The Invisalign Palatal Expander (IPE) System

The Invisalign Palatal Expander (IPE) is a breakthrough orthodontic device designed to gently and predictably widen the upper jaw (maxilla) in growing children. Unlike traditional metal expanders that require turning a screw every night, the Invisalign IPE is 3D-printed, removable, and completely metal-free, offering a modern, comfortable alternative for early orthodontic care.

Why Choose the Invisalign Palatal Expander?

• Metal-free and screw-free design: No bulky metal parts or screws to turn at home — just smooth, comfortable fit.
• Enhanced comfort: Minimal irritation, fewer emergency visits, and better speech comfort for young patients.
• Removable for hygiene: Makes brushing and flossing easy, reducing the risk of cavities or gum irritation during treatment.
• Digitally planned expansion: Each stage is precisely programmed for gradual widening (~0.25 mm per step) to ensure safe, controlled movement.
• Predictable results: Digital design ensures a perfect fit and reliable, consistent expansion outcomes.

How It Works

• Digital Prescription & Scan: Treatment begins with a quick, comfortable 3D intraoral scan (such as iTero) to capture the exact shape of your child’s teeth and palate.
• Staged Expansion: A series of custom 3D-printed expanders are made, each programmed to gently widen the upper arch by approximately 0.25 mm per stage.
• Stabilization Phase: Once the desired width is achieved, retentive holders keep the palate stable while new bone naturally forms in the mid-palatal suture.
• Transition to Aligners: After expansion is complete, your child can continue with Invisalign First or full orthodontic treatment for tooth alignment and bite correction.

Benefits for Families

• A comfortable, removable, and hygienic approach to upper-jaw expansion
• Ideal for growing patients between ages 6 and 12
• Designed and monitored digitally by an orthodontic specialist
• Provides predictable, precise, and safe expansion — without the metal or manual adjustments of traditional expanders
