At San Marcos Orthodontics, we offer advanced orthodontic solutions for teens and adults who need more than traditional braces or clear aligners alone. One of the most effective options for patients with a narrow upper jaw is MARPE, a modern expansion treatment designed to widen the upper arch and improve long-term bite stability.
This treatment can help create the space needed for proper alignment while supporting healthier jaw balance and improved function.
What Is MARPE?
MARPE stands for Miniscrew-Assisted Rapid Palatal Expansion. It is a specialized orthodontic expander supported by small temporary anchor screws (miniscrews) that help guide expansion through the upper jaw more efficiently than older expansion methods.
MARPE is commonly recommended for teens and adults who have a narrow palate and need expansion before braces or aligners can achieve the best result.
Who Can Benefit From This Treatment?
This option is often recommended for patients who have:
- A narrow upper jaw
- Crossbite (upper teeth sitting inside the lower teeth)
- Crowding caused by limited arch space
- Bite imbalance related to jaw width
- A need for expansion before braces or aligners can work properly
A consultation at San Marcos Orthodontics helps determine whether this is the right solution based on your bite, jaw structure, and orthodontic goals.
How Does Jaw Expansion Work?
This appliance gradually widens the upper jaw over time using controlled activation. Because it is supported by miniscrews, it can create more predictable expansion in patients who may not be candidates for traditional expanders.
Expansion helps:
- Improve the width and shape of the upper arch
- Create space for crowded teeth
- Support better upper and lower bite alignment
- Reduce the need for tooth extractions in certain cases
What Are the Benefits?
Patients often choose this approach because it may:
- Expand the upper jaw more effectively in teens and adults
- Improve bite alignment and arch balance
- Help relieve crowding by creating additional space
- Support more stable orthodontic results long-term
- Works well as a preparatory step before braces or clear aligners
What Happens After Expansion?
After the expansion phase, most patients continue into the next step of treatment, which may include:
- Braces
- Clear aligners
- Other orthodontic appliances based on your treatment plan
Your orthodontist will guide the full timeline so your results remain stable and predictable.
What Can I Expect During Treatment?
Most patients experience:
- Mild pressure during activations
- A gradual widening sensation as expansion progresses
- A short adjustment period for speaking and eating
Our team at San Marcos Orthodontics will provide clear instructions, monitor progress, and make sure everything stays comfortable and on track.

Frequently Asked Questions
MARPE is a modern jaw expansion option that can play an important role in creating space and improving bite stability for teens and adults. Below are common questions we hear from patients considering treatment.
Is MARPE Only For Kids, Or Can Adults Get It Too?
MARPE is often recommended specifically for teens and adults who need upper jaw expansion but may not respond well to traditional expanders alone.
How Do I Know If I Have A Narrow Upper Jaw?
Common signs include crowding, a crossbite, or a bite that feels “off.” The best way to confirm is with an orthodontic evaluation that reviews jaw width and bite alignment.
Will MARPE Create Space Without Removing Teeth?
In many cases, yes. Expansion can help create additional arch space, which may reduce the need for extractions depending on your crowding and bite goals.
How Long Does The Expansion Phase Usually Take?
The expansion process is gradual and varies by patient. Your orthodontist will guide your activation schedule and monitor progress throughout treatment.
Is MARPE Uncomfortable?
Most patients report mild pressure during activations and an adjustment period for speaking and eating. Discomfort is usually temporary and manageable.
