SHT-C Zirconia Block , High Translucency 45% , 900MPa Strength for Aesthetic Dental Crowns

SHT-C Zirconia Block , High Translucency 45% , 900MPa Strength for Aesthetic Dental Crowns
The SHT-C Zirconia Block represents a breakthrough in dental restorative materials, engineered for superior aesthetics and durability. With 45% translucency matching natural teeth, it eliminates the "gray gum line" effect and ensures seamless integration. Its 900MPa flexural strength exceeds ISO 6872 Class 5 requirements (800MPa minimum), making it ideal for full-contour crowns in high-stress molar regions. The material’s low monoclinic phase content (<5% after aging) guarantees long-term stability, while 0-level cytotoxicity and <0.1 Bq/g radioactivity prioritize patient safety.

Key Characteristics
Optical Performance: 45% translucency (at 1.0mm thickness) provides lifelike aesthetics.
Mechanical Superiority: 5.7 MPa·m¹ᐟ² fracture toughness resists chipping.
Biocompatibility: Passes ISO cytotoxicity tests, preventing gum inflammation.
Efficient Processing: Pre-sintered blocks (98/95/92×75mm) enable precise CAD/CAM milling

Applications
Designed for monolithic full-contour crowns, the SHT-C eliminates layered porcelain work. Its 5 optimized shades (A1, A2, A3, B1, B2) leverage high translucency in light-color zones, perfect for anterior restorations. Unlike traditional metal-ceramic crowns, it offers:

  • Zero X-ray interference for clear medical imaging.

  • Minimal tooth preparation, preserving natural structure.

  • Acid resistance and low chemical solubility (<100 µg/cm²).

Quality Assurance
Produced via cold isostatic pressing (CIP) and strict pre-sintering protocols, each block ensures uniform density (3.15±0.05 g/cm³ pre-sintering). Our manufacturing complies with ISO 6872:2015, validated by third-party labs.
