Types of Appliances
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 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 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.
Headgear is used to treat patients whose teeth are in an overbite, with the upper jaw forward of the lower jaw, or an underbite with the lower jaw forward of the upper jaw. Headgear gently "pulls" on your teeth to restrict further forward growth of your upper teeth and jaw.
Invisalign Mandibular Advancement
Traditionally, overbites have been treated with Headgear or Herbst appliances, but now these same clear aligners can also be used to encourage the lower jaw to move forward in younger patients who are still growing.
Invisalign with Mandibular Advancement looks much like regular Invisalign aligners, with one key difference: there are wings located between the premolars and first molars on both the top and bottom set of aligners. These two sets of wings interlock and place the lower jaw in a more advanced position. With time, skeletal correction takes place, with the lower jaw eventually growing into its proper placement, eliminating the overbite.
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.
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.
Temporary anchorage devices, or TADs, are small titanium anchors used in certain orthodontic cases to help achieve quicker tooth movement with more efficiency and comfort. TADs may be used in addition to braces or as an alternative to headgear.
