Abstract: Class II malocclusion is one of the most common orthodontic problems and it affects one - third of patients seeking orthodontic treatment. It can be due to prognathic maxilla, retrognathic mandible or both. Twin Block is a well - accepted patient friendly functional appliance for the treatment of growing patients with Class II malocclusion due to mandibular retrognathism. It works by guiding the mandible forward through the inclined plane on the bite block. It alters the neuromuscular environment and promotes favourable growth of the mandible by condylar adaptation. This case report describes the comprehensive management of a 11 - year - old female patient diagnosed with a severe Class II skeletal discrepancy and Class II div I malocclusion with retrognathic mandible. Treatment was carried out in 2 stages. Stage I included twin block for mandibular advancement, reducing the overjet, achieve Class I molar relationships and gain anchorage at the start of treatment to simplify the fixed appliance stage. Stage II treatment included preadjusted edgewise appliance therapy for the aligning and levelling of the dentition. The post - treatment results were highly satisfactory, showing improvement in dental, skeletal and soft tissue profile.
