AUDENTAL 3D PRO 18 mm multilayer zirconia disc for dental laboratory
Référence: AUD018A1
AUDENTAL 3D PRO 18 mm multilayer zirconia disc - CE
The AUDENTAL 3D PRO 18 mm zirconia disc is designed for dental laboratories seeking a reliable, aesthetic and versatile pre-shaded multilayer zirconia for daily CAD/CAM workflows.
This 18 mm thickness provides additional material height for larger restorations while maintaining the required balance between translucency, mechanical strength and material homogeneity.
18 mm dental zirconia: applications and laboratory benefits
Multilayer zirconia for dental laboratories has become a key material in CAD/CAM fixed prosthetics. It enables the production of reliable monolithic restorations with excellent stability and a more natural appearance than conventional monochromatic zirconia.
In this 18 mm version, the AUDENTAL 3D PRO disc is particularly suitable for laboratories requiring comfortable material height for nesting, bridges and more demanding restorations.
For the laboratory, the objective is clear: improve productivity, maintain consistent monolithic aesthetics and reduce layering steps while preserving reliable milling behavior.
Strength suitable for extended restorations
The material provides mechanical performance suitable for single units, bridges and more extensive restorations, when the prosthetic design and sintering protocol are properly validated.
Natural multilayer aesthetics
The progressive transition of shade and translucency helps achieve a more natural monolithic result, with less systematic staining required on standard cases.
A key advantage: full-arch bridges can be produced with an 18 mm disc height
Many multilayer zirconias are promoted for their aesthetics, but remain mechanically limited when restorations become more extensive or larger in volume.
With AUDENTAL 3D PRO 18 mm, the material is designed to go further: this version provides additional height for the laboratory while maintaining a structure compatible with the fabrication of full-arch bridges, when the production protocol is properly controlled.
This capability is based on the quality of the material, density homogeneity, post-sintering stability and the use of true isostatic pressing.
Why isostatic pressing is superior
With isostatic pressing, pressure is applied uniformly in all directions. This method promotes a more consistent density throughout the entire disc.
For the laboratory, this results in more consistent milling, better stability after sintering and increased reliability on extended restorations.
Why this manufacturing process is more demanding
Isostatic pressing requires more advanced industrial equipment and stricter quality control than simpler compaction methods.
In return, the laboratory benefits from a more homogeneous, more stable material, better suited to technical restorations with high mechanical requirements.
Milling and inspection of pre-sintered zirconia
Pre-sintered zirconia should be processed in a clean environment, with efficient suction, proper lighting and regular visual inspection.
It is recommended to inspect connectors, cervical areas and thin sections under magnification to detect micro-chipping or milling defects before sintering.
Characterization and finishing
Although pre-shaded, AUDENTAL 3D PRO zirconia can be customized with stains, coloring liquids or glazes adapted to the laboratory protocol.
This approach preserves the productivity of multilayer zirconia while adding aesthetic customization when the clinical case requires it.

Recommended sintering curve
Strict compliance with the sintering curve is essential to obtain the final density, dimensional stability and mechanical performance expected from the AUDENTAL 3D PRO 18 mm disc.
Heating too quickly, incorrect holding times or poorly controlled cooling can 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 should always be validated according to the recommendations of the sintering furnace manufacturer, the load, the geometry of the restorations and the laboratory’s internal protocol.
Important sintering recommendations
- Follow the recommendations of the sintering furnace manufacturer.
- Use sintering trays suitable for zirconia.
- Prefer medium zirconia beads, approximately 1.6 to 2 mm.
- Use approximately 2 mm of beads in the sintering tray.
- Leave enough space between restorations to ensure homogeneous heat diffusion.
Correct furnace loading directly contributes to dimensional stability, surface integrity and the reliability of the final result.
CE certification and professional safety
The Audental brand benefits from genuine CE marking, an important point for materials intended for demanding prosthetic restorations.
This conformity 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 recommendations
How can cracks or chips after sintering be avoided?
Strict compliance with the sintering curve is essential. Heating too quickly or cooling too abruptly may create internal stress.
It is recommended to use zirconia beads of 1.6 to 2 mm, with a height of approximately 2 mm in the tray, and to space restorations properly.
Why choose 18 mm thickness instead of 16 mm?
The 18 mm thickness provides additional height for certain prosthetic cases, especially when the laboratory needs more nesting margin within the disc.
It can be useful for posterior restorations, certain bridges or morphologies requiring more available volume before milling.
What working conditions are recommended for pre-sintered zirconia?
Pre-sintered zirconia should be processed in an enclosure with suction to limit fine dust exposure.
Good lighting and inspection under magnification help detect milling defects before sintering.
Can the shade be customized after milling?
Yes, zirconia can be customized with suitable stains, coloring liquids or glaze materials.
This step makes it possible to adjust saturation, cervical effects and incisal areas according to the laboratory protocol.
Why use specific beads for zirconia sintering?
Zirconia beads provide stable and homogeneous support during sintering.
Beads that are too fine may become trapped in certain prosthetic areas and affect the final precision.
What are the best practices for optimal aesthetic results?
Use burs suitable for pre-sintered zirconia, clean the restoration carefully and respect drying cycles if coloring liquids are applied.
After sintering, adjustments should be performed with appropriate instruments and checked under neutral lighting.
