THE ROLE OF CBCT IN THE TRACTION OF BILATERAL MAXILLARY IMPACTED CANINES WITH ADJACENT LATERAL INCISORS ROOTS RESORPTED: CASE REPORT

Abstract

Objectives. Adolescent patient treated for bilateral impaction of permanent maxillary canines with adjacent lateral incisors roots resorpted. Methods. M.T., 13 years, male, shows a Class II molar relationship with the persistent of both upper deciduous canines and the unerupted successors. Analysis of CBCT confirms the impaction of maxillary canines and the root resorption of both maxillary lateral incisors. The treatment plan provided an orthodontic-surgical approach for adequate space management in dental arch, evaluation of eruption movements, choice of anchorage device, surgical exposure and application of Quad Helix Canine System and brackets. Results. A functional occlusion with Class II molar relationship was obtained, the impacted maxillary canines were recovered into the arch preserving the lateral incisors. Good intercuspation was achieved and midlines were coincident. Conclusion. 3D images are important to control the eruption movements of impacted canines, orthodontic mechanics and forces. In this clinical case, good esthetic and stable results were obtained. Resorpted lateral incisors were maintained as well as the periodontium.
