Rapid Palatal Expander

RPE.jpgAttached to the upper molars through bonding or by cemented bands, the Rapid Palatal Expander is an orthodontic device used to create a wider space in the upper jaw. It is typically used when the upper jaw is too narrow for the lower jaw or when the upper teeth are crowded or blocked out of the dental arch.

When patients are still growing, their connective tissue between the left and right halves of their upper jaw is very responsive to expansion. By simply activating the expander through turning a screw in the center of the palatal expander, with a special key we provide, gradual outward pressure is placed on the left and right halves of the upper jaw. This pressure causes an increased amount of bone to grow between the right and left halves of the jaw, ultimately resulting in an increased width.

TADs (Temporary Anchorage Devices)

TAD.jpgOne of the many important advances in orthodontics has been the development of temporary anchorage devices, or TADs. Made of a bio-compatible titanium alloy, TADs are miniscrew anchors which are inserted into specific places in the mouth to be used as a fixed point from which teeth can move. Before TADs, orthodontists who wanted to move some teeth while keeping others still, or to achieve orthodontic movement in a mouth with missing teeth, had to rely on headgear for their fixed point. But TADs now provide an option for that fixed point that is smaller, more discrete, more efficient and requires significantly less work for the patient.

Temporary anchorage devices may not be recommended for everyone, and in fact, anchorage devices at all may not be needed in all cases. Contact us if you'd like to know more about TADs and how they can potentially prevent you from needing orthodontic headgear.

Forsus Appliance

You may notice some discomfort initially, so we recommend a soft food diet for the first few days after the appliance is placed. Regular anti-inflammatory medication may help with any pain, if needed. It is important to keep the appliance clean; you may do this by carefully brushing the coil and other metal pieces of the appliance. Also, we recommend that patients not open their mouths very wide, as the appliance may come apart.

If your Forsus appliance breaks, please contact our office immediately to schedule a repair appointment.

Nance Appliance

The Nance is made of two bands that are cemented onto the first molars and a wire spans the roof of the mouth from one side to the other. An acrylic pad covers the wire that touches the roof of your mouth directly behind your front teeth.

Brushing and flossing daily is very important. Be sure to clean around the bands that are connected to the molars and the wire on the tongue side. This will prevent the formation of cavities or infection of the gums.

The time that the nance appliance will be used varies. Dr. Donaghey will monitor the eruption of new teeth and advise the optimal time of removal.

Lower Lingual Arch

The lower lingual arch is made of two bands that are cemented onto the first molars and a wire spans behind the lower front teeth connecting to the cemented bands.

Brushing and flossing daily is very important. Be sure to clean around the bands that are connected to the molars and the wire on the tongue side. This will prevent the formation of cavities or infection of the gums.

The time that the lingual arch will be needed varies. Dr. Donaghey will monitor the eruption of new teeth and advise the optimal time of removal of the appliance.

Herbst

herbst.jpgOne of the most common problems orthodontists treat is an overbite, where the upper teeth protrude too far beyond the lower teeth. Ordinarily, when we see a patient with the upper teeth protruding, we tend to think that the upper jaw and teeth are too far forward; but, more often than not, this condition is due to a small lower jaw that is further back than it should be. With these patients, we would like to encourage the lower jaw to catch up while it is growing, and braces like the Herbst appliance help this happen.

As with all kinds of braces, patients with Herbst appliances need to be careful about what they eat. Sticky foods such as caramels, bubble gum and candy suckers will pull the brace away from the teeth. Hard foods like crisp vegetables and hard candies will bend and loosen the Herbst appliance, too. So stay away from these foods during your orthodontic treatment.

Your Herbst appliance will be checked and adjusted at your appointments. If between appointments you develop some sore areas on the inside of your cheeks, please do not try to adjust the appliance yourself. Call for an appointment so that the necessary adjustments can be made.
