Functional Appliances
Sometimes the jaws may not align properly, with the lower jaw being deficient. In this case a functional appliance may be ideal.
Functional appliances posture the lower jaw forward and accelerate its growth to a more normal size. They also retract protruding upper teeth to a proper angulation.
Functional appliances are thus perfect for young growing children about 10-12 years of age with a large overjet or horizontal overlap of the teeth.
