B40 High Translucency Lithium Disilicate Blocks Cubes for Cerec Chairside Milling

Achieve outstanding anterior aesthetics with these B40 high translucency (HT) lithium disilicate blocks cubes, purpose-built for Sirona Cerec CAD/CAM chairside milling systems. The B40 shade delivers a warm, natural tooth color with exceptional light transmission through the restoration body. Supplied in a 4-piece pack, each block mills into a single restoration that crystallizes to over 400 MPa flexural strength in one fast furnace cycle.

Key Features & Benefits

• Premium Translucency: B40 HT lithium disilicate produces vibrant, chameleon-like restorations that adapt to the color of adjacent natural teeth for a seamless smile.
• Warm B-Shade Palette: The B40 color sits in the warm yellow-red spectrum, matching patients with naturally warm dentition beautifully.
• Robust Mechanical Properties: Flexural strength of ≥ 400 MPa combined with a fracture toughness of ≥ 1 MPa·m½ provides clinical peace of mind.
• Quick Crystallization: Single-stage firing program with a final temperature of 840°C completes within 20 minutes for maximum chairside efficiency.
• Excellent Polishability: Achieves a high-gloss surface through mechanical polishing alone, though stain and glaze finishing is also fully supported.
• Broad System Compatibility: Designed for Cerec MCXL, MCX5, and Primemill, and adaptable to laboratory wet milling platforms from leading manufacturers.
• Certified Biocompatibility: Meets all ISO 10993 biological safety requirements, including cytotoxicity, genotoxicity, and implantation testing.

Technical Specifications

Clinical Applications

• Anterior Veneers: Maximum translucency creates depth and vitality in veneer restorations where natural appearance is paramount.
• Single Anterior Crowns: B40 HT excels in the aesthetic zone, reproducing the opalescence and fluorescence of natural enamel.
• Inlays and Onlays: Conservative preparations benefit from the material's combination of strength and aesthetic integration.
• Partial Coverage Restorations: Ideal for table tops and overlay designs where blending with remaining tooth structure is critical.

Compatible Milling Machines

B40 HT blocks are optimized for Sirona Cerec MCXL and MCX5 chairside units. For laboratory workflows, they are compatible with wet milling systems from Amann Girrbach Ceramill, Zirkonzahn, and IMES ICORE. View all available options in our lithium disilicate blocks cubes category.

Frequently Asked Questions

Q: What makes B40 HT different from other HT shades?
A: B40 sits in the warm yellow-red portion of the Vita shade spectrum. Compared to cooler A-shades, B40 produces restorations with a warmer undertone, making it the preferred choice for patients with naturally warm-toned teeth.

Q: Can I stain and glaze B40 HT after crystallization?
A: Absolutely. While the material polishes to a high luster mechanically, you can apply compatible stain and Lithium disilicate for detailed characterization of surface effects, incisal translucency, and check-line simulation.

Q: Is HF etching required before cementation?
A: Yes. Hydrofluoric acid etching (5% for 20 seconds) followed by silanization is the recommended surface treatment protocol for achieving maximum bond strength with resin cements.

Q: What is the shelf life of these blocks?
A: Lithium disilicate blocks cubes have an indefinite shelf life when stored properly in a cool, dry environment in their original sealed packaging.

Q: Are color samples or trial blocks available?
A: Contact CADBURS customer support for shade sample requests. Our team can help you select the ideal shade and translucency combination for your clinical needs.
