BIRBE, Joan. Classic planning in orthognatic surgery. Rev Esp Cirug Oral y Maxilofac [online]. 2014, vol.36, n.3, pp.99-107. ISSN 2173-9161.  https://dx.doi.org/10.1016/j.maxilo.2012.04.007.

Orthognathic surgery is one of the elective surgery most often performed in maxillofacial surgery. Their planning must be thorough, ensuring a degree of precision such that the margin of error is less than 1 mm. The classical method for planning orthognathic surgery was based on a cephalometric made from a teleradiography profile. From here outlines a STO (Surgical Treatment Objectives) allowing imagine and measured in the sagittal direction surgically changes. Concomitantly, the model surgery corroborated the expected changes with the STO. The development of cone-beam CT (CBCT) and its subsequent incorporation into our respective clinics has facilitated the transition from a 2D plan based on conventional radiographs and panoramic radiograph profile, a CBCT-based 3D planning. More than one correct approach and treatment planning for orthognathic surgery patients. Each patient should be planned and treated in a personalized way, according to a set of criteria. Evidence exists adjuvants such as cone beam scanner, scanner guided planning, splints, surgical CAD-CAM, 3D models resin or cranial surgery with robot-assisted navigation can be used to improve surgical outcomes and reduce the surgical risk. This may be especially important in severe deformities with abnormal growth and requiring particularly complex surgical procedures. In addition, endoscopic surgery and robotic-assisted surgery for navigation, are rapidly developing in selected cases may be justified particularly complex. The aim of this paper is to discern when such tools are necessary in orthognathic surgery.
