ST Color Zirconia Blocks 1400 MPa Pre-Shaded A1-D4 98.5mm For Dental Crowns Bridges

The ST Color Zirconia Block combines exceptional 1400 MPa flexural strength with the convenience and color consistency of pre-shaded zirconia. Available in a comprehensive range of VITA classical shades (A1-D4) and bleach shades (BL1-BL4), it eliminates the need for manual staining of the core structure, streamlining the workflow for dental laboratories. This block is engineered for demanding restorations where both supreme strength and efficient, predictable aesthetics are required.

• Pre-Shaded for Efficiency: Ready-to-use in multiple shades, saving time and ensuring color consistency.
• Ultra-High Strength: 1400 MPa flexural strength guarantees reliability for long-span bridges and full arches.
• Comprehensive Shade Range: Covers VITA classical A1-D4 and popular bleach shades BL1-BL4.
• Optimized Workflow: Ideal for monolithic restorations or as a perfectly colored base for veneering.
• Excellent Milling Performance: Ensures precise and chipping-free processing in CAD/CAM systems.

1. What is the main benefit of using a pre-shaded zirconia block?
The primary benefit is workflow efficiency and color consistency. It removes the variability and time required for manual staining of the zirconia core, ensuring that the base color is uniform and accurately matches the desired shade guide from the start.

2. Is the final color of the restoration stable after sintering?
Yes. The colorants in ST Color blocks are thermally stable and integrated into the zirconia matrix during the manufacturing process. When sintered according to the recommended program, they provide a consistent and stable final color that matches the designated VITA shade.

3. Can this block be used for monolithic anterior restorations?
While it possesses high strength, its 40% translucency is suitable for monolithic anterior crowns, especially where higher opacity is desired or for specific aesthetic designs. For the most lifelike translucency in monolithic anteriors, our multilayer series might be preferred, but ST Color offers an excellent balance of strength, efficiency, and adequate aesthetics.
