The female patient, 16 years and 8 months old, had as main complaint mandibular retrognathism. In the clinical examination, convex profile, buccal upper incisors, increased overbite and overjet, retrognathic mandible, and Class II division 1 malocclusion were verified. MPA was used simultaneously with the MEAW technique for Class II camouflage. At the end of the treatment, an improvement in facial profile, occlusion with normal overbite and overjet, and good intercuspation were obtained. MPA and the MEAW technique demonstrated effectiveness in orthodontic camouflage of Class II division 1 malocclusion with mandibular retrognathism.
