The integration of functional and fixed appliance treatment.

This article describes a functional appliance system to correct Class II problems, which is clipped on to bands, cemented to the teeth. This appliance has several advantages, as the patient cannot remove it. It acts on the teeth and jaws for 24 hours each day, patient co-operation is not a problem, and as a result the treatment time is short. Any fixed appliance system can be added while the functional phase is being completed so allowing full integration of the two treatment systems.
