Types of Appliances

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.



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.


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. Our doctors 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. Our doctors 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.


T Rex

T-Rex Appliance

The T-Rex appliance is a fixed appliance made to the upper jaw. It is used to move the upper molars backwards, similar to the effects of headgear. It allows our doctors to correct the upper molar position and gain arch length, helping avoid permanent tooth extractions. It is not removable by the patient, and is typically worn for 4-6 months.



Habit Appliance

Thumb sucking that persists beyond the eruption of primary teeth can cause improper growth of the mouth and misalignment of the teeth. One solution to thumb sucking is an appliance called a Palatal Crib. Our doctors put the appliance on the child's upper teeth. It's placed behind on the upper teeth on the roof of the mouth. The appliance consists of two molar bands with stainless steel wires that are fastened to the bands creating the crib to control the habit.




The Carriere is an orthodontic device developed to correct a misaligned bite without removing permanent teeth. It has a dental effect similar to a headgear but without relying on patient cooperation.




The Forsus Fatigue Resisitant Device, patients are able to gt an ideal bite without sacrificing comfort and convenience. The Forsus promotes growth in adolescents, helping to eliminate excessive overbites, improve the fit of the teeth and possibly prevent the need for jaw surgery.


Full Splint

Full Splint

A full coverage splint appliance is a clear acrylic appliance that conforms exactly to the contours of the teeth to aid in establishing even contact between the upper and lower teeth. This appliance is used mainly for people with TMJ and that have grinding issues to help reduce trauma to the teeth and joints.
