AUDENTAL 3D PRO 16 mm Multilayer Zirconia Disc for Dental Laboratories
Référence: AUD016A2
AUDENTAL 3D PRO multilayer zirconia disc - CE
The AUDENTAL 3D PRO zirconia disc is designed for dental laboratories looking for a reliable, aesthetic and truly versatile pre-shaded multilayer zirconia for CAD/CAM workflows.
Its key advantage lies in the balance between translucency, mechanical strength and material homogeneity, allowing the production of full-arch bridge restorations.
Dental zirconia: applications and value for the laboratory
Multilayer zirconia for dental laboratories has become one of the key materials used in CAD/CAM fixed prosthetics. It is appreciated for its biocompatibility, high mechanical strength, long-term stability and ability to produce reliable monolithic restorations.
In its pre-shaded multilayer version, it provides a more natural transition of shade and translucency while maintaining a structure suitable for demanding mechanical indications.
For the laboratory, the benefits are clear: higher productivity, monolithic esthetics, reduced layering procedures and reliable milling behavior.
Controlled strength
A mechanical performance level suitable for single-unit restorations, bridges and extended restorations when the workflow is properly controlled.
Multilayer esthetics
Shade and translucency gradients provide a more natural monolithic appearance with reduced need for extensive staining.
A key advantage: the ability to produce full-arch bridges
Many multilayer zirconias are promoted for their esthetic properties but remain mechanically too limited for long-span restorations.
With AUDENTAL 3D PRO, the material is designed to go further and may be used for the fabrication of full-arch bridges when the production protocol is properly controlled.
This advantage is directly related to the material quality, disc density, manufacturing consistency and the use of isostatic pressing technology.
Why isostatic pressing is superior
With isostatic pressing, pressure is applied uniformly in all directions. This results in a more homogeneous density throughout the entire disc.
For the dental laboratory, this translates into more consistent milling behavior, improved post-sintering stability and enhanced reliability for large restorations.
Why this technology is more expensive
Isostatic pressing requires more advanced industrial equipment and stricter quality control procedures.
In return, the laboratory benefits from a more consistent, homogeneous and reliable material for demanding restorative cases.
Pre-sintered zirconia milling and inspection
Pre-sintered zirconia should be processed in a suitable environment with efficient extraction, proper lighting and regular visual inspection.
It is recommended to inspect connectors, cervical areas and thin sections under magnification in order to detect micro-chipping or milling defects before sintering.
Characterization and finishing
Even in a pre-shaded version, zirconia can be customized using stains, coloring liquids or glazes adapted to the laboratory protocol.
This approach maintains the productivity benefits of multilayer zirconia while allowing additional esthetic personalization when clinically required.

Recommended sintering curve
Strict compliance with the sintering curve is essential to obtain the expected final density, dimensional stability and mechanical performance of the AUDENTAL 3D PRO disc.
A temperature rise that is too fast, hold stages that are not respected 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 down to room temperature |
This curve must always be validated according to the recommendations of the sintering furnace manufacturer, the load, the geometry of the restorations and the internal laboratory protocol.
Important sintering recommendations
- Follow the sintering furnace manufacturer’s recommendations.
- Use trays suitable for zirconia sintering.
- Prefer medium zirconia beads, approximately 1.6 to 2 mm.
- Use approximately 2 mm of beads in the tray.
- Keep restorations sufficiently spaced to ensure homogeneous heat distribution.
Proper furnace loading directly contributes to dimensional stability, surface integrity and the reliability of the final restoration.
CE certification and professional safety
The Audental brand benefits from genuine CE marking, an important point for materials intended for demanding prosthetic restorations.
This compliance should not be seen only as an administrative argument. It also reflects the level of material control, manufacturing consistency and industrial process quality.
For the laboratory, working with a CE-certified material provides additional security in terms of professional responsibility.

Technical FAQ & laboratory advice
How can cracks or chipping after sintering be avoided?
Strict compliance with the sintering curve is essential. A temperature rise that is too fast or abrupt cooling can create internal stress.
It is recommended to use 1.6 to 2 mm zirconia beads, with an approximate height of 2 mm in the tray, and to keep restorations properly spaced.
What working conditions are recommended for pre-sintered zirconia?
Pre-sintered zirconia should be processed in a box with dust extraction in order to limit fine particles.
Good lighting and inspection under magnification help detect milling defects before sintering.
Can the shade be customized after milling?
Yes, zirconia can be customized using suitable stains, coloring liquids or glaze systems.
This step makes it possible to adjust saturation, cervical effects and incisal areas according to the laboratory protocol.
Why use specific zirconia beads for sintering?
Zirconia beads provide stable and homogeneous support during the sintering cycle.
Beads that are too fine may become lodged in prosthetic areas and affect the final precision.
What are the best practices for an optimal esthetic result?
Use burs suitable for pre-sintered zirconia, clean the restoration carefully and follow the drying cycles if coloring liquids are applied.
After sintering, adjustments should be carried out with appropriate instruments and checked under neutral lighting.
