Abstract

The etiology of Angle’s Class II malocclusion are: 1.maxillary protrusion, 2.mandibular retrusion, 3.combination of both. The therapeutic methods of Angle’s Class II malocclusion with mandibular retrusion by using the functional appliance will correct neuromuscular dysfunction, remodeling of the glenoid fossa and enhancement of condyle growth by anterior positioning of mandible. In this case report will present a patient of Angle’s Class II malocclusion with mandibular retrusion. By using multiple functional appliances during active growth period to improve mandible forward positioned and the maxilla-mandible relation is altered. Then, combined with fixed orthodontic treatment, the convex profile and malocclusion is improved. Esthetics and occlusion correction are achieved.
