18 mm dental zirconia for CAD/CAM prosthetic production
Multilayer zirconia for dental laboratories has become a key material in fixed CAD/CAM prosthetics. It allows technicians to produce stable monolithic restorations with 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 prosthetic designs.
The objective for the laboratory is clear: improve productivity, maintain consistent monolithic aesthetics and reduce systematic layering steps while preserving reliable milling behaviour.
Strength suitable for extended restorations
AUDENTAL 3D PRO provides mechanical performance suitable for single units, bridges and more extensive restorations, when the prosthetic design, connector dimensions and sintering protocol are properly validated.
The 18 mm height offers additional nesting flexibility for laboratories producing posterior restorations, multi-unit bridges and larger anatomical morphologies.
Natural multilayer aesthetics
The progressive transition of shade and translucency helps obtain a more natural monolithic result, with less systematic staining required on standard clinical cases.
This multilayer structure supports a more efficient workflow for laboratories seeking a balance between aesthetics, repeatability and production speed.
A key advantage: full-arch bridges with an 18 mm disc height
Many multilayer zirconias are mainly selected for their aesthetics, but can become more technically demanding when restorations are larger, more voluminous or mechanically more complex.
With AUDENTAL 3D PRO 18 mm, the laboratory benefits from additional material height while keeping a zirconia structure compatible with the production of full-arch bridges, provided that the design, milling strategy and sintering protocol are properly controlled.
This capability relies on material quality, density homogeneity, post-sintering stability and the use of true isostatic pressing.
Why isostatic pressing matters
With isostatic pressing, pressure is applied uniformly in all directions. This manufacturing method promotes more consistent density throughout the entire zirconia disc.
For the laboratory, this supports more regular milling behaviour, improved stability after sintering and increased reliability for extended restorations.
A more demanding manufacturing process
Isostatic pressing requires more advanced industrial equipment and stricter quality control than simpler compaction methods.
In return, the dental laboratory benefits from a more homogeneous and 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 CAD/CAM environment, with efficient suction, 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.
Characterisation and finishing
Although pre-shaded, AUDENTAL 3D PRO zirconia can be customised with stains, colouring liquids or glazes adapted to the laboratory protocol.
This approach preserves the productivity of multilayer zirconia while allowing aesthetic customisation when the clinical case requires it.

Recommended sintering curve for AUDENTAL 3D PRO 18 mm zirconia
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.
A heating rate that is too fast, holding stages that are not respected 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 1500 °C |
| Main hold | 1500 °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 furnace 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.
- Inspect the restorations before sintering, especially connectors, margins and thin areas.
Correct furnace loading directly contributes to dimensional stability, surface integrity and the reliability of the final prosthetic 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 considered only as an administrative requirement. It also reflects material control, manufacturing consistency and industrial process quality.
For the dental laboratory, working with a CE-certified material provides additional security in terms of professional responsibility and traceability.

FAQ – AUDENTAL 3D PRO 18 mm zirconia disc
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 within the zirconia structure.
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 during the sintering cycle.
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 a clean milling environment with efficient suction in order to limit fine dust exposure.
Good lighting and inspection under magnification help detect milling defects before sintering, particularly on connectors, margins and thin anatomical areas.
Can the shade be customised after milling?
Yes, zirconia can be customised with suitable stains, colouring liquids or glaze materials, according to the laboratory protocol.
This step makes it possible to adjust saturation, cervical effects and incisal areas while preserving the productivity of a multilayer zirconia workflow.
Why use specific beads for zirconia sintering?
Zirconia beads provide stable and homogeneous support during sintering, helping to preserve the shape and stability of the restoration.
Beads that are too fine may become trapped in certain prosthetic areas and affect the final precision of the restoration.
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 colouring liquids are applied.
After sintering, adjustments should be performed with appropriate instruments and checked under neutral lighting before final glazing or polishing.
