Functional or Growth Modifying Appliances at O’Keeffe Orthodontics, Waterford
Functional appliances are orthodontic devices used to modify facial growth and improve the facial profile in growing children. Twin Block Herbst appliances are commonly used to encourage lower jaw growth for example where the lower jaw is deficient.
They are worn full time for a period of approximately 6-12 months and are normally followed by fixed appliances.
