Star Glass Ceramic CAD-CAM Blocks ( Pack of 5 )

• High strength: With biaxial flexural strength ≥ 300 MPa and fracture toughness ≥ 2 MPa•m½, it meets thresholds often cited for single unit restorations (crowns, veneers). For instance, general literature suggests >300 MPa flexural strength is a benchmark for such materials.

• Ultra-thin veneer capability: Because it can be milled to as low as 0.2 mm, it supports minimally invasive preparations, preserving more natural tooth structure.

• Esthetic / optical choices: The availability of multiple translucency categories (HT, LT, MT, MO) allows tailoring to anterior vs posterior, masking needs, and substrate colours.

• Good physical properties: Hardness, density, low solubility, and controlled thermal expansion all point toward durability and compatibility in the oral environment.

• Compatible with digital workflow: As a CAD/CAM block it fits into modern digital restorative workflows (scan → design → mill → finish) — aligning with general CAD/CAM glass-ceramic advantages.

• Transmittance Options: HT, LT, MT, MO
• Radioactivity: Uranium-238 activity concentration ≤ 1.0 Bq/g (Safe for dental use)
