Twin Block Appliance Therapy in the Management of Class II Patients: A Clinical Report

1 modifies anatomy. The challenge of functional therapy is to maximize the genetic potential of growth and guide the growing face and developing dentition towards a pattern of optimal development. Functional appliance therapy aims to improve the functional relationship of dentofacial structures by eliminating unfavourable developmental factors and improving the muscle environment enveloping the developing occlusion through alteration of the position of the teeth and supporting tissues; A new functional behaviour pattern or engram is established that can support a new position of equilibrium. Functional appliances harness the natural forces of the orofacial musculature and transmit these to teeth and alveolar bone through the medium of the appliance. These appliances modify growth to intercept and
