The Story
The Leone Fan-Type Rapid Expander is an orthodontic expansion screw designed for rapid maxillary expansion (RME), particularly targeting the anterior portion of the maxillary arch. Its fan-shaped opening mechanism allows greater expansion in the front of the palate while maintaining minimal expansion in the posterior molar area.
Manufactured from biomedical stainless steel, the expander provides durability, precise activation, and reliable orthodontic results. The expanding arms are laser-welded to the screw body for strong structural stability and consistent expansion control.
