Objective To explore the clinical application of cone beam CT in the diagnosis of traumatic anterior teeth before orthodontic treatment in order to reduce the risk of orthodontic treatment failure due to adhesion. Methods 48 fixed orthodontic treatment cases with the history of anterior teeth trama were selected. The anterior teeth were examined by CBCT to exclude root and alveolar bone adhesions. Results 3 cases of root-alveolar bone adhesion were found, and the upper anterioa teeth of the remaining 45 cases were successfully moved by orthodontic treatment. Conclusion CBCT examination is recommended to check the periodontal ligament in patients of fixed orthodontic treatment with the history of anterior teeth trauma in order to exclude the root-alveolar bone adhesion cases.
