Buyer's Guide

How to Choose Zirconia Disc System for Your Dental Lab

Dental zirconia discs are the backbone of modern monolithic and layered restorations. Choosing the right translucency and strength grade β€” from ultra-high-strength HT-Plus (1350 MPa) to ultra-translucent UT (49% light transmission) β€” determines both aesthetics and long-term clinical success for crowns, bridges and full-arch work.

πŸ’ŽHow to choose zirconia grade

  • Anterior aesthetics: use UT or 3D-Pro-ML multilayer for natural shade gradient and high translucency.
  • Posterior function: HT-Plus (up to 1350 MPa) for bridges and multi-unit cases.
  • Monolithic full-contour: recommended for posterior to avoid chipping.
  • Open-system blanks: 98.5 mm / 95 mm with standard hole patterns fit most CAD/CAM mills.

πŸ”₯Sintering & handling

  • Typical full cycle 1450-1500Β°C with controlled ramp and cool.
  • AI-S8 supports fast sintering in 30-45 min β€” validate on a test batch first.
  • Store discs dry; avoid thermal shock between cycles.
  • Use a calibrated pyrometer to keep shrinkage consistent.

🦷Typical applications

  • Single crowns, inlays/onlays and veneers.
  • Implant-supported bridges and multi-unit frameworks.
  • Full-contour posterior and anterior restorations.
  • Long-span bridges where high strength is required.

FAQ

Product FAQ

Which zirconia grade should I choose for anterior vs posterior?
Use high-translucency UT/3D-Pro-ML for anterior aesthetics, and high-strength HT-Plus (up to 1350 MPa) for posterior bridges and multi-unit cases. Monolithic full-contour is recommended for posterior function.
Are Birfair zirconia discs open-system compatible?
Yes. Our discs are sized for standard open CAD/CAM mills and are compatible with major systems; confirm blank size (98.5 mm / 95 mm) and hole pattern with your mill before ordering.
What sintering profile do you recommend?
A typical full-cycle profile is 1450-1500Β°C with controlled ramp and cool. For fast sintering, our AI-S8 supports 30-45 min cycles β€” always validate with a shrinkage/spacing test on your first batch.
