Expanders and Motion Appliance Q & A

Iris Erdell, DDS, MS Orthodontist

What is an expander?

An expander is an orthodontic appliance that gently stretches the bone and cartilage in your palate to make more room for your teeth. An expander can be used on your top or bottom jaw, but it’s more often used for the top jaw. Expanders can be removable or fixed.

Who needs an expander?

You may need an expander if you have:

  • Overcrowding
  • Misalignment
  • Overbite
  • Crossbite

Dr. Erdell may recommend expanders to widen your jaw, improve the fit between your upper and lower teeth, or move your teeth to make space so that your braces have an easier time moving your teeth into a better position.

Although adults can use expanders, they work best when placed before the jaw bones become too solid.

What is a Carriere motion appliance?

A motion appliance is an orthodontic appliance that moves the upper and lower teeth to give you a correct bite. Dr. Erdell recommends placement of the motion appliance before braces so the important bite correction can be done first.

The motion appliance has the same effect as a traditional orthodontic headgear, but it is less invasive and bulky. It consists of two curved metal bars that attach to two upper teeth and a lower holding arch or clear retainer. Elastic bands are used to create the necessary force to move your teeth.

Who needs a motion appliance?

You may need a motion appliance if you have:

  • Overbite
  • Overjet
  • Misalignment
  • Overcrowding

However, although a motion appliance has many uses, it’s primarily recommended to move the back teeth to fix an overbite by moving your teeth to make room for the realignment of your bite without having to extract your teeth.

Using a motion appliance before braces may also help shorten the amount of time you have to wear braces.

Both children and adults benefit from the use of motion appliance.

If you’re unhappy with your smile, Dr. Erdell can help. Whether you have an overbite, overcrowding, or misalignment, Dr. Erdell offers many options to help fix your smile.
