Fixed- functional appliance therapy using flex developer in a skeletal class II patient

Abstract

A properly selected functional appliance can achieve optimal results in a Class II patient. A removable functional appliance can advance the mandible, but requires excellent patient compliance. Moreover, it can cause intermittent condylar displacement and consequent glenoid fossa remodeling. In contrast, fixed functional appliances have been shown to produce remarkable changes in the glenoid fossa-condyle complex.
