Abstract
Aim of this study [it’s not a study] was to see the effect of twin block appliance. Twin block appliance from its inception and evolution itself has been widely accepted as a more competent Class II corrector compared to earlier bulky monoblock appliances. Functional appliances can be used successfully in growing patients with certain skeletal Class II patients. It is dependent on patient’s compliance. It also simplified the fixed appliance phase. In this case report a 11-year-old girl was treated with twin block appliance. The design of appliance and treatment results were demonstrated in following case report. With proper case selection and good patient cooperation, good appliance construction we can obtain a significant result with twin block appliance. The correction was due to dentoalveolar change, but some was due to favourable skeletal change. Early treatment with the twin-block appliance is effective in reducing overjet and severity of malocclusion.
