Orthognathic surgery without presurgical orthodontics: two clinical cases and literature review

Abstract

The conventional approach in orthodontic surgery treatment of dentofacial anomalies requires a varied period of pre-surgical orthodontic treatment. This presurgical period is considered to be important for adequate surgical treatment and stable results. This period is usually long bothersome for patients because dental decompensation is required and there is consequent deterioration of aesthetics and function. Recently, some authors suggest a surgery-first approach (SFA), one of the treatment choices for Class III and bimaxillary protrusion patients. In this report, we present two first cases of Viet Duc Hospital. The patient benefitted from immediate improvement of the facial profile after surgery, and the results were not compromised. We would like to review the literature on indication and effect of this alternative treatment
