Abstract

Early treatment of Class II division 1 malocclusion using functional appliance not only corrects the skeletal disproportion by altering growth pattern but also creates a significant improvement of the facial profile which enhances the patient’s self-esteem. Moreover, functional appliance therapy enables treatment of such cases by non-extraction approach rather than by extractions. The aim of this paper was to present a case report describing the treatment of a young male patient with retruded mandible using a removable functional appliance called the ‘Twin Block’ for growth modification and correction of the increased overjet followed by pre-adjusted edgewise appliance. Successful results were obtained with improvement in facial profile and correction of Class II malocclusion.
