INTRODUCTION: Functional appliances are an effective way of treating skeletal Class II malocclusion in children and adolescents. A 12 month step-wise mandibular advancement protocol has been proved to enhance the condylar growth and improve the mandibular prognathism using Herbst appliance. OBJECTIVES: The following case report documented a 11 year-old Chinese girl with 11 mm overjet treated by a Phase I 12-month growth modification therapy using Twin Block appliance with Hyrax palatal expander and high pull headgear in a step-wise mandibular advancement protocol followed by a Phase II preadjusted Edgewise appliance therapy. This is one of the cases submitted for the Membership of Orthodontics Examination of the Royal College of Surgeons of Edinburgh.
