Fixed Appliances, Palatal Expansion

Leaf Spring Activated Expander

The Leaf Spring Activated Expander from Leone is an evolution in design from the spring-loaded expander, designed with the technical and scientific collaboration of Dr. Claudio Lanteri and Mr. Filippo Francolini. Its small size body and two Nickel Titanium Memoria® leaf springs allow the release of calibrated and continuous forces to promote the dental expansion of the maxillary arch. Re-loading is needed when the two opposing leaf springs move apart. The intraoral activation will put the springs in contact again. Available in both 6 and 9mm of expansion and 450 grams and 900 grams of force. With each expansion appliance, we provide a custom swivel key that has an integrated activation recording tool directly on the handle.
