Shift Your Bite Into High Gear

WHEN UPPER AND LOWER DENTAL MIDLINES do not line up and the lower jaw moves to the side on closing, these are signs of a bite functional shift.

When The Upper Arch Is Too Small For The Lower...

When the upper arch is too narrow or too small for the lower jaw, the lower jaw is forced to move to the side when closing. The unwanted movement, called a functional shift, temporarily relieves discomfort by creating a maximum tooth biting surface for chewing. The unnecessary jaw movement can be eliminated by upper arch expansion and comprehensive orthodontic treatment.

The Imbalance Can Be Fixed

The upper jaw may also be too small for the face and the lower jaw. This is called maxillary deficiency. The backward position of the upper jaw can be corrected with Class III rubber bands, reverse pull headgear, or an upper jaw surgical advancement procedure.

This case was treated by board certified orthodontist Dr. Ann Marie Gorczyca of Gorczyca Orthodontics in Antioch, California.
