Orthodontic Appliances

Herbst Appliance

HerbstThe Herbst Appliance is a non-removable functional appliance which effectively corrects skeletal Class II malocclusions. The Herbst design utilizes a buccal rod and tube assembly to encourage the patient's jaw to function in a forward advanced position. The tube and rods extend from the maxillary first molar area down to the mandibular first bicuspid region.

Super Screw

The Super Screw expander is used in situations that require a larger degree of arch development but a physically smaller screw is desired. A 12mm or 16mm screw can be requested. A special adjustment wrench is used with each appliance.


Sometimes a patient's upper jaw needs to be enlarged. In such cases, Dr. Epps may widen the upper jaw with a Palate Divider or RPE. This device spreads the halves of the upper jaw apart. New bone then fills in between the two halves and the upper jaw remains permanently wider. The device has a center screw that must be turned with a key. The key is inserted into the key hole in the center screw and then gently pushed toward the back of the mouth one notch. How often you turn the key will depend on the patient's specific case.

The first noticeable effect of the divider is that the front teeth begin to separate. This is a sign that the appliance is working properly. The space will close naturally when the key turning is stopped.

Thumb/Finger Appliance



Tongue Thrusting Appliance


Dr. Epps prefers to correct tongue thrusting by giving patients a tongue thrusting appliance. This appliance, similar to a mouthguard, is usually worn at night. Other times, a more permanent appliance is prescribed and can be only be adjusted by Dr. Epps.
