What Is a Nance Appliance and When Should You Use it?

Dental appliances prevent teeth from moving or to shift teeth into a the proper place. While there are several types of appliances, a Nance appliance has a very specific function and can be used to expand or rotate the upper molars, or to hold molars in place. The most common use is as a space maintainer to prevent upper molars from drifting forward.

How does a Nance Appliance work?

The Nance appliance fits comfortably along the roof of the mouth with bands that are placed on the upper arch of the two back molars. A wire  connects the bands and a small  piece of acrylic is located at the center of the wire.

Are there lifestyle limitations with the Nance appliance?

Patients with the appliance should make sure to pay special attention to the roof of their mouth while brushing to prevent gum irritation. They should practice good oral hygiene and avoid drinking carbonated beverages, or avoid eating hard or sticky food. Eating or drinking these types of food can damage the appliance.

Only a Portland orthodontist can determine if the Nance appliance is appropriate for your teeth. Regular visits and consultations with your dentist and orthodontist can determine your proper orthodontic treatment.
