Rapid Palatal Expansion Appliance (RPE)

RAPID PALATAL EXPANSION APPLIANCE (RPE)

The palate widening appliance is a specially made device used to expand the upper arch or roof of the mouth. There are several reasons to widen the arch.
1. First, by widening the upper arch, the upper teeth may line up better with the lower teeth, giving the patient a better bite.
2. Second, where a high palate and a narrow arch restrict the breathing passages located above, widening the palate widens the air passages. The patient can breath more easily through his nose.
3. Third, widening the palate can make more room for crowded teeth to align better.

¨ The expanding action of the appliance gently separates the elastic membrane in the center of the palate. Once the palate has been expanded fully, new bone tissue fills that space.

¨ The upper arch is usually expanded enough in 6 to 8 weeks, however, the appliance is allowed to remain in the mouth for a longer period while new bone is generating in the expanded arch.

¨ You will notice that widening the palate also temporarily causes a space between the two front teeth. Do not be alarmed. The space closes again naturally.

¨ Also, the same pressure on the roof of the mouth may cause a tingling sensation at the base of the nose and a feeling of pressure in the teeth. Usually, any over-the-counter pain reliever will effectively relieve the discomfort. If it does not, call the office so we can check your appliance.

TURNING INSTRUCTIONS

Turn the Upper appliance ONE TURN EVERY DAY, unless otherwise directed.

If a Lower Schwartz appliance is used: REMOVE from the mouth to turn and turn ONE TURN EVERY FIVE DAYS.

1. Be sure to place your finger in the loop that is attached to the RPE key. This is an important precaution against accidentally swallowing the key.

2. Carefully insert the key into the hole or slot in the middle of the appliance.

3. Gently and steadily push the key from the front toward the back of the mouth. Do not back up. Remove the key toward the throat. You automatically bring a new keyhole position forward by pushing the key as far back as possible. It will be ready for the next activation.

PARENT'S RESPONSIBILITY:

Activate the appliance, closely follow the schedule and instructions given by Dr. Stich and be consistent! It is important not to rush or delay the activation of the appliance.

Be sure the appliance is correctly cleaned each time your child brushes. This, and the use of an oral irrigation device, if available, and mouthwash will keep the appliance free of food and prevent irritation.
