OnePro Dental ST Pre-shaded Zirconia Disc is designed for professional dental CAD/CAM milling workflows where laboratories need a balance of strength, translucency, and efficient shade matching.

Unlike ST White zirconia, ST Pre-shaded Zirconia comes with pre-integrated shade options, helping laboratories reduce manual staining steps and achieve more consistent color results for everyday crown-and-bridge production.

Available in a 98mm open-system format, multiple thicknesses, and 20 popular shades, it is a practical zirconia solution for labs producing anterior crowns, posterior crowns, 3–4 unit bridges, and daily esthetic restorations.

Why Dental Labs Choose ST Pre-shaded Zirconia

Designed for laboratories that want balanced zirconia performance, ready-to-use shades, and a more efficient daily production workflow.

  • Pre-shaded Convenience

    The shade is already integrated into the zirconia material, helping laboratories reduce manual staining steps and simplify daily production.

  • Balanced Strength & Translucency

    With up to 1200 MPa flexural strength and approximately 43% translucency, ST Pre-shaded Zirconia is suitable for a wide range of anterior and posterior restorations.

  • Consistent Shade Results

    Factory-controlled pre-shading helps provide more predictable and repeatable shade results compared with fully manual staining workflows.

  • 20 Popular Shade Options

    Available in 16 common VITA-style shades and 4 bleach shades to support natural tooth colors and whitening cases.

ST Pre-shaded Zirconia for Efficient Daily Restorations

ST Pre-shaded Zirconia is developed for dental laboratories that need reliable zirconia performance with a simplified shade workflow.

It offers the same balanced positioning as ST White zirconia, but with pre-integrated shade options. This makes it especially useful for laboratories that frequently produce standard shade restorations and want to reduce manual staining variation.

For daily crown-and-bridge cases, ST Pre-shaded Zirconia helps technicians move from milling to sintering and final finishing with fewer shade adjustment steps. It is a practical choice for laboratories that value production efficiency, shade consistency, and dependable mechanical performance.

  • Pre-shaded zirconia for simplified shade workflow
  • Suitable for anterior and posterior restorations
  • Balanced strength and translucency for daily cases
  • Useful for laboratories with repeated standard shade demand
  • Available in multiple shades and thicknesses

Available Shade Options

Choose from 20 pre-shaded options to support common natural tooth shades and bleach-shade cases.

Shade Group Available Shades Typical Use
A Series A1, A2, A3, A3.5, A4 Common natural tooth shades
B Series B1, B2, B3, B4 Brighter yellowish shade cases
C Series C1, C2, C3, C4 Grayish shade cases
D Series D2, D3, D4 Reddish-gray shade cases
BL Series BL1, BL2, BL3, BL4 Bleach and whitening cases

Total: 20 pre-shaded options, including 16 commonly used natural shades and 4 bleach shades. For highly customized shade characterization, additional surface stain or glaze can still be applied according to the laboratory workflow.

Recommended ST Pre-shaded Zirconia Workflow

  1. Select the required pre-shaded color and disc thickness according to the restoration design.
  2. Design the restoration in CAD software based on the required restoration type, connector design, and occlusal clearance.
  3. Nest the restoration properly in the 98mm zirconia disc and confirm the correct milling strategy.
  4. Mill the restoration using a zirconia-compatible CAD/CAM milling system and validated milling parameters.
  5. Clean the milled restoration carefully and remove zirconia dust before sintering.
  6. Sinter according to the recommended furnace program and the batch-specific instructions.
  7. Apply surface stain or glaze only if additional characterization or final shade adjustment is required.
  8. Finish, polish, and inspect the final restoration before delivery.

What is ST Pre-shaded Zirconia best used for?

ST Pre-shaded Zirconia is best used for dental laboratories that need balanced zirconia strength, esthetics, and ready-to-use shade options for everyday crown-and-bridge restorations.

What is the difference between ST Pre-shaded and ST White Zirconia?

ST Pre-shaded Zirconia has the shade integrated into the material, while ST White Zirconia is a white base designed for manual staining. ST Pre-shaded is more convenient for standard shade cases, while ST White offers more flexible custom shade control.

How many shade options are available?

ST Pre-shaded Zirconia is available in 20 shade options, including A1, A2, A3, A3.5, A4, B1, B2, B3, B4, C1, C2, C3, C4, D2, D3, D4, BL1, BL2, BL3, and BL4.

Do I need to stain ST Pre-shaded Zirconia before sintering?

For many standard shade cases, manual staining before sintering can be reduced because the base shade is already integrated into the material. However, laboratories may still apply additional characterization according to their own workflow.

Can I still apply surface stains or glaze?

Yes. Surface stains and glaze can still be applied after sintering when additional characterization, surface finish, or final shade adjustment is required.

What is the flexural strength of ST Pre-shaded Zirconia?

ST Pre-shaded Zirconia offers up to 1200 MPa flexural strength, making it suitable for a wide range of anterior and posterior restorations.

Is ST Pre-shaded Zirconia suitable for anterior restorations?

Yes. With approximately 43% translucency and multiple pre-shaded options, ST Pre-shaded Zirconia can be used for anterior crowns where balanced strength and esthetics are required. For cases requiring higher translucency, SHT, UT, or 3D Pro may be considered.

Can ST Pre-shaded Zirconia be used for posterior crowns and bridges?

Yes. ST Pre-shaded Zirconia is suitable for posterior crowns and selected bridge restorations when the restoration design, connector dimensions, occlusal load, and professional assessment support its use.

Which CAD/CAM systems are compatible?

The 98mm open-system format is compatible with many open dental CAD/CAM milling systems configured for zirconia disc processing.

Can you provide CE and FDA-related documentation?

Yes. CE and FDA-related documentation can be provided for review when applicable. Please contact our team before ordering if your laboratory requires specific certificates, batch information, or technical documentation.
