Expanders are used to correct crossbites and to create additional space for crowding of teeth. They are very effective in younger children and may eliminate the need to remove any permanent teeth.
By fitting a key in the center of the appliance and turning the key in the direction of the arrow twice per week, the expander will widen the upper jaw. You may notice a gap develop between the front teeth.

The crozat expander is made of wires and is attached to the molar teeth. There are two arms which come forward to widen the lower teeth. Each time you come in, the expander is removed and adjusted to expand the teeth.
Headgear is used to treat patients whose teeth are in an "overbite," (with the uppers forward of the lowers) or an "underbite" (with the lowers forward of the uppers). Headgear is worn at home and when sleeping and acts to modify the growth of the jaws to achieve an even and harmonious profile and bite.
The MARA appliance reduces overbite by encouraging the lower jaw forward and the upper molars backward. This fixed appliance is used mostly for younger, growing children and is worn for about 12-15 months.
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 are little rubber doughnuts that may be placed between your teeth to push them apart so that 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.
