Orthodontic Appliances

Rapid Palatal Expander

ExpanderAttached to the upper molars through bonding or by cemented bands, the Rapid Palatal Expander is an orthodontic device used to create a wider space in the upper jaw. It is typically used when the upper jaw is too narrow for the lower jaw or when the upper teeth are crowded or blocked out of the dental arch.

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, 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

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.

Even though the Herbst appliance prevents the lower jaw from moving backward, opening and closing movement still occur easily, and patients do not have any problems learning to chew their food with their lower jaw in this new position.

As with all kinds of braces, patients with Herbst appliances need to be careful about what they eat. For instance, cold foods such as ice slushes, Popsicles and ice will freeze the cement and make the brace loosen. 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.

Space Maintainers

If one of the four upper front teeth is lost early, the space will stay open on its own until the permanent tooth comes in.

A space maintainer is made of stainless steel and/or plastic. Some space maintainers are removable, which fixed space maintainers are cemented into the patient’s mouth.

PowerScope

PowerScope is a wire-to-wire device used in class II corrections that delivers ultimate patient comfort, eliminates the need for headgear tubes and can be used with either banded or bonded molar tubes. It is simple, efficient and designed with your comfort in mind.

Distal Jet

The Distal Jet Appliance uses a solid track wire and two sets of locking screws on each side. The appliance is self-limiting by design because it has a distal stop attached to the tracking wire. The Distal Jet can be converted to a Nance Appliance by tightening the distal and anterior locks against the track wire and adding a Nance holding arch.

Bionator

A bionator appliance is a removable appliance used to stimulate growth changes in the lower jaw that cannot be accomplished with braces. This appliance works naturally, activating the appliance each time the patient talks, swallows and open and closes their mouth. So it constantly exerts light pressure on the dental arches and teeth moving the jaws into their proper place.

Bite Plate

In situations where the teeth overlap to such a degree that the edges of the lower front teeth actually bite into the hard palate, orthodontists recommend the bite plate appliance, a removable device that looks like a conventional retainer in most cases. A bite plate appliance is worn full-time (except when eating and brushing) for six months to a year.

Correcting a deep bite as early as possible will favorably affect long-term stability and eliminate unnecessary pain, discomfort, ulcers, etc. When growth is modified while a person is still growing, the change becomes more permanent. One of the first things to relapse in a finished orthodontic case is the overbite. Thus, correcting a severe overbite is one of the first important corrections that needs to be made while growth is still occurring.

Nance Appliance

nance-appliance.jpgThe Nance Appliance is used to prevent upper molars from rotating or moving forward after you’ve worn a headgear or any other appliance to move your molars back. Some patients wear the Nance Appliance while they are awaiting their bicuspids to grow into place.

This appliance is made of two bands that are cemented onto the first molars and a wire spans the roof of the mouth from one molar to the other. An acrylic pad or “button” covers the wire that touches the roof of your mouth directly behind your front teeth.

Patients should always brush around the bands daily. Do not eat sticky, chewy candy as it can loosen your appliance. If you have any problems with your Nance Appliance, please call our office immediately.
