Palatal Expansion

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.

The RPE is typically used in phase I treatment to widen the arch, either before or during fixed treatment.

The HAAS appliance incorporates an acrylic plate within the vault of the palate with an expansion screw.

The Snap Lock Expander is designed to prevent unwinding of the screw.

The fan expander (fan RPE) allows for rapid expansion of the palate widening the arch of the anterior section while still maintaining the expansion at the molar level.

The Compact RPE is a low profile expander. With its compact body, it provides excellent stability and increased patient comfort.

Our Bonded RPE is made with the same Leone RPE, but any of our RPE’s can be used.  The appliance is built with a .036 framework around the lingual and buccal of the posterior teeth.

Our Bonded RPE is made with the same Leone RPE, but any of our RPE’s can be used. 

Taken from “The Mandibular E-Arch” by Neal Kravitz, the E-arch is a fixed, spring-loaded expander for slow expansion of the maxillary or mandibular arches.

The Williams Expander is used for lower expansion.

The RPE is typically used in phase I treatment to widen the arch, either prior or during fixed treatment.

The HAAS appliance incorporates an acrylic plate within the vault of the palate with an expansion screw. Lingual arms are laser welded to the 3D framework integrated into the acrylic.
