The orthognathic surgery is the standard treatment for the correction of dentofacial deformities, in order to get a stable dental occlusion and facial harmony. The advancement of technology and the evolution of the concepts involved in the diagnosis and treatment plan in this area have been immeasurable, leading to the development of new methods, such as computer-aided jaw surgery system by a three-dimensional (3D) virtual surgical planning. The advent of the cone-beam computed tomography (CBCT) allows the acquisition of 3D images of the patient’s craniofacial complex and eliminates the ambiguity that can occur with two-dimensional (2D) images. Surgical simulation in 3D may benefit patients by providing a more accurate treatment plan and streamlined surgery, especially for patients with complex dentofacial deformities. The breakthrough of software tools for the diagnosis and treatment planning allows the construction of 3D surface models, dynamic cephalometry, semi-automatic mirroring in cases of asymmetry, interactive cutting of bone, bony segment repositioning, 3D splint manufacturing, bone reconstruction and visualization and prediction of the changes in hard and soft tissues of the face. The aim of this study was to report a case where the computed-assisted surgical planning predicts the possibility in achieving balance between aesthetic and function. Alterations in the virtual planning allow overcoming obstacles in actual surgery. Considering all possible details, the process provides greater predictability, practicality and precision in surgical planning.
