There has always been concern in determining the relationship between orthodontic toothmovement and the consequent biological\ncosts to the periodontium and tooth root. The possibility of evaluating the tooth and bone morphology by CBCT allows more\naccurate analysis of qualitative and quantitative aspects of these processes. This paper presents a case report of a 20-year-old male\npatient with Class III malocclusion and hyperdivergent facial pattern, who was surgically treated. A significant amount of labial\nmovement of mandibular incisors was performed during orthodontic treatment before surgery. CBCT was used for evaluation\nof buccal and lingual bone plates before and after tooth decompensation. The changes in the bone insertion level of maxillary\nand mandibular incisors in the present case encourage a reflection on the treatment protocol in individuals with dentoskeletal\ndiscrepancies.
