Abstract

Objective: The aim of this case report was to highlight the advantages of cone beam computed tomography (CBCT) imaging over conventional 2D radiographs in providing accurate data related to the localization of impacted maxillary canines and their relation with the adjacent anatomical structures. Case presentation: An initial orthopantomography and a CBCT exam confirmed the impaction in palatal position of the maxillary left canine 2.3 in a 15-year-old female patient. The intraoral exam showed the retention of the temporary canine 6.3. After thoroughly assessing the position of 2.3 and the resorption degree of the lateral incisor 2.2, we decided to extract 6.3, to surgically expose the crown of 2.3 and to use the tunnel traction technique combined with orthodontic braces. To minimize the risk of further root resorption of 2.2, we used light disto-occlusal forces, followed by buccal forces. A follow-up CBCT scan was taken after 10 months of treatment to reassess the position of the impacted canine, using angular and linear measurements. After 18 months of active treatment, the impacted canine was aligned in the dental arch. Conclusions: When compared to conventional 2D radiographs, the use of CBCT imaging offered additional relevant data which positively influenced the treatment planning and the treatment outcome.
