AUDENTAL 3D PRO 20 mm multilayer zirconia disc - CE
The AUDENTAL 3D PRO 20 mm zirconia disc is designed for dental laboratories looking for a reliable, aesthetic and versatile pre-shaded multilayer zirconia for daily CAD/CAM production workflows.
This 20 mm thickness provides additional usable height for larger restorations while maintaining the ideal balance between translucency, mechanical strength and material homogeneity.
20 mm dental zirconia: applications and advantages for the laboratory
Multilayer zirconia for dental laboratories has become a key material in fixed CAD/CAM prosthetics. It enables the production of reliable monolithic restorations with excellent stability and a more natural appearance than conventional monochromatic zirconia.
In this 20 mm version, the AUDENTAL 3D PRO disc is especially suitable for laboratories requiring additional material height to optimize nesting, large bridges and more demanding restorations.
For the laboratory, the objective remains clear: improve productivity, maintain consistent monolithic aesthetics and reduce layering procedures while preserving reliable milling behavior.
Strength suitable for extensive restorations
The material provides mechanical performance suitable for single restorations, bridges and more extensive restorations when the prosthetic design and sintering protocol are correctly validated.
Natural multilayer aesthetics
The progressive transition of shade and translucency helps achieve a more natural monolithic result with reduced characterization requirements for everyday restorations.
A key advantage: the ability to produce full-arch bridges with a 20 mm disc height
Many multilayer zirconias are promoted for their aesthetics but remain mechanically limited when restorations become larger or more demanding.
With AUDENTAL 3D PRO 20 mm, the material is designed to go further: this version provides additional usable height while maintaining a structure suitable for manufacturing full-arch bridges when the production protocol is properly controlled.
This capability is based on material quality, density homogeneity, post-sintering stability and the use of true isostatic pressing.
Why isostatic pressing improves stability
Isostatic pressing applies uniform pressure in all directions in order to achieve a more consistent density throughout the entire disc.
For the dental laboratory, this results in more consistent milling behavior, improved post-sintering stability and enhanced reliability for extensive restorations.
A more demanding and controlled manufacturing process
Isostatic pressing requires more advanced industrial equipment and stricter quality control procedures than conventional compaction methods.
In return, the laboratory benefits from a more homogeneous, stable and reliable material better suited to highly demanding technical restorations.
Milling and inspection of pre-sintered zirconia
Pre-sintered zirconia should be processed in a clean environment with efficient extraction, proper lighting and regular visual inspection.
Inspecting connectors, cervical areas and thin sections under magnification helps identify potential micro-chipping or milling defects before sintering.
Characterization and finishing
Although pre-shaded, AUDENTAL 3D PRO zirconia can still be customized using stains, coloring liquids or glazes compatible with the laboratory protocol.
This approach preserves the productivity advantages of multilayer zirconia while allowing additional aesthetic customization when clinically required.

Recommended sintering curve
Strict compliance with the sintering curve is essential to achieve the final density, dimensional stability and mechanical performance expected from the AUDENTAL 3D PRO 20 mm disc.
Excessively rapid heating, incorrect holding stages or poorly controlled cooling may affect the final quality of the restoration.
| Initial heating | 10 °C/min up to 900 °C |
|---|---|
| First hold | 900 °C for 30 min |
| Intermediate heating | 3 °C/min up to 1300 °C |
| Second hold | 1300 °C for 10 min |
| Final heating | 3 °C/min up to 1490 °C |
| Main hold | 1490 °C for 120 min |
| Controlled cooling | -8 °C/min down to 300 °C |
| End of cycle | Natural cooling to room temperature |
This curve should always be validated according to the recommendations of the sintering furnace manufacturer, the load configuration, restoration geometry and the laboratory’s internal protocol.
Important sintering recommendations
- Follow the recommendations of the sintering furnace manufacturer.
- Use zirconia-compatible sintering trays.
- Prefer medium zirconia beads, approximately 1.6 to 2 mm.
- Use approximately 2 mm of beads inside the tray.
- Leave sufficient space between restorations to ensure homogeneous thermal diffusion.
Proper furnace loading directly contributes to dimensional stability, surface integrity and final restoration reliability.
CE certification and professional safety
The Audental brand benefits from genuine CE certification, an important point for materials intended for demanding prosthetic restorations.
This compliance should not be viewed solely as an administrative argument. It also reflects material control, manufacturing consistency and industrial process quality.
For the dental laboratory, working with a CE-certified material provides additional reassurance regarding professional responsibility.

Technical FAQ & laboratory recommendations
How can cracks or chipping after sintering be avoided?
Strict compliance with the sintering curve is essential. Excessively rapid heating or sudden cooling may create internal stresses.
It is recommended to use zirconia beads from 1.6 to 2 mm, with approximately 2 mm bead height inside the tray and adequate spacing between restorations.
Why choose 20 mm thickness instead of 18 mm?
The 20 mm thickness provides additional vertical height for prosthetic cases requiring more usable volume, especially when optimizing nesting inside the disc.
It can be particularly useful for certain bridges, large posterior restorations or morphologies requiring increased vertical clearance before milling.
What working conditions are recommended for pre-sintered zirconia?
Pre-sintered zirconia should be processed in an enclosed environment with efficient extraction to reduce fine dust exposure.
Proper lighting and magnification inspection help identify milling defects before sintering.
Can the shade be customized after milling?
Yes, the zirconia can be customized using stains, coloring liquids or compatible glazing systems.
This stage allows adjustment of saturation, cervical effects and incisal characterization according to the laboratory workflow.
Why use dedicated zirconia sintering beads?
Zirconia beads ensure stable and homogeneous support during the sintering cycle.
Excessively fine beads may become trapped in certain prosthetic areas and compromise final accuracy.
What are the best practices for optimal aesthetic results?
Use burs specifically designed for pre-sintered zirconia, thoroughly clean the restoration and respect drying cycles when applying coloring liquids.
After sintering, adjustments should be carried out using compatible instruments and verified under neutral lighting conditions.
