Palatal Expander
This appliance is used to widen the upper jaw if it is too narrow or create additional space so no permanent teeth will need to be moved. It is attached to the upper 6-year molars with bands and extends across the roof of the mouth.
When patients are still growing, their connective tissue between the left and right halves of their upper jaw is very responsive to expansion. By simply activating the expander through turning a screw in the center of the palatal expander, with a special key we provide, gradual outward pressure is placed on the left and right halves of the upper jaw. This pressure causes an increased amount of bone to grow between the right and left halves of the jaw, ultimately resulting in an increased width.
Herbst Appliance
One of the most common problems orthodontics treat is the discrepancy that occurs when the upper teeth protrude beyond the lower. Ordinarily, when we see a patient with the upper teeth protruding, we tend to think that the upper jaw and teeth are too far forward; but, more often than not, this condition is due to a small lower jaw that is further back than it should be. With these patients, we would like to encourage the lower jaw to catch up in growth, and braces like the Herbst appliance help this happen.
The Herbst is a jaw corrector, used in the growing patient for the correction of protrusive upper front teeth. It is attached to the upper and lower 6-year molars and works by stimulating lower jaw growth and slowing upper jaw growth. This replaces the old dreaded headgear.
As with all kinds of braces, patients with Herbst appliances need to be careful about what they eat. Sticky foods such as caramels, bubble gum and candy suckers will pull the brace away from the teeth. Hard foods like crisp vegetables and hard candies will bend and loosen the Herbst appliance, too. So stay away from these foods during your orthodontic treatment.
Your Herbst appliance will be checked and adjusted at your appointments. If, sometimes between appointments, you develop some sore areas on the inside of your cheeks, please do not try to adjust the appliance yourself. Call for an appointment so that the necessary adjustments can be made.
Wearing an Herbst Appliance
At first, your mouth will feel unusually full and speaking will be awkward. But if you practice reading aloud, your ordinary speech will return quickly. You may also notice more saliva than normal, but this will decrease as you become accustomed to the appliance.
