MARPE stands for miniscrew-assisted rapid palatal expansion. It is an orthodontic treatment used to widen a narrow upper jaw in older teens and adults who may not respond predictably to a traditional palate expander alone.
MARPE may be recommended for patients with crowding, crossbite, limited tongue space, or airway-related concerns connected to a narrow palate. The appliance uses small temporary anchorage devices to help guide expansion more directly through the upper jaw.
At Carvalho & Roth Orthodontics, your doctor will evaluate your jaw structure, bite, airway concerns, and long-term goals before recommending MARPE or another treatment option.
MARPE uses a custom palatal expander supported by small temporary anchorage devices. These help direct expansion forces toward the upper jaw instead of relying only on the teeth.
Your orthodontist will place the appliance, explain how activation works, and monitor your progress through follow-up visits. After expansion, the appliance typically stays in place for stabilization before braces, Invisalign, or another orthodontic treatment is used to refine alignment.
For the right patient, MARPE can create more room in the upper jaw, support better bite alignment, and help address concerns linked to a narrow palate.
Creates More Space for Crowded Teeth: MARPE can widen the upper jaw to make room for crowded or blocked-out teeth, helping future orthodontic movement become more predictable.
Helps Correct Crossbite: A narrow upper jaw can cause the teeth to bite unevenly. Palatal expansion can help improve how the upper and lower teeth fit together.
Supports Airway-Focused Treatment: In some patients, expanding the upper jaw may support better oral and nasal space as part of a broader airway-aware orthodontic plan.
Offers a Non-Surgical Option for Select Patients: MARPE may help some older teens and adults avoid more invasive expansion approaches, depending on their anatomy and treatment needs.
MARPE requires precise diagnosis and careful planning. Carvalho & Roth Orthodontics combines advanced training, modern orthodontic techniques, and boutique doctor-led care for patients across Massachusetts.
Harvard-Trained Orthodontists: Dr. Carvalho, Dr. Roth, and Dr. Evers bring advanced orthodontic training to complex cases involving jaw development, bite correction, and expansion planning.
Airway-Aware Orthodontic Approach: We consider how the palate, jaws, bite, tongue space, and airway may work together when planning treatment.
Four Massachusetts Offices: Patients can visit us in Marlborough, Northborough, Newton Centre, or Worcester for consultations and follow-up care.
Boutique, Doctor-Led Care: Your treatment is planned around your diagnosis, comfort, goals, and long-term stability, not a one-size-fits-all process.
Complete Orthodontic Support: If MARPE is part of your plan, we can also coordinate braces, Invisalign, retainers, or other treatment needed to complete your smile.
Your orthodontist evaluates your bite, jaw width, palate, airway-related concerns, and smile goals. This helps determine whether MARPE is the right option or if another orthodontic treatment would be more appropriate.
We take the records needed to plan your treatment carefully. Your doctor will explain how MARPE fits into your overall orthodontic plan, including whether braces or Invisalign may be needed afterward.
If MARPE is recommended, your appliance is placed and supported with small temporary anchorage devices. Our team will explain how it works, how to clean around it, and what to expect during treatment.
You will follow your orthodontist’s instructions for activation while we monitor your progress. This phase gradually widens the upper jaw in a controlled way.
After expansion, the appliance usually remains in place for stabilization. Many patients then continue with braces, Invisalign, or retainers to complete alignment and protect the final result.
The cost of MARPE orthodontic treatment depends on your diagnosis, appliance design, treatment complexity, and whether expansion is combined with braces or Invisalign.
At your consultation, Carvalho & Roth Orthodontics will review your treatment plan, explain your fee clearly, and help you understand available insurance and payment options.

MARPE stands for miniscrew-assisted rapid palatal expansion. It is an orthodontic treatment used to widen the upper jaw with support from small temporary anchorage devices.
MARPE may be recommended for older teens or adults with a narrow upper jaw, crowding, crossbite, or airway-related concerns. Your orthodontist will confirm whether it is appropriate after reviewing your bite, jaw structure, and treatment goals.
MARPE is often considered a non-surgical palatal expansion option for select patients. Some complex adult cases may still require a different approach, which your orthodontist will explain during your evaluation.
MARPE may support airway-focused orthodontic goals in some patients by widening the upper jaw and creating more oral and nasal space. If you have breathing, snoring, or sleep-related concerns, your orthodontist may recommend working with a physician, ENT, or sleep specialist.
The active expansion phase may take several weeks, but the full timeline depends on your diagnosis, stabilization period, and whether braces or Invisalign are needed afterward.
Patients may feel pressure, tightness, or temporary soreness as the appliance begins working. Our team will explain how to manage discomfort and when to contact us if something feels unusual.
