Functional appliances have been used for decades in correcting skeletal Class II malocclusion in growing patients. This two phase therapy of growth modification and subsequent fixed orthodontic treatment is an accepted procedure with certain advantages like-better esthetics, ability to modify growth, fewer extractions, reduction in duration and difficulty of subsequent therapy, reduce if not eliminate the need for future surgery and reduction in trauma to flared incisors. Twin block appliance designed by Clark has been widely accepted. It brings about correction of saggital discrepancy by skeletal changes and dentoalveolar compensation. As with any removable appliance compliance was a major concern in patients at the peak of or close to the end of pubertal growth spurt. Fixed twin block was designed to overcome these limitations. The clinical effectiveness of fixed twin block in correcting skeletal Class II malocclusion will be illustrated by three case presentations. Key words- fixed, twin block, growth, class II malocclusion
