Abstract

This case report describes the orthodontic treatment of a boy, aged 15.3 years, with permanent dentition, mesofacial typology, affected with a severe sagittal skeletal Class II division 2 malocclusion, due to a mandibular retrusion. His chief compliant was the position of the maxillary incisors, displaced too palatally, and an impaired facial profile. Herbst and multi-bracket straightwire fixed appliances, together with a custom made modified transpalatal arch (i.e. TPA proclination spring), were used to correct the sagittal discrepancy and to improve the attractiveness of the impaired facial profile.

Keywords: : Class II division 2, Skeletal sagittal discrepancy, functional therapy.
