Non-surgical expansion in adults? Yes — and it can be life changing!
In children, the two halves of the upper jaw have not fully fused yet, which makes expansion relatively straightforward. But in adults, that midpalatal suture is fused, meaning traditional expanders alone are often no longer enough to predictably widen the upper jaw.
That’s where MARPE (Miniscrew-Assisted Rapid Palatal Expansion) comes in. By using temporary anchorage screws for support, we can achieve true skeletal expansion in many adults without surgery — helping create a wider, healthier foundation for both the bite and the airway.
Alex started with a crossbite and narrow smile and finished with a beautiful, broad smile and improved arch development. Drs. Parnes and Rubin used a combination of a MARPE and Invisalign to achieve this beautiful result.
And the benefits of MARPE go far beyond aesthetics:
• Improved nasal breathing
• Increased airway space
• Better sleep quality
• Improved tongue posture
• Better long-term function and stability
Orthodontics is about so much more than straight teeth. Creating healthy jaw development can have a huge impact on how our patients breathe, sleep, and feel every day 💫
What a Transformation! 🤩🙌🏻🦷
