SHT Dental Zirconia Block , Pre-Stained 26 Shade Options , Fast Chairside Restorations

Streamline your lab workflow with the SHT Zirconia Block – optimized for single-visit restorations. Its white base material accepts 16/26 shade staining liquids with minimal absorption time (5-7 minutes), while the recommended 1500°C sintering temperature ensures 2-hour turnaround. With 46% translucency matching natural dentin, technicians achieve lifelike layering without multiple firing cycles.

Workflow Benefits
• Staining Efficiency: Dilution liquid allows precise saturation control
• Milling Precision: 92×75mm mini-blocks for economical single-crown cases
• Sintering Reliability: ±0.01 g/cm³ density consistency prevents distortion

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
