Chinese Dental Lab High Flexural Strength Metal-Free Dental Zirconia Full Zirconia Crown with CAD/CAM Milling
Dental Lab Zirconia Full Zirconia Crowns, referred to as either full-contour or monolithic zirconia, represent modern metal-free restorations composed solely of zirconium dioxide (ZrO₂). Unlike porcelain-fused-to-metal or layered alternatives, these restorations do not require a ceramic veneer, providing a consistent and highly durable structure.
Key Features
Exceptional Strength: With a flexural strength of 800-1,200 MPa, full-contour zirconia is one of the strongest dental materials available. Ideal for posterior crowns and bridges, especially in patients with bruxism or high occlusal loads.
Superior Biocompatibility: Zirconia is hypoallergenic, corrosion-resistant, and does not cause metal ion release or gum discoloration, making it suitable for patients with metal allergies.
Aesthetic Versatility: Modern multilayer zirconia discs offer gradient shade and translucency (e.g., high-translucency for anterior teeth, high-strength for posteriors). Digital staining and glazing techniques further enhance natural appearance.
Wear-Friendly to Opposing Teeth: When properly polished or glazed, monolithic zirconia is smooth and causes minimal wear to natural enamel compared to rough or unpolished ceramics.
CAD/CAM Compatibility: Full-contour zirconia is fabricated via computer-aided design and manufacturing (CAD/CAM), ensuring precision fit, efficiency, and reproducibility.
Clinical Applications
Single crowns (posterior and anterior)
Short-span bridges (up to 3-4 units)
Implant abutments and hybrid restorations
Splinted crowns for bruxism cases
Full-contour or monolithic zirconia represents the pinnacle of modern metal-free dental restorations. Composed entirely of zirconium dioxide (ZrO₂), this innovative material eliminates the need for ceramic veneers found in porcelain-fused-to-metal or layered alternatives, resulting in a consistently strong and durable dental solution.
