The use of fixed orthopedic functional appliances to treat Class II malocclusions, by mandibular retrusion in adult patients, made it easier the treatment of such malocclusions, when facial and periodontal biotypes allow dental compensation. In this regards, this research study aims at presenting a case report of a 21-year old male subject, presenting bilateral half Class II division 1 malocclusion, mild anterior upper and lower crowding, increased overbite and overjet, horizontal growth pattern and, as the main patient’s complaint, lower anterior crowding and increased overbite. The treatment followed a conservative protocol, with no extractions, using corrective devices associated to the Forsus™ Fatigue Resistant Device, from 3M Unitek. Treatment time was twenty months followed by a 2-year post-treatment follow-up. The short and long-term efficiency of this treatment protocol was confirmed observing the stability of the Class II correction and the overbite and overjet. There were no significant changes in the patient’s face and, consequently, in the skeletal pattern in short and long terms. The patient was satisfied with the results achieved during treatment due to device comfort and, after the completion of treatment, with the stability obtained with treatment.
