Fixed Appliances, Palatal Expansion

Leaf Spring Self 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.

The metal framework is 3D printed for the most predictable and accurate fit.  The simple two appointment process starts with a scan at appointment one and then delivery on the following date.  No need for separators.

Reference

The Leaf expander is featured in the 2018 March edition of the JCO.  Click here to view a copy of the article on the JCO website.

Our skilled digital technicians can help you conceptualize a design that provides maximum retention for the appliance.  Metal can be designed that runs snug to the lingual with exact fitting rests over the occlusion.  Options are available to cup the lingual and the buccal.  This revolutionary technology will change the way you serve your patients.
