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.

The Leaf RPE will be pre-activated upon arrival being held closed by a ligature wire. After insertion, clip the ligature wire to activate the appliance. The deactivated leaf springs will show the past expansion.
This appliance should be cleaned every day with toothpaste and a soft toothbrush, morning and night. Encourage the patient to give sufficient time to clean thoroughly around the appliance, gums, teeth, and bands to maintain proper hygiene and prevent inflammation. 3 minutes is recommended.
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.
