MARPE - Advanced Expansion for Teens and Adults
At New Smile Orthodontics, Dr. Hu offers MARPE (Miniscrew‑Assisted Rapid Palatal Expansion) as a modern, evidence‑based way to widen the upper jaw for older teens and adults who need more than traditional expanders.
MARPE is designed for patients whose jaws are no longer growing the way they did in childhood, providing a powerful yet conservative alternative to surgical jaw expansion.
What Is MARPE?
MARPE stands for Miniscrew‑Assisted Rapid Palatal Expansion, a specialized orthodontic appliance that uses tiny anchors (miniscrews) and a palatal expander to gently widen the upper jaw.
MARPE engages the bones of the palate directly and can provide a non-surgical method of widening the jaw for older children, teens and adults. This treatment is often used to:
-Widen a narrow upper jaw so upper and lower teeth fit together more naturally.
-Open up the airway and nasal passages in some patients, supporting easier breathing.
-Create more space for crowded teeth so braces or clear aligners can work more effectively.
Typical age ranges:
- Older Children & Teens – patients who are past the ideal age for standard expanders but within the range where MARPE can be effective.
- Young Adults – patients who are in their late teens and twenties whose palate is mature but may still respond well without surgery.
- Select Adults Beyond 30 – Dr. Hu will evaluate the patient’s age, growth stage, and imaging to decide whether MARPE is beneficial.
How MARPE Helps and Why It Matters
A narrow upper jaw isn’t just about how your smile looks—it can affect your bite, breathing, and long‑term oral health. Key benefits of MARPE include improved bite and jaw balance; by widening the upper jaw, MARPE can resolve crossbites and help the upper and lower teeth meet more evenly, reducing uneven wear and strain. MARPE also offers better support for orthodontic treatment, since creating skeletal space first makes it easier to align crowded teeth with braces or clear aligners and can lead to more stable, long‑term results. Another important benefit is potential airway and comfort improvements—in some patients, expansion can increase nasal volume and reduce mouth breathing, which may support easier breathing and an overall better quality of life. Research shows that MARPE has high success rates in carefully selected late adolescent and adult patients and reduces the need for surgery.

Dr. Hu offers MARPE because it gives the right patients a non‑surgical option to correct significant jaw width issues and set the stage for a healthier, more functional smile.
