Orthodontic management of a complete and an incomplete maxillary canine-first premolar transposition
Abstract:
Maxillary canine and first premolar transposition is a complicated dental anomaly to treat, especially if the clinician's goal is to orthodontically move the canine into its normal position. Early diagnosis with cone-beam computed tomography simplifies the treatment of this pathology. This case report describes a patient with bilateral transposition, one complete and the other incomplete, involving the maxillary canine and the first premolar (Mx.C.1P). The orthodontic treatment involved the correction of both transpositions. In the complete transposition, the traction was mesial and upward to move the canine into a more apical position with a wider dentoalveolar process for easier crown interchange.
