Types of Appliances

palatal expander

Palatal Expander (RDE)

The palatal expander "expands" (or widens) your upper jaw by putting gentle pressure on your upper molars each time an adjustment is made. Your orthodontist 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.


herbst appliance

Herbst® Appliance

The Herbst® 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.


The AdvanSync appliance treats Class II cases by simultaneously correcting malocclusions (bite) while advancing the mandible (lower jaw). Its use reduces the need for two-phase treatment, provides maximum range of motion for eating and speaking, and can complete Class II treatment in six to nine months.

elastics (rubber bands)

Elastics (Rubber Bands)

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




The Forsus Fatigue Resistant Device is an alternative to headgear which promotes growth in adolescents, helping to eliminate excessive overbites, improve the fit of teeth, and possibly prevent the need for jaw surgery.




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 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.


Twin Block Appliance

The twin block appliance is unique from other functional appliances, as it involves two separate appliances (one for the upper arch and one for the lower arch) working together to create an advanced lower jaw position. This patient-friendly appliance is worn full time, including while eating, though it is removable for easy hygiene. It is also more comfortable than other jaw-correcting appliances, as it is made out of smooth acrylic and utilizes fewer wires.

The result of using a twin block appliance is a broad, beautiful smile, proper jaw function, improved profile, and a stable and healthy temporomandibular joint.
