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.
