LEAF RPE

Leaf RPE

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 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.

Description

Treatment & Care

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. Schedule the patient a month out in order reload the springs by using the provided key to close the springs turning front to back. Once it’s reloaded, additional expansion will be produced. Note: The majority of the expansion will occur within the first week as the amount of force is greatest upon the initial 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.
