The Herbst appliance is used to correct skeletal imbalances where the lower jaw is behind the upper jaw (overbite). This correction occurs due to a combined restriction of upper jaw growth and an enhancement of lower jaw growth. The Herbst is used when the overbite is more severe and skeletal in nature.
The Herbst appliance has orthodontic bands that are cemented to the upper and lower molars. The appliance connects the upper and lower jaws with rods and tubes that position the lower jaw forward into a normal position.
In order to achieve the desired change in the skeletal pattern, the Herbst appliance is worn for one year. After the Herbst appliance is removed, you will either go straight into braces or wear a retainer at night until the rest of your permanent teeth erupt.
