Therefore, is of great importance the patient’ understanding of the treatment outcome.
Social and psychological concerns, improved function, appearance, and self-esteem can encourage a patient to pursue surgery. Quality of life has been found to improve for the patients who underwent surgery because of increased self-esteem and confidence. Improvement in appearance is associated with improvement in psychosocial adjustment. Major changes in facial appearance appear to be readily integrated into the individual’s self-concept. Those who choose surgical correction of a dentofacial deformity tend to regard their dentofacial deformity as more severe than do those patients with similar problems that have decided against surgical treatment and are undergoing orthodontics only. Patients’ concern before treatment appears to be self -consciousness regarding their facial body image. Motivation for treatment affecting facial esthetics is related to psychological and social factors. Improvement in appearance is an important motivation for patients to seek orthognathic treatment. Patient’s decision to undergo orthognathic surgery is based on several needs and motives. Important factors in the selection of orthognathic surgical procedures and treatment plan are the stability of the results, the predictability of hard and soft tissue changes to achieve facial balance and the patient’s response. The selection of the appropriate procedure must be based on the clinician’s anticipated objectives with regard to esthetics, function, and stability, but also on the patient’s objectives, expectations, and perceived needs. The differential diagnosis process generates a problem list and treatment planning options to discuss with the patient. The indication for surgical-orthodontic treatment is that a skeletal or dentoalveolar deformity is so severe that the magnitude of the problem lies outside the envelope of possible correction by orthodontics alone. The skeletal component of the malocclusion of these patients cannot be corrected without orthognathic surgery. The advances in orthognathic surgery, computer imaging, rigid internal fixation, and shorter hospital stays, made surgery a realistic option for many patients. Over the past decade a growing number of adult patients are seeking orthodontic treatment. The aim of this article is to present and discuss the different methods of cephalometric prediction of the orthognathic surgery outcome. Today, three-dimensional prediction methods are available, such as three-dimensional computerized tomography (3DCT), 3D magnetic resonance imaging (3DMRI) and surface scan/cone-beam CT.

Both manual and computerized cephalometric prediction methods are two-dimensional and cannot fully describe three-dimensional phenomena.

Cephalometric prediction in orthognathic surgery can be done manually or by computers, using several currently available software programs, alone or in combination with video images. Traditionally cephalometry has been employed manually nowadays computerized cephalometric systems are very popular. Cephalometrics is a routine part of the diagnosis and treatment planning process and also allows the clinician to evaluate changes following orthognathic surgery. The predicted results must be presented to the patients prior to treatment in order to assess the treatment’s feasibility, optimize case management and increase patient understanding and acceptance of the recommended treatment. The prediction of orthognathic treatment outcome is an important part of orthognathic planning and the process of patient’ inform consent. Surgical and orthodontic techniques have developed to the point where combined orthodontic and surgical treatment is now feasible to manage dentofacial deformity problems very satisfactorily. Over the past decade the growing number of adult patients seeking for orthodontic treatment made orthognathic surgery popular.
