ABSTRACT

Functional appliances are widely used in the treatment of growing patients with skeletal Class 2 malocclusions. Many Class 2 cases also require a stage of treatment with fixed appliances preceding or following functional therapy. In order to introduce EVAA functional appliances, discuss its efficiency and the clinical problem encountered two patients having skeletal Class 2 malocclusion mostly due to the retrognathic mandible and treated simultaneously with fixed and EVAA appliances were presented. It seems reasonable to assume that the simultaneous use of fixed and EVAA appliances in the treatment of skeletal Class 2 and dentoalveolar malocclusions is at least as effective as the other functional appliances.
