What Is Midfacial Expansion?
Midfacial expansion at Dr. Koval Orthodontics is a gentle, science‑driven approach to improving facial balance, airway health, and long‑term orthodontic stability. Using the MARPEFACE protocol, we guide the midface to grow forward and outward in a way that feels natural and supportive for both kids and adults. This treatment focuses on enhancing facial harmony, improving posture, and creating the skeletal room needed for comfortable breathing and optimal dental alignment. Our team is committed to making each step clear, comfortable, and personalized to your goals.
The Benefits of Midfacial Expansion
Improved Facial Balance
Midfacial expansion enhances cheek support, forward maxillary projection, and overall facial harmony. Patients often notice a more balanced and confident appearance as the midface develops into a fuller, more supported shape.
Better Airway and Breathing
By expanding the palate and improving the nasal cavity space, breathing becomes easier and more efficient. Many patients experience improvements in sleep quality, daytime focus, and athletic performance.
Enhanced Posture and Alignment
The MARPEFACE protocol helps correct postural head bend and supports healthier head‑neck alignment. This can reduce strain, encourage better breathing mechanics, and improve long‑term musculoskeletal balance
The Midfacial Expansion Treatment Process
MARPE Installation
Treatment begins with the placement of the MARPE appliance, a comfortable device supported by micro‑implants for stable skeletal expansion. Our team ensures the installation process is gentle, clear, and tailored to your needs. After placement, we provide detailed instructions on activation and what to expect during the first few days.
Active Expansion (6–10 Weeks)
During this phase, the mid‑palatal suture gently separates, allowing the midface to rotate upward, outward, and forward. We monitor progress closely while the MARPEFACE protocol supports improvements in head posture, facial symmetry, and airway development. Patients often begin noticing visual and functional changes within the first few weeks.
Stabilization Phase (6–8 Months)
Once expansion is complete, the appliance remains in place to allow new bone to develop and solidify within the suture. This stability phase is essential for long‑term success, ensuring the midface maintains its new shape. During this time, facial changes continue to refine as muscles adapt and posture improves.
FAQs
How long does the entire MARPEFACE process take?
The full process typically lasts 7–10 months. This includes 6–10 weeks of active expansion followed by a 6–8‑month stabilization period to allow new bone to form and support the expanded midface.
Is midfacial expansion painful?
Most patients report mild pressure or soreness during activation, especially in the first few days. Discomfort is usually temporary, and our team provides strategies to keep you comfortable throughout treatment.
What age is best for midfacial expansion?
While younger patients often respond quickly, MARPEFACE is effective for teens and adults as well. Because MARPE uses micro‑implants for support, it allows skeletal expansion even after the mid‑palatal suture has matured.
