A chin cup is used to close an openbite. It directs force on the lower jaw through the attachment of a cup that fits over the chin to a headcap.
Elastics (Rubber Bands)
Wearing elastics (or rubber bands) improves the fit of your upper and lower teeth. Wear rubber bands as instructed, and remember they work far more efficiently if they’re worn as prescribed.
An orthodontic face mask (reverse headgear) is used to correct an underbite. The mask is designed to fix the discrepancy between your upper and lower jaws by moving the upper jaw forward.
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.
A lip bumper is an arch wire attached to a molded piece of plastic. The lip bumper holds back the molars on your lower jaw to provide more space for your teeth.
The palatal expander “expands” (or widens) your upper jaw by putting gentle pressure on your upper molars each time an adjustment is made. Dr. Feeney 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 they have been straightened. We 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 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.
