The maxilla and mandible give the face its proportions and equilibrium, while remaining indissociable from the skull. The harmony of these structures is established according to two planes of reference: the base of the skull in a relationship of cranio-facial interdependence, the dental arch making the occlusal relationship a decisive factor in the concept of facial equilibrium. This occlusal obligation, criterion of normality and stability, confers all of the originality of orthognatic surgery, which must also take into account the periods of cranio-facial growth and oro-facial functions. The authors describe the modern concept of this surgery, the essential place of orthodontic preparation, and technical innovations such as computer-assisted simulation.
上颌骨和下颌骨赋予面部比例与平衡，同时与颅骨紧密相连、不可分割。这些结构的和谐是依据两个参考平面确立的：在颅面相互依存关系中以颅底为参照，牙弓使咬合关系成为面部平衡概念中的决定性因素。这种咬合要求作为正常与稳定的标准，赋予了正颌外科手术所有的独特性，而正颌外科手术还必须考虑颅面生长阶段和口面部功能。作者们描述了这种手术的现代概念、正畸准备的重要地位以及诸如计算机辅助模拟等技术创新。
