Abstract : Myofunctional appliance therapy is one of the highly effective modalities of management of class II malocclusion in patients with remaining growth potential. Age, compliance, wear time, and skeletal maturation contribute to a successful outcome. A twin block appliance is beneficial when there is a positive visual treatment objective and a retruded mandible. In this case report, a 13-year-old male patient with a typical class II skeletal pattern was treated with a Twin block appliance followed by fixed orthodontic treatment. Significant soft tissue, dental, and skeletal changes can be achieved with proper case selection and patient compliance.

Keywords : Class II, Myofunctional Appliance, Skeletal Maturation, Twin Block.
