Maxillary Canine-Lateral Incisor Transposition: A Case Report

This case report aims to present the orthodontic treatment of a patient who referred to our clinic with a chief complaint of crowding and who had left lateral canine tranposition at maxilla. In the clinical examinations of the patient; severe crowding, retained deciduous canine tooth and dental Angle Class I relation were detected. In the radiographic examinations, impacted and transposed canine tooth was observed. Skeletal Class I relation (ANB: 2o) was observed in cephalometric analysis. Fixed appliances were used in order have the transposed and unerupted canine tooth to erupt. Initially, lateral tooth was completely moved to the place of the canine and the space was obtained for canine in the arch. Then we began to have canine tooth erupt by fixing surgically eruption appliance to canine tooth. After having had an ideal occlusion and canine eruption, canine tooth was grinded to make it look like a lateral tooth and aesthetic of the gingiva at canine was provided by applying connective tissue graft. As a result of the applied orthodontic treatment, a functional occlusion, ideal overjet and overbite relation, and aesthetic smile were provided. In the treatment planning and for the success of the transposed teeth, tooth's position and the multidisciplinary cooperation play a key role.
