Abstract
In patients with skeletal Class III malocclusion and insufficient maxillary incisal display, maxillary total arch extrusion can be considered as one of the camouflage treatments to improve the smile and profile esthetics as well as the mandibular prognathism. This case report describes the use of MARPE (micro-implant assisted rapid palatal expansion) and maxillary total arch extrusion to treat a patient with skeletal Class III malocclusion who had transverse discrepancy and insufficient maxillary incisal display. The goal of the procedure was to improve the patient’s occlusion as well as facial esthetic. The maxillary removable anterior bite plate, mandibular posterior mini-implants, and vertical elastics were applied to attain the therapeutic goal. The improvement of the occlusal relationship and an esthetic smile were achieved through maxillary total arch extrusion and clockwise rotation of the mandible.
