Single-phase treatment started during late mixed dentition using functional followed by fixed appliance therapy has proven to be the most effective approach to achieve correction of Class II malocclusion. This case report demonstrates the use of this treatment approach in an 11-year-old girl with skeletal and dental Class II malocclusion, large overjet, deep overbite, increased incisor exposure and a gummy smile. She was given a functional appliance for 1 year which was immediately followed by fixed mechanotherapy for final finishing and detailing of the occlusion. The magnitude of skeletal and dental correction achieved, along with the dramatic improvement in facial appearance of the patient, provides a strong case for establishing the efficacy of this treatment modality.
