What Is MSE?
You may also hear the term MSE, which stands for Maxillary Skeletal Expander. MSE is a specific type of MARPE (Miniscrew-Assisted Rapid Palatal Expansion) that uses a rigid expansion device supported by four miniscrews placed in the palate. While MARPE is the broader category for miniscrew-assisted expansion, MSE refers to a specific appliance design that is often used to achieve more pronounced skeletal widening of the upper jaw, particularly in the posterior region.
How the Process Works
Once the MARPE appliance is placed, it is gradually activated over the course of treatment, gently separating the mid-palatal suture to widen the upper jaw. The timeline varies based on the amount of expansion needed and each patient’s individual anatomy, but most active expansion phases are completed within a matter of weeks, followed by a retention period that allows the new bone to solidify. Research published on the National Institutes of Health’s PubMed Central confirms that MARPE has been shown to produce measurable skeletal gains in adolescent and adult patients, with outcomes that differ significantly from tooth-borne expansion alone. Our approach is a slower turn rate, minimizing any major diastema formation in between the front teeth.
The MARPE appliance is fixed in place during treatment, so there’s nothing to remove or remember to wear. Patients adjust quickly, and most find the process far more manageable than they anticipated.
Who Is a Candidate for MARPE?
MARPE is most commonly recommended for patients who present with a transverse maxillary deficiency, meaning the upper jaw is narrower than it should be relative to the lower jaw. This can show up as a crossbite, noticeable crowding, or complaints about breathing and sleep disruption. Because the miniscrews bypass the teeth and anchor directly in bone, MARPE extends the window of non-surgical palatal expansion beyond what was historically possible.
We offer MARPE for both teens and adults. For younger patients, the mid-palatal suture is still more flexible, which tends to allow for faster and more predictable results. For adults, MARPE remains a highly effective option, particularly when treatment is carefully planned around the patient’s bone density and suture maturation. Our team conducts a thorough evaluation before recommending any course of treatment, including digital imaging when appropriate, to ensure MARPE is the right fit for your anatomy and goals.
The Connection Between Palate Width and Airway Health
One of the most compelling reasons to consider MARPE isn’t just about alignment. A narrow palate frequently corresponds with a narrowed nasal airway, which can contribute to mouth breathing, disrupted sleep, and poor oxygen intake over time. Expanding the upper jaw creates more space not only in the mouth but in the nasal cavity as well, which is why MARPE is often part of a broader airway-focused treatment plan.
Patients who undergo MARPE as part of airway orthodontics sometimes report improvements in breathing and sleep quality alongside the structural changes in their smile. While results vary and we never promise specific outcomes, the relationship between jaw structure and airway function is well established in the research literature.
Why Patients in Lincoln Park Choose MARPE Over Surgery
Before MARPE existed, many adults with narrow palates were told that surgical palatal expansion was their only option. Surgically-assisted rapid palatal expansion, or SARPE, remains a valid treatment in some cases, but it comes with the inherent risks, recovery time, and cost of an operating room procedure. MARPE offers a non-surgical path to the same skeletal outcome for patients who qualify.
Not everyone is a candidate for MARPE without surgical assistance, which is part of why a thorough evaluation is so important. Our team takes pride in being honest with patients about what treatment will and won’t achieve, and we take time to explain the reasoning behind every recommendation. If you’ve been wondering whether you might be a candidate, a conversation with us is the best place to start. Learn more about the signs that airway treatment may be worth exploring on our blog.

Frequently Asked Questions
How long do cosmetic dentistry results last?
The longevity of cosmetic dentistry varies by treatment: teeth whitening lasts 1 to 3 years with good care, dental bonding typically lasts 3 to 7 years, porcelain veneers can last 10 to 20 years with proper maintenance, and dental crowns often last 15 to 25 years or longer. Factors affecting longevity include your oral hygiene habits, diet and lifestyle choices, teeth grinding or clenching, and regular dental maintenance.
Is cosmetic dentistry covered by insurance?
Most cosmetic dentistry is not covered by dental insurance since it’s considered elective. However, some treatments may have partial coverage if they also serve a functional purpose, such as crowns for damaged teeth. We’ll help you understand your insurance benefits and submit claims when applicable. We also offer flexible payment plans, CareCredit financing, and our in-house membership plan to make cosmetic treatments more affordable.
What's involved in a cosmetic dentistry consultation?
Your cosmetic consultation includes a comprehensive examination of your teeth, gums, and bite, discussion of your aesthetic goals and concerns, digital photography to document your current smile, review of treatment options and alternatives, computer imaging or mock-ups when appropriate, detailed cost estimates and treatment timeline, and discussion of financing and payment options. The consultation typically takes 45 to 60 minutes and helps us design a personalized treatment plan.
Can cosmetic dentistry fix gaps between teeth?
Yes, we offer several options to close gaps between teeth depending on the size and location. Small gaps can often be closed with dental bonding in a single appointment, while larger gaps may benefit from porcelain veneers for a more permanent solution. Multiple gaps or spacing issues throughout the mouth may be best addressed with orthodontic treatment like Invisalign. During your consultation, we’ll evaluate your specific situation and recommend the most appropriate solution.
How do I maintain my cosmetic dentistry results?
Maintain your cosmetic dentistry results by practicing excellent oral hygiene with regular brushing and flossing, scheduling professional cleanings and check-ups every six months, avoiding staining substances like coffee, tea, and tobacco when possible, wearing a night guard if you grind your teeth, and using a soft toothbrush and non-abrasive toothpaste. Following these guidelines will help preserve your investment in your beautiful smile.
