RESUMO
This case report describes the successful orthodontic treatment for a healthy woman with maxillary canine-premolar transposition associated with rare hypodontia of the contralateral canine. The treatment included extraction of the transposed maxillary right and deciduous maxillary left canines and 2 mandibular second premolars. The objectives of the treatment were to (1) correct the upper midline deviation and the occlusal plane cant, (2) move the maxillary first premolars into the canine position, (3) retract the mandibular incisors to improve the facial profile, and (4) reduce the labial protrusion. Orthodontic treatment was carried out with the lingual technique in the maxillary arch and esthetic ceramic brackets in the mandibular arch. The segmented mechanics were effective, fast, and consistently promoted the necessary movement without side effects. The smile line was improved, resulting in an ideal and esthetic gingival exposition, with the borders of the maxillary teeth following the lower lip smile curvature. The patient achieved ideal dentofacial esthetics, achieved better dental and functional occlusion, was pleased with her improved facial contour, and as a result, showed an improved self-image.

Dentofacial deformities usually are surgically treated, and 3D virtual planning has been used to favor accurate outcomes. Cases reported in the present article show that orthognathic surgery carried out to correct facial asymmetries does not comprise only one treatment protocol. 3D virtual planning might be used for surgical planning, but it should also be used to diagnose the deformity, thus allowing for an analysis of the best-recommended possibilities for the orthodontic preparation that suits each individual case.

Cases reported in the present article show that orthognathic surgery carried out to correct facial asymmetries does not comprise only one treatment protocol. 3D virtual planning might be used for surgical planning, but it should also be used to diagnose the deformity, thus allowing for an analysis of the best-recommended possibilities for the orthodontic preparation that suits each individual case.
RESUMO As deformidades dentofaciais são, geralmente, tratadas de forma cirúrgica, e o planejamento virtual 3D tem sido utilizado para aumentar a precisão dos resultados. Os casos exemplificados no presente artigo mostram que a cirurgia ortognática para correção das assimetrias faciais não apresenta um único protocolo de tratamento. O planejamento virtual 3D pode ser adotado para planejar a cirurgia, mas também deve ser utilizado na fase de diagnóstico da deformidade, assim permitindo uma análise das possibilidades mais indicadas para o preparo ortodôntico mais adequado em cada caso.
