DEPRAG Gemstone ST Zirconia Disc
The DEPRAG ST Zirconia Disc (Super Translucent) is engineered for outstanding mechanical performance and structural reliability in demanding dental restorations. Offering a flexural strength of 1250 MPa and 42% translucency, it provides the ideal balance of durability and natural esthetics.
Crafted with high-purity Tosoh zirconia powder, the ST Disc ensures excellent color accuracy, uniform density, and exceptional resistance to fracture — making it ideal for posterior crowns, long-span bridges, and full-arch restorations.
Its precise microstructure supports both fast and conventional sintering (as quick as 88 minutes), maintaining dimensional stability and consistent results across all CAD/CAM systems.
- High strength up to 1250 MPa for long-span bridges and frameworks
- 42% translucency for a natural yet strong appearance
- Full VITA 16 + 4 Bleach shade range
- Compatible with 98 mm / 95 mm / 92 × 75 mm disc systems
- Supports both normal and fast sintering cycles
- Ideal for full-contour crowns, posterior restorations, and implant frameworks
