Mini-screw Assisted Rapid Palatal Expander (MARPE)

The MARPE expander is used to widen your arch in order to correct a crossbite or create room for your teeth. To use the expander the key/wrench must be used to turn the screw towards the back of the mouth (throat). This completes one turn.

For the MARPE we require 1 turn per day until suture splits (A space will appear between your upper front teeth) then 1 turn every other day

• If you turn the MARPE 1x per day for 2 weeks and don’t see a space between your front teeth, please come into our office for evaluation.

It is best to turn the expander at night before you go to sleep. While expanding we need to see a space between your front teeth. This is how we know the expander is opening the suture, If a space does not form after 1-2 weeks it is possible you are not turning the key correctly so it is best to contact your orthodontist.

It is very common to experience some pressure or tingling in the roof of your mouth or on your nose for a short time while using a MARPE.

It is very important to brush your expander and its arms thoroughly every time to brush your teeth. If you see that the gums around your expander are getting red and inflamed please contact your orthodontist.

Most Orthodontists keep the MARPE in for 6 months to 1 year after the final turn to allow the sutures to heal and prevent any relapse.

What is MARPE?

The MARPE appliance is a modern orthodontic device used to widen the upper jaw (maxilla) in patients where conventional methods may not be sufficient. Unlike traditional rapid palatal expanders (RPE), MARPE utilizes miniscrews that anchor to the palate, providing additional stability and direct skeletal expansion. This method is especially beneficial for older teens and adults whose jaw growth has slowed or stopped.

How Does MARPE Work?

MARPE applies gentle, controlled pressure to separate the two halves of the upper jaw, expanding the mid-palatal suture. The miniscrews ensure the force targets the bones rather than just the teeth, promoting effective skeletal changes.

The appliance is custom-made and secured to your upper molars, with miniscrews inserted into the palate by your orthodontist or oral surgeon. Over time, gradual expansion creates more space, improving both function and appearance.

Benefits of MARPE

1. Non-Surgical Option for Adults
   MARPE provides an effective alternative to surgery for many patients, making jaw expansion possible even after growth has ceased.

2. Improved Airway Function
   By expanding the upper jaw, MARPE can increase the airway space, helping patients who experience breathing issues such as sleep apnea.

3. Enhanced Smile and Bite Alignment
   MARPE creates room for crowded teeth and improves bite relationships, ensuring a healthier, more balanced smile.

4. Minimally Invasive Procedure
   The miniscrews used in MARPE are small and minimally invasive, with a quick recovery time for most patients.

5. Stable Long-Term Results
   MARPE’s direct impact on the skeletal structure ensures more predictable and stable outcomes.

Who Can Benefit from MARPE?

MARPE is ideal for patients who:

• Have a narrow upper jaw that causes bite issues (crossbite, crowding, or asymmetry).

• Are teens or adults for whom traditional expanders are less effective.

• Experience breathing or airway problems that may improve with jaw expansion.

• Prefer a minimally invasive approach to upper jaw correction.

What to Expect During Treatment

1. Consultation and Examination
   During your first visit, we’ll evaluate your jaw structure, teeth alignment, and overall oral health. Digital imaging and X-rays may be used to determine if MARPE is right for you.

2. Appliance Placement
   The MARPE appliance is custom-fitted and secured in a single visit. Miniscrew placement is quick and straightforward, with local anesthesia to ensure your comfort.

3. Activation Phase
   You’ll activate the expander daily using a provided key. This gradual process allows for controlled expansion over several weeks.

4. Retention Phase
   After achieving the desired expansion, the MARPE remains in place for a few months to stabilize the results.
