CAD-CAM Anatomical Expander – Leone

CAD-CAM Anatomical Expander – Advanced Skeletal Anchorage Solution by Leone S.p.A.

The CAD-CAM Anatomical Expander by Leone S.p.A. represents a new generation of digitally designed orthodontic expansion devices created specifically for modern skeletal anchorage protocols. Engineered for precision, stability, and predictable clinical outcomes, the CAD-CAM Anatomical Expander is optimized for use with TAD-supported rapid palatal expansion procedures and offers exceptional adaptability for contemporary orthodontic workflows.

Designed using advanced CAD-CAM technology, the CAD-CAM Anatomical Expander differs significantly from traditional orthodontic expanders. Instead of conventional arms, this appliance incorporates two longitudinal square slots integrated directly into the body. These slots allow seamless laser welding with digitally designed support structures, ensuring maximum customization and accuracy for every clinical case. This innovative architecture makes the CAD-CAM Anatomical Expander especially suitable for digitally planned MARPE treatments and other skeletal anchorage applications in adult patients.

One of the most important advantages of the CAD-CAM Anatomical Expander is its compact and anatomically optimized design. The small body dimensions reduce patient discomfort while still delivering powerful and controlled expansion forces. Leone has integrated a unique self-centering guide system into the appliance, allowing smooth and reliable activation throughout the treatment process. Manufactured from high-quality biomedical stainless steel, the CAD-CAM Anatomical Expander provides outstanding resistance, long-term durability, and superior clinical reliability.

The appliance is specifically developed for skeletal anchorage on TADs, making it highly effective for difficult expansion cases where conventional tooth-borne appliances may not achieve stable results. Orthodontists can digitally design hybrid expanders that combine both dental and skeletal anchorage, or fully skeletal expanders for enhanced orthopedic control. This flexibility makes the CAD-CAM Anatomical Expander an excellent solution for treating transverse maxillary deficiencies in adolescents and adults.

The CAD-CAM Anatomical Expander is available in multiple expansion capacities to accommodate different treatment requirements. According to the product specifications shown in the catalogue, Leone offers three versions:

• 8 mm expansion capacity
• 10 mm expansion capacity
• 12 mm expansion capacity

All models feature a body width of 4.5 mm and a front view dimension of 6 mm, ensuring a compact intraoral profile while maintaining structural rigidity. The activation arm diameter is 0.8 mm, supporting precise and controlled expansion mechanics. Depending on the selected model, the maximum expansion limits are:

• 40 activations for the 8 mm version
• 50 activations for the 10 mm version
• 60 activations for the 12 mm version

These specifications make the CAD-CAM Anatomical Expander highly versatile for different anatomical situations and orthodontic treatment plans.

Another major advantage of the CAD-CAM Anatomical Expander is its compatibility with fully digital orthodontic workflows. Modern orthodontic laboratories increasingly rely on intraoral scans, CAD software, and laser welding systems to fabricate customized appliances. The CAD-CAM Anatomical Expander integrates perfectly into this environment, enabling efficient digital production with exceptional fitting accuracy. The STL file for the appliance is available through Leone and included in the 3DLEONE DESIGNER software library, simplifying the appliance design process for orthodontic professionals and laboratories.

The package includes:

• 1 stainless steel key
• 1 hinged enhanced-key with handle
• Patient instructions for at-home activation

This complete package ensures convenient clinical handling and easier patient management during the activation phase of treatment.

Clinically, the CAD-CAM Anatomical Expander is ideal for rapid maxillary expansion protocols where skeletal effects are prioritized over purely dental movement. By using TAD-supported anchorage, clinicians can reduce undesirable tooth tipping and improve orthopedic expansion outcomes. This is particularly valuable in adult MARPE therapies where suture resistance is significantly greater than in younger patients.

The compact geometry and precision manufacturing of the CAD-CAM Anatomical Expander also contribute to improved oral hygiene and patient comfort compared to bulkier traditional expanders. Its streamlined profile minimizes irritation while preserving the strength necessary for effective skeletal expansion.

For orthodontists and dental laboratories seeking a digitally optimized skeletal expander, the CAD-CAM Anatomical Expander offers an outstanding combination of innovation, precision engineering, and clinical versatility. Whether used for hybrid expansion appliances or fully skeletal MARPE systems, this Leone device provides reliable expansion mechanics and seamless integration into modern CAD-CAM orthodontic production workflows.

With its advanced self-centering mechanism, biomedical stainless steel construction, compact anatomical design, and digital compatibility, the CAD-CAM Anatomical Expander stands as a premium solution for modern orthodontic expansion therapy.
