What is a Palatal Expander?

A palatal expander, often referred to as a rapid palatal expander (RPE), is a custom-fitted orthodontic device designed to gradually widen your upper jaw. By applying gentle and consistent pressure, it creates space for proper tooth positioning and enhanced bite function.

Types and Mechanisms of Palatal Expanders

There are different kinds of palatal expanders, each designed to suit patient requirements.

Rapid Palatal Expander (RPE)

Ideal for younger patients, this classic device connects to the molars and employs a specific screw mechanism for accurate changes. It works best before the palatal suture closes, making timely intervention vital.

Bone-Borne Expanders

Utilizing miniscrew technology, these expanders are especially beneficial for patients with specific dental issues, such as cleft palates. They’re particularly ideal for adults and older teens.

Miniscrew-Assisted RPE (MARPE)

Designed for older teens and adults, this modern method utilizes mini-implants to attain maximum skeletal adjustments with little dental movement.

Who Is a Candidate for MARPE in San Antonio?

MARPE is usually considered for older teenagers and adults, whose palatal suture has started to fuse and no longer responds predictably to a tooth-borne expander. Candidacy depends on palatal anatomy, the width of the upper jaw and the bite, all of which are assessed at a consultation before anything is planned.

How Is MARPE Different From a Rapid Palatal Expander?

A rapid palatal expander anchors to the molars and pushes the two halves of the upper jaw apart, which works while the palatal suture is still open. MARPE adds mini-implants that carry the force into the bone itself, so an older patient can get skeletal widening with less tipping of the teeth.

Who Performs Jaw Surgery, and What Does the Orthodontist Do?

Corrective jaw surgery is performed by an oral and maxillofacial surgeon after a referral from an orthodontist. When a bite needs more correction than expansion alone can provide, our San Antonio orthodontist aligns the teeth with braces ahead of the operation. The surgery itself is done by the surgeon, not in our office.

Where Can I Get a MARPE Expander in San Antonio?

The Process of Impression or Scan and Placement of Separators

Impression and Digital Scan

We’ve upgraded from old impression techniques to modern digital scanning technology, delivering better accuracy for your custom expander design.

Placement of Spacers or Separators

Before fitting your expander, if needed, we gently place spacers to create enough room between your teeth. Our careful method reduces discomfort. This may not be required for some types.

Advantages of 3D Printed Appliances 
and Digital Scans

We take pride in using advanced technology to design accurately fitting expanders, minimizing adjustment requirements.

Digital Workflow in Palatal Expander Fabrication

Our clinic uses advanced digital processes to make virtual models of your mouth, making sure each palatal expander is tailored to your individual dental structure.

Effectiveness and Outcomes

Addressing maxillary concerns has shown promising results, particularly in promoting skeletal adaptations during developmental phases.

What Palate Expanders Do

Palatal expanders are used to widen the upper jaw and correct the bite. Our page on mouth breathing covers the breathing side of this separately.

Impact on Speech and Comfort

Though there may be a short adjustment phase, our patients usually adapt swiftly to their palatal expanders. Our team offers full support during your treatment process.

Impact on Sleep Apnea and Snoring

Obstructive Sleep Apnea (OSA) is a condition that causes airway blockages while sleeping, often resulting in snoring and breathing interruptions. It is diagnosed by a physician, usually with a sleep study. We refer patients who may have it to local ear, nose and throat (ENT) doctors.

Clinical Evidence

Research on palatal expansion and sleep apnea is still developing, and expansion does not replace a physician’s diagnosis and care.

Early Orthodontic Intervention

Early orthodontic treatment in kids can be vital. Widening the palate during development makes room for crowded teeth.

Importance of Comprehensive Diagnosis

We refer patients for CBCT imaging when needed.
