Abstract

Esthetic analysis of the face in some patients presenting a dental Class II can reveal the need for maxillo-mandibular advancement surgery. In these cases, mandibular advancement alone would provide a result which was satisfactory from the occlusal viewpoint but esthetically displeasing. Using bi-maxillary advancement, the impact of nasal volume is reduced and the nasolabial relationship is corrected. The sub-mandibular length is increased, thus creating a better-defined cervico-mental angle. This treatment technique involving a prior mandibular procedure has the advantage of restoring patients' dental occlusion while optimizing their facial esthetics.

Keywords: Bi-maxillary surgery; Jaws; Orthognathics; Plastic surgery.
