FUNCTIONAL APPLIANCES ARE REMOVABLE APPLIANCES
WHICH ARE MADE FROM ACRYLIC (PLASTIC) AND WIRE.
Essentially Functional Appliances harness the action of the jaw muscles and make use of the growth of the jaws to correct certain bite discrepancies. These appliances need to be worn all the time (day and night) to work effectively thus requiring a high degree of patient cooperation. As these appliances rely on jaw growth they are often implemented at an early age and are not suitable for older patients. After the active treatment is complete they are usually worn at night only to allow time for the teeth to settle into the new position.
Functional Appliances are usually followed up with Braces and may reduce the amount of time braces are needed.
Functional appliances are not suitable for everyone.
