Leaf Expanders

Leaf expanders use flexible nickel titanium springs to deliver gentle, continuous force for controlled arch expansion without the need for manual activation.

Continuous Force Delivery: Applies a constant low-level force using nickel titanium leaf springs, promoting steady and predictable expansion over time.
No Manual Activation Needed: Options like the Self-Activated Leaf Expander begin working immediately after placement, minimizing the need for patient compliance.
Compact and Comfortable Design: Low-profile structure ensures better fit and comfort, especially in younger patients or cases requiring minimal appliance bulk.

FAQ

We’re here to answer all of your questions

What’s the difference between the Spring-Activated and Self-Activated Leaf Expanders?

The Spring-Activated model requires orthodontist activation using the built-in leaf spring. The Self-Activated version begins expanding upon placement, requiring no manual adjustment.

Are Leaf Expanders comfortable for patients?

Yes. Leaf expanders apply gentle, continuous force, which often results in less discomfort compared to traditional screw-type expanders.

Can Leaf Expanders be used in mixed dentition cases?

Absolutely. They are ideal for younger patients and mixed dentition, offering early intervention with minimal compliance.

Do patients need to turn the expander at home?

No. One of the biggest advantages of leaf expanders is that they do not rely on patient activation, ensuring consistent force delivery.
