Nance Appliance

The Nance Appliance is used to prevent upper molars from rotating or moving forward while we close upper arch space.

The 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.

Distal Jet Appliance

The Distal Jet Appliance is a non-removable appliance that is used to move upper back teeth backwards.

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 stop attached to the tracking wire. The Distal Jet can be converted to a Nance Appliance by tightening the locking screws against the track wire.

Hilger's Appliance

The Hilger's Appliance is also used to move upper back teeth backwards upper molars.

This appliance consists of a plastic “button” that touches the roof of the mouth and spring that  moves the molars back using the roof of the mouth as an anchor.  Patients usually wear this appliance for approximately 6 months.

Lower Lingual Arch

A Lower 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 Lower Lingual Arch is removed following the eruption of all the permanent teeth.

Rapid Maxillary Expander

Attached to the upper molars through bonding or by cemented bands, the Rapid Maxillary 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.

Upper Removable Appliances

A URA, or Upper Removable Appliance, is an acrylic appliance that sits on the roof of the mouth with wires to hold it in place and encourage the teeth to move or stay in their correct position. URA's can be helpful with correcting cross bites on front teeth, to maintain space between teeth or to stabilize teeth after orthodontic treatment has been completed.

Trans-palatal Arch

The 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 and 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 your Trans-Palatal Arch.
