Rapid Palatal Expander

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.


Temporary Anchorage Devices (TADs)

One of the many important advances in orthodontics has been the development of temporary anchorage devices, or TADs. Made of a bio-compatible titanium alloy, TADs are mini-screw anchors which are inserted into specific places in the mouth to be used as a fixed point from which teeth can move. Before TADs, orthodontists who wanted to move some teeth while keeping others still, or to achieve orthodontic movement in a mouth with missing teeth, had to rely on headgear for their fixed point. But TADs now provide an option for that fixed point that is smaller, more discrete, more efficient and requires significantly less work for the patient.

Temporary anchorage devices may not be recommended for everyone, and in fact, anchorage devices at all may not be needed in all cases. Contact us if you'd like to know more about TADs and how they can potentially prevent you from needing orthodontic headgear.


Space Maintainers

A Fixed Lingual Arch acts as a space maintainer to keep the molars from drifting forward, and prevent them from blocking the space where permanent teeth will eventually erupt. This appliance is commonly used in cases of premature loss of baby tooth or when the lower teeth of a growing child are slightly crowded and no permanent teeth are extracted to correct the problem.

You should expect soreness the first day or two, and it may hurt to chew. We recommend a soft diet initially. You may take Advil or Tylenol to relieve the pain. Avoid sticky or hard foods, and please monitor how many foods you eat that are high in sugar.

Brushing and flossing daily is very important. Be sure to clean around the bands that are connected to the molars and the wire on the tongue side. This will prevent the formation of cavities or infection of the gums.

The duration of wear varies. We will monitor the eruption of new teeth and make adjustments. Generally, the Fixed Lingual Arch is removed following the eruption of all the permanent teeth.

Trans-Palatal Arch
A Trans-Palatal Arch is an orthodontic appliance used to maintain the upper jaw's arch width and move molars into positions that wires alone can't. The appliance is banded around the first molars on each side of the mouth, and a thin wire spans across the roof of the mouth.

Patients should be sure to brush their appliance daily. Also, avoid sticky, chewy or hard foods as these can get caught between the appliance and the roof of your mouth. These foods may also break the Trans-Palatal Arch.

Band & Loop
A Band & Loop is a fixed space maintainer used to hold space for a missing baby tooth until the permanent tooth erupts. The appliance is made of stainless steel wire and is secured in place by a band that fits around the tooth that is behind the open space. A wire or loop that is attached to the band is placed around the area of the missing tooth. The loop touches the tooth in front of the open space, which prevents shifting and enables the adult tooth to erupt in the right position.


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 a 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.
