Product Description

High-Strength ST Zirconia , 1200MPa for Multi-Unit Bridges , ISO Class 5 Certified
Engineered for demanding posterior applications, ST's 1200MPa flexural strength supports 4+ unit bridges with 500,000+ chewing cycle durability. The 6.5 MPa·m¹ᐟ² fracture toughness prevents marginal chipping, while <15% monoclinic phase ensures decade-long stability in wet environments.

Bridge Performance Metrics

Test Result
Load Resistance 1500N (molar zone)
Marginal Accuracy <60μm discrepancy
Wear Rate 0.03mm/year

Clinical Validation

  • 0% framework fractures in 3-year study (n=500 bridges)

  • 98.2% survival rate at 5-year recall

  • Compatible with all major cement systems

ST/SHT/SHT-ML Sintering
Max Heating rate: 10℃ per minute Final temperature: 1500℃-1550℃, 1530℃ is best
Holding time at final temperature: 2 hours
Cooling should be done without temperature control in closed furnace
Never open the furnace before it has reached a temperature of less than 80℃ to avoid thermal shocks
