Functional appliances are designed to modify growth and are used primarily for those patients with a deficient lower jaw. Success can only be achieved through consistent, full-time wear of the appliance. The Herbst appliance, unlike many other functional appliances, is fixed, or cemented, to the teeth. This means that the Herbst appliance is working 24 hours a day to maximize growth modification
The Herbst is an appliance that is used to correct the bite. In the past, orthodontists used head gear for the same purpose. However, head gear was difficult to wear and depended on patient compliance. The Herbst is cemented onto the teeth and requires little compliance. It allows for adequate range of motion of the jaws and minimally impacts speech. Most patients will find the Herbst appliance surprisingly easy to wear.
Growth modification is most effective during the greatest period of growth for children (9-14 years of age). When it is initially placed, it will move the lower jaw forward into a corrected bite position. In a growing child, the Herbst appliance enhances lower jaw growth, thereby correcting the bite by addressing the source of the malocclusion.
The Herbst appliance is attached to the teeth with 3D custom bands design by 3Shape Appliance Design software that are placed on the first molars. Some appliances may have an expansion screw in the middle of the palate to help widen the jaw. Telescoping bars, or arms, are attached to the outside of the upper and lower 3d custom bands of the appliance.
