Class II malocclusion is one of the most common orthodontic discrepancies. It is likely to produce significant aesthetic and social effects and to increase predisposition to dental trauma.1 There are many devices for the treatment of Class II malocclusion; some involve skeletal growth, whereas others have predominant dentoalveolar action.2 A range of orthopaedic methods, including headgear and modern functional appliances, have been shown to be successful in improving skeletal Class II discrepancy and reducing the severity of malocclusion. Such first-phase treatment can facilitate a shorter and simpler second phase of treatment with fixed appliances.3
