What is the primary purpose of functional appliances?

Explanation:
Functional appliances are designed to influence jaw growth by altering muscle function and bite posture, so they can encourage forward development of the mandible in growing patients. They target skeletal Class II problems where the mandible is retrusive, making use of the adolescent growth spurt to guide overall jaw development rather than just moving teeth. While dental changes occur as a side effect, the primary aim is skeletal modification to improve the bite, not tooth extraction, whitening, or replacing a fixed appliance. In adults, the growth potential is largely exhausted, so the skeletal effect is limited and the appliances mainly produce dentoalveolar adjustments.
