Types of Appliances


This appliance can be used to help underbite correction in young children, generally between the ages of seven and ten.

X-bow Class 2 corrector

This appliance is used to help address:

  • deficient lower jaws
  • large overjets
  • large overbites
  • protruding upper jaws
  • blocked-out canines
  • narrow upper jaws

We are happy to be able to offer our patients this appliance, since it has been shown to be the most efficient and effective, even when compared to other appliances such as twin block, Herbst, and MARA. The components we use are from 3M Unitek.

The appliance is generally used for six to eight months, depending on the amount of correction required. It works by moving the upper teeth/jaws back and the lower teeth/jaws forward. The appliance itself is not painful, but can take up to a week to get used to. It will get better!

Following the appliance, full braces or Invisalign® is used to align the teeth, ranging between a year to a year and a half, depending on the malalignment of the teeth.

Generally, we will avoid the use of this appliance with good elastic wear!

Elastics (Rubber Bands)

Wearing elastics (or rubber bands) improves the fit of your upper and lower teeth. Wear rubber bands as instructed, and remember the rubber bands work far more efficiently if they’re worn as prescribed.


palatal expander

Palatal Expander

The palatal expander “expands” (or widens) your upper jaw by putting gentle pressure on your upper molars each time an adjustment is made. We will instruct you about when and how to adjust your expander. When you achieve the desired expansion, you will wear the appliance for several months to solidify the expansion and to prevent regression.




Retainers may be removable or fixed. They hold your teeth in their new, correct positions after your teeth have been straightened. Your orthodontist will instruct you on how to care for your retainer and about the duration of the wear. Wearing your retainer as directed is crucial to prevent regression of your treatment.



Separators or Spacers

Separators are little rubber doughnuts that may be placed between your teeth to push them apart so orthodontic bands may be placed during your next appointment. The separators will be removed before we place the bands. Separators do not mix well with sticky foods, toothpicks, or floss.
