Micro Rapid CAD-CAM Expander 8mm – Leone

Easy Access Micro Expander Tooth Borne by Leone

The Micro Rapid CAD-CAM Expander by Leone S.p.A. is a modern orthodontic expansion screw developed specifically for digital orthodontic workflows and CAD-CAM fabricated appliances. Designed for tooth-borne expanders, this compact device combines Leone’s trusted orthodontic engineering with advanced CAD-CAM compatibility, offering dental laboratories and orthodontists a highly precise and efficient solution for digitally manufactured rapid palatal expanders.

The Micro Rapid CAD-CAM Expander is the optimized CAD-CAM evolution of the well-known Stealth Easy Access system. Instead of traditional arms, the expander incorporates two transversal housings with ending stops on the body. This innovative configuration allows perfectly oriented coupling with digitally designed and SLM-manufactured frameworks, ensuring an accurate and reliable laser welding process. As digital orthodontics becomes increasingly important in modern dental laboratories, the Micro Rapid CAD-CAM Expander provides an ideal balance between compact dimensions, reliable mechanics, and streamlined CAD-CAM integration.

Compact Design for Improved Patient Comfort

One of the key advantages of the Micro Rapid CAD-CAM Expander is its extremely compact structure. The reduced size makes it especially suitable for cases where space is limited or where a smaller appliance is preferred for improved patient comfort and easier adaptation.

According to the catalogue specifications, the appliance dimensions are:

• Front view width: 4.95 mm
• Back view height: 4.05 mm

Despite its compact design, the expander maintains excellent mechanical stability and delivers controlled orthodontic expansion forces throughout treatment.

The visible screw hole-head design also improves intraoral activation accessibility. This allows orthodontists and patients to activate the appliance more easily using the supplied swivel key with handle. The simplified activation process contributes to improved patient compliance and more predictable treatment progress.

Optimized for CAD-CAM and Digital Orthodontics

The Micro Rapid CAD-CAM Expander has been specifically engineered for digital orthodontic manufacturing systems. Conventional expansion screws often require manual soldering and positioning procedures that can introduce inaccuracies into appliance fabrication. Leone addressed these limitations by creating an expander that integrates directly into CAD-CAM workflows.

The transversal housings on the body allow stable positioning within digitally designed frameworks, while the optimized geometry supports precise laser welding with SLM-manufactured structures. This makes the Micro Rapid CAD-CAM Expander highly suitable for orthodontic laboratories transitioning toward fully digital production methods.

STL files for the appliance are available through Leone’s website and are also integrated into the 3DLEONE DESIGNER software library. This enables dental technicians to incorporate the expander directly into digital appliance designs with outstanding precision and workflow efficiency.

Reliable Orthodontic Expansion Performance

The Micro Rapid CAD-CAM Expander is recommended for dental anchored and tooth-borne expansion appliances. Leone designed this expander to preserve all the successful characteristics of their classic globally recognized expansion systems while adapting the appliance for modern CAD-CAM production techniques.

The screw body includes laser-marked indicators showing:

• Expansion capacity in millimeters
• Directional activation arrow
• Lot number for traceability

These laser markings improve usability for clinicians and simplify appliance management during orthodontic treatment.

The smooth activation mechanism of the Micro Rapid CAD-CAM Expander ensures controlled and predictable expansion forces throughout the treatment process. Orthodontists can therefore achieve reliable orthopedic and orthodontic results while benefiting from the precision offered by digital manufacturing workflows.
