What kinds of orthodontic appliances are typically used to correct jaw-growth problems?

Correcting jaw-growth problems is done by the process of dentofacial orthopedics. Some of the more common orthopedic appliances used by orthodontists today that help reduce the upper and lower jaw discrepancy include but not limited to: Headgear: This appliance applies pressure to the upper teeth and upper jaw to guide the rate and direction of upper jaw growth and upper tooth eruption allowing the lower jaw to catch up! The headgear may be removed by the patient and is usually worn 12 to 18 hours per day. Palatal Expansion Appliance: A child's upper jaw may be too narrow for the upper teeth to fit properly with the lower teeth. When this occurs, a palatal expansion appliance can be used to widen the upper jaw to fit better with the lower jaw! Herbst: The Herbst appliance is usually fixed to the upper and lower molar teeth and may not be removed by the patient.  more

Correcting jaw-growth problems is done by the process of dentofacial orthopedics. Some of the more common orthopedic appliances used by orthodontists today that help the length of the upper and lower jaws become more compatible include: Headgear: This appliance applies pressure to the upper teeth and upper jaw to guide the rate and direction of upper jaw growth and upper tooth eruption. The headgear may be removed by the patient and is usually worn 10 to 12 hours per day. Herbst: The Herbst appliance is usually fixed to the upper and lower molar teeth and may not be removed by the patient. By holding the lower jaw forward and influencing jaw growth and tooth positions, the Herbst appliance can help correct severe protrusion of the upper teeth. Bionator: This removable appliance holds the lower jaw forward and guides eruption of the teeth into a more desirable bite while helping the upper and lower jaws to grow in proportion with each other.  more
