Canine transposition as an alternative to trauma of the maxillary incisors: case report

María Salcedo Lara et al. Dental Press J Orthod. .

Abstract
in English, Portuguese

Objective: The present article aims at reporting the clinical case of a patient who suffered trauma at two years of age, causing almost complete apical displacement of the deciduous maxillary left central incisor and of the permanent incisor.

Methods: Ectopia secondary to intrusion was minimized by surgical removal of the ectopic tooth, and the left permanent canine was submitted to orthodontic traction to replace the extracted tooth.

Results: The treatment period lasted 36 months, resulting in correct occlusion and a good aesthetic outcome.

Conclusions: Dental transposition carried out by means of orthopedic traction is a good alternative in cases of a very unfavorable ectopic tooth position.

Objetivo:: o presente relato de caso descreve uma paciente que sofreu trauma aos dois anos de idade, causando deslocamento apical quase completo do incisivo central esquerdo decíduo e do incisivo permanente.

Métodos:: a ectopia resultante da intrusão foi minimizada pela remoção cirúrgica do dente ectópico, e o canino permanente esquerdo foi tracionado ortodonticamente para substituir o dente extraído.

Resultados:: o período de tratamento durou 36 meses, obtendo-se uma oclusão correta e um bom resultado estético.

Conclusões:: a transposição dentária realizada através da tração ortopédica é uma boa alternativa em casos de dentes ectópicos em posições muito desfavoráveis.
