skeletal projection and are considering improving their facial appearance beyond just correcting a malocclusion problem. The reverse facelift provides more soft-tissue support, resulting in mid- and lower-face rejuvenation.
正畸治疗联合上颌骨前移(MMA)对于不仅需要矫正咬合关系还需要面部年轻化的患者来说是一种有效的选择。在本病例系列中,有两位患者接受了正畸治疗和双颌正颌手术,涉及 MMA,其中一位患者的咬合平面呈逆时针旋转。
在这两种情况下,面部都得到了年轻化,建立了功能咬合,后气道间隙(PAS)得到了拓宽。
面罩会使人的面部在三维上显得衰老。对于那些骨骼突出不足并希望改善面部外观而不仅仅是矫正咬合问题的患者,应该提供 MMA。反向拉皮术提供了更多的软组织支撑,从而实现中下面部年轻化。
