Aim: The present case report describes the orthodontic treatment of a patient with a missing maxillary right central incisor and a skeletal Class III jaw relationship due to a retrognathic maxilla. Materials and
Methods: Treatment was conducted in two phases, with a removable appliance and Delaire’s facemask used in the first phase and a fixed appliance used in the second phase. Mesial movement of the maxillary canine, first premolar, second premolar and first molar was achieved sequentially over the two phases of treatment. After 36 months, the anterior space was closed, and good intercuspation and interproximal contacts and satisfactory root parallelism were achieved. Finally, interproximal spaces were closed orthodontically, the crown of the upper right lateral incisor was anatomically modified to imitate a central incisor, the right maxillary canine was reshaped slightly along the incisal edge, and a gingivectomy was performed in the maxillary canine area to achieve normal vertical crown proportions.
Results: Post-treatment intraoral photographs show satisfactory dental alignment and acceptable overjet and overbite. The patient was satisfied with her teeth and profile.
Conclusion: The combination of maxillary protractor and fixed appliance successfully corrected the skeletal Class III malocclusion and achieved forward mesial movement of the maxillary posterior teeth.
