High-Strength SHT Zirconia Block

Product Description
High-Strength SHT Zirconia Block , 1000MPa for Molar Bridges , ISO Class 5 Certified

Designed for high-stress posterior regions, the SHT Zirconia Block delivers 1000MPa flexural strength – sufficient for 4+ unit bridges. Its 5.7 MPa·m¹ᐟ² fracture toughness outperforms conventional zirconia (industry average: 4.5-5.2), resisting chipping under 300N occlusal forces. Accelerated aging tests confirm <5% monoclinic phase retention after 20-year simulation.

Engineering Breakthroughs

  • Y₂O₃ Stabilization: 7.0-7.8% yttria content prevents low-temperature degradation

  • Thermal Stability: CTE (10.5±0.5)×10⁻⁶/K matches natural dentition

  • Impurity Control: <0.15% Al₂O₃ ensures crack resistance

Bridge Performance Data

Test Result
Chewing Simulation >500,000 cycles (0 fail)
Marginal Fit <60μm discrepancy
Wear Resistance 0.05mm/year loss

Certifications

  • ISO 6872:2015 Class 5

  • FDA 510(k) Cleared

  • CE Marked
