Recommended ST White Zirconia Workflow

  1. Design the restoration in CAD software according to the required restoration type and connector design.
  2. Select the correct 98mm disc thickness based on restoration height, nesting layout, and required material support.
  3. Mill the restoration using a zirconia-compatible CAD/CAM strategy.
  4. Clean the milled restoration carefully and remove residual zirconia dust.
  5. Apply zirconia coloring liquid if customized shade matching is required.
  6. Dry the restoration according to the coloring-liquid workflow before sintering.
  7. Sinter according to the recommended furnace program and batch-specific instructions.
  8. Finish, polish, stain, or glaze according to the final esthetic requirement.
  9. Inspect the fit, margins, occlusion, connectors, and final surface condition before delivery.

How to Choose the Right Zirconia Disc

  • Choose ST for Balance

    Identify whether the case is a single crown, bridge, full-arch restoration, veneer, or complex esthetic case.

  • Choose White for Custom Shading

    Choose a white zirconia base when your laboratory prefers customized staining and glazing workflows after milling.

  • Confirm the Thickness

    Select the disc thickness according to restoration height, nesting layout, occlusal clearance, and connector design.

  • Match the Restoration Type

    For high-load posterior or long-span bridge cases, consider HT White. For higher esthetics, consider SHT, UT, or 3D Pro.

What is ST White Zirconia best used for?

ST White Zirconia is best used for dental laboratories that need a balanced zirconia material for anterior crowns, posterior crowns, 3–4 unit bridges, inlays, onlays, and general daily CAD/CAM restorations.

What is the flexural strength of ST White Zirconia?
