Nance Appliance | Pendulum Appliance | Thumb/Finger Appliance | Tongue Thrusting Appliance

Nance Appliance

The Nance Appliance is used to prevent upper molars from rotating or moving forward after you’ve worn a headgear, a Wilson’s arch 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.

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.

Pendulum Appliance

The Pendulum Appliance is used to correct class II malocclusions by distalizing upper molars. It’s used to correct the patient’s bite on the side of their mouth.

The Pendulum Appliance consists of a plastic “button” that touches the roof of the mouth and resilient wire springs that act in a broad swinging arc to move the molars back. The appliance uses the roof of the mouth as an anchor to move the molars back into their correct positions. Patients usually wear this appliance for 3 to 5 months.

Thumb/Finger Appliance

Sucking is a natural reflex that relaxes and comforts babies and toddlers. Children usually cease thumb sucking when the permanent front teeth are ready to erupt. Typically, children stop between the ages of 2 and 4 years. Thumb sucking that persists beyond the eruption of primary teeth can cause improper growth of the mouth and misalignment of the teeth. If you notice prolonged and/or vigorous thumb sucking behavior in your child, talk to your dentist.

One solution to thumb sucking is an appliance called a "fixed palatal crib." This appliance is put on the child's upper teeth by an orthodontist. It’s placed behind on the upper teeth on the roof of the mouth. The crib consists of semicircular stainless steel wires that are fastened to molars using steel bands. The stainless steel wires fit behind the child's upper front teeth, and they are barely visible. The crib usually stops the habit of thumb sucking within the first day of use.

Tongue Thrusting Appliance

Tongue thrusting occurs when the patient presses his or her tongue against the front teeth, usually when swallowing, speaking or resting the tongue. If thrusting is constant, this can cause problems with teeth alignment and must be fixed.

We prefer to correct tongue thrusting by giving patients a tongue thrusting appliance. This appliance, similar to a mouth guard, is usually worn at night. Other times, a more permanent appliance is prescribed and can be only be adjusted by our office.
