Orthodontic management of a patient with canine displacement associated with an unusual impaction of central incisor. Case report

Abstract

This case report describes the treatment of a nine-year-old female patient with a history of dental trauma at age fi ve in the incisors area. She had an early mixed dentition, class I molar relationships and moderate crowding. The maxillary central incisor had not erupted, so we determined radiographically that it was impacted in a horizontal position toward the midline, the lateral incisor was inclined and the canine mesially displaced with an impaction tendency against the lateral incisor. Orthodontic treatment consisted of the placement of initial 4 x 2 orthodontic fi xed appliances and space opening. The periodontal surgery was performed in two stages. In the fi rst stage the central incisor was surgically exposed. Subsequently in the second stage, the maxillary right deciduous canine was extracted, then periodontal surgery was performed to expose the impacted permanent canine. Finally, we tractioned each tooth into its proper position.Key words: Displacement, canine, incisor, impaction.
