ISO Class 5 Dental Zirconia (SHT-ML), 1270-1330HV Hardness, 1500°C Optimized Sintering
Precision-Engineered for Minimal-Prep Dentistry
Meet SHT-ML – the ultra-translucent zirconia redefining conservative restorations. With 45% light transmission and 900MPa strength, this material enables 0.3mm marginal walls for maximum tissue preservation while delivering lifelike aesthetics. The optimized 9-shade system (A1-B1.4) captures subtle hue variations in anterior dentition, eliminating manual staining and reducing chairside time.
Surface Diffusion Layer:
Reduces light scattering at restoration surface
Depth Transmission Matrix:
Enhances incisal halo effect
Substrate Masking Core:
45% opacity hides dark preparations
ISO 13485-Certified Production
Veneers: 0.3mm margin integrity
Crowns: 98.4% Vita shade matching
Hybrid Abutments: Titanium masking
Inlays/Onlays: Feather-edge adaptation

Recommended sintering curve
(ST/ST-C/ST-ML/SHT/SHT-C/SHT-ML/UT-ML/3D-Pro-ML)
| Sintering temperature of ST/ST-C/ST-ML/SHT/SHT-C/SHT-ML is from 1500℃ to 1530℃,you should make sure peak temperature at this range. The recommended sintering temperature is 1500℃ Sintering temperature of UT-ML/3D-Pro-ML is from 1480℃ to 1510℃,you should make sure peak temperature at this range. The recommended sintering temperature is 1500℃ | ||
