Defining the location of the dental midline is critical for oral esthetics in camouflage orthodontic treatment of facial asymmetry

Abstract

When considering camouflage orthodontic treatment of a malocclusion associated with significant facial asymmetry, it is important to define the location of the dental midline. The patient, a 19-year-old Japanese woman, had an anterior open bite and a dental midline discrepancy associated with facial asymmetry. A nonsurgical treatment plan was considered. The main treatment objective was to correct the anterior open bite and the dental midlines in both arches. The dental midline discrepancy was eliminated, and proper overjet and overbite were achieved. Although the facial asymmetry remained, oral esthetics dramatically improved and a favorable occlusion was obtained. The results suggest that appropriately defining the location of the dental midline is critical for successful camouflage treatment of facial asymmetry.
