Which age group is primarily associated with growth guidance using functional appliances?

• A. Preadolescents
• B. Adolescents
• C. Adults
• D. Infants

Answer: (B)

Growth guidance with functional appliances relies on leveraging the patient’s ongoing skeletal growth to influence jaw relationships. These appliances work by guiding muscle function to stimulate remodeling and forward growth of the mandible or modulate the maxilla, which requires active growth and unfused sutures. That makes adolescence the ideal window, when growth velocity is highest and the jaws are still responsive. In preadolescents there is some growth potential, but the skeletal changes are less predictable and typically smaller. In adults, growth potential is essentially finished, so skeletal changes are minimal and mainly dental in nature. Infants are far too early for this approach. So, adolescence is the age group most associated with growth guidance using functional appliances.
