Optimized for Digital Orthodontic Workflows

Designed for reliable and controlled palatal expansion, the Rapid CAD-CAM Expander features four transversal housings integrated directly into the body of the screw. Unlike conventional expanders that rely on arms, this advanced CAD-CAM design enables perfectly oriented coupling with digitally manufactured frameworks. This ensures an optimal laser welding process while improving the overall structural integrity of the appliance. For dental laboratories utilizing digital orthodontic workflows, the Rapid CAD-CAM Expander provides an efficient and highly accurate solution for fabricating modern rapid palatal expanders.

One of the biggest advantages of the Rapid CAD-CAM Expander is its seamless compatibility with CAD-CAM and SLM technologies. As digital orthodontics continues to evolve, laboratories and orthodontists increasingly require components that integrate smoothly into digital production systems. Leone designed this expander specifically for that purpose, allowing clinicians to maintain the trusted clinical performance of conventional expanders while benefiting from the precision and efficiency of digital manufacturing.

Precision Engineering and Laser Marking

The Rapid CAD-CAM Expander is manufactured using high-quality materials and incorporates laser-marked indicators directly on the screw body. The expansion capacity in millimeters, directional activation arrow, and lot number are permanently laser engraved for easy identification and improved traceability. This practical feature helps clinicians monitor treatment progress while simplifying appliance management inside both laboratories and orthodontic clinics.

The compact body design also improves patient comfort while maintaining excellent mechanical strength during expansion procedures. The optimized geometry supports accurate force distribution and consistent activation throughout treatment.
