The positive reception of the primary edition of Essentials of Orthognathic Surgery was gratifying and may probably be ascribed to its concise and to-the-point approach. We have been treatment planning facial esthetics three dimensionally (3D) for as long as we have been performing orthodontics and orthognathic surgery. The treatment planning for these patients was than assessed on the basis of the classical cephalometric analysis integrated with the data we got from our new “Vertical Planning Line” analysis, considering the soft tissue changes occurring after orthognathic surgery (soft/hard tissue ratio) using the following formula for each soft tissue landmark: Orthognathic surgery combines orthodontic treatment with surgery of the jaw to correct or establish a stable functional balance between the teeth, jaws and facial structures.
