Why choose AUDENTAL 3D PRO multilayer zirconia in a dental laboratory?
Multilayer zirconia for dental laboratories is now one of the key materials used in digital fixed prosthodontics. It allows laboratories to produce strong, consistent and aesthetic restorations while reducing some of the time-consuming layering or characterisation steps.
As a pre-shaded multilayer zirconia, it provides a more natural transition between cervical, dentine and incisal zones. The laboratory obtains a more harmonious monolithic result, with improved shade management and controlled translucency.
For a CAD/CAM workflow, the benefits are clear: productivity, dimensional stability, usable aesthetics and reliable milling behaviour.
High mechanical strength for crowns, bridges and extended restorations
AUDENTAL 3D PRO offers a mechanical profile suitable for single-unit restorations, multi-unit bridges and extended restorations, provided that indications, connector dimensions, minimum wall thicknesses and the sintering curve are respected.
This strength level is particularly useful for laboratories looking for a versatile zirconia capable of covering a wide range of prosthetic cases.
It helps rationalise material selection while maintaining technical safety for routine CAD/CAM restorations and more extended prosthetic work.
Natural multilayer gradient for aesthetic monolithic restorations
The multilayer structure promotes a more natural appearance than monochromatic zirconia. The progressive transition of shade and translucency helps achieve a more lifelike restoration with less systematic staining.
This is useful for visible posterior crowns, monolithic bridges and restorations requiring a balance between production efficiency and aesthetic result.
The pre-shaded material helps the laboratory obtain a consistent chromatic base before finishing, staining, glazing or polishing.
Multilayer zirconia suitable for full-arch bridge fabrication
Many multilayer zirconias are promoted for their aesthetics, but may be mechanically limited for long-span or full-arch restorations.
With AUDENTAL 3D PRO, the material is designed to go further: it can be used for the fabrication of full-arch zirconia bridges, provided that design, connectors, milling and sintering are properly controlled.
This advantage is linked to material quality, disc density, manufacturing consistency and isostatic pressing.
What are the advantages of isostatic pressing for dental zirconia?
With isostatic pressing, pressure is applied uniformly in all directions. This method helps achieve a more homogeneous density throughout the disc.
For the dental laboratory, this results in more consistent milling, better stability after sintering and greater reliability for extended restorations.
This material homogeneity is important for highly stressed monolithic restorations and long-span bridges requiring strong internal consistency.
Why is isostatically pressed zirconia a higher-quality option?
Isostatic pressing requires more demanding industrial equipment and stricter quality control.
In return, the laboratory benefits from a more consistent, more homogeneous and more reliable material for technical restorations, particularly long-span bridges or highly stressed monolithic restorations.
This consistency contributes to the safety of the CAD/CAM protocol, from milling to final sintering.
Best practices for milling pre-sintered zirconia in CAD/CAM
Pre-sintered zirconia must be processed in a suitable environment, with efficient dust extraction, proper lighting and regular visual inspection.
It is advisable to inspect connectors, cervical areas, embrasures and thin sections under magnification in order to detect micro-chipping or milling defects before sintering.
Strict inspection before placing the restoration in the furnace reduces the risk of cracks, chipping or surface defects after sintering.
Shade customisation and aesthetic finishing of zirconia
Even when pre-shaded, zirconia can be customised with stains, colouring liquids or glazes compatible with the laboratory protocol.
This approach maintains the productivity of multilayer zirconia while adding aesthetic customisation when the clinical case requires it.
Final polishing and surface quality remain decisive for optical integration and long-term performance of the restoration.

Technical FAQ – AUDENTAL 3D PRO multilayer zirconia
Can the AUDENTAL 3D PRO zirconia disc be used for full-arch bridges?
Yes, the AUDENTAL 3D PRO disc can be used for the fabrication of full-arch zirconia bridges, provided that the design protocol, minimum wall thicknesses, connector sections and sintering curve are respected.
As with any extended restoration, success depends not only on material selection but also on CAD/CAM file quality, milling, pre-sintering inspection and compliance with the recommendations of the furnace used.
Why is isostatic pressing important for dental zirconia?
Isostatic pressing helps obtain a more homogeneous density throughout the disc. This homogeneity is important for reducing internal material variations and improving milling consistency.
For the laboratory, this brings better stability after sintering, more consistent precision and additional safety for long-span or technically demanding restorations.
How can cracks or chipping after zirconia sintering be avoided?
Cracks or chipping may be caused by milling defects, areas that are too thin, insufficient connectors, incorrect positioning in the tray or an unsuitable thermal cycle.
It is recommended to inspect restorations before sintering, use suitable zirconia beads, avoid overloading the tray and respect the temperature holding stages. Heating too quickly or cooling too abruptly may create internal stress in the restoration.
What working conditions are recommended for pre-sintered zirconia?
Pre-sintered zirconia should be processed in a clean environment with efficient suction to limit the fine dust produced during milling and adjustments.
Good lighting, inspection under magnification and the use of instruments suitable for zirconia help identify micro-chipping, marginal defects or weakened areas before sintering.
Can the shade be customised after milling?
Yes. Although AUDENTAL 3D PRO zirconia is pre-shaded and multilayered, it can be customised with colouring liquids, stains or glazes compatible with the laboratory protocol.
This customisation allows the technician to adjust cervical effects, saturation, incisal nuances or surface details. It is particularly useful when the clinical case requires more precise aesthetic integration.
Why use specific beads for zirconia sintering?
Zirconia sintering beads support the restorations during the thermal cycle and help provide a more homogeneous heat distribution in the tray.
Beads that are too fine may become trapped in certain prosthetic areas, while poor positioning may create stress or deformation. For this type of zirconia, medium beads of approximately 1.6 to 2 mm are recommended, with a controlled height in the tray.
What are the best practices for achieving an optimal aesthetic result?
To achieve a consistent aesthetic result, the disc orientation during nesting, shade selection, wall thickness control and careful management of visible areas must be respected.
After sintering, finishing should be carried out with instruments suitable for zirconia. Staining, glazing and final polishing then improve optical integration and surface quality.
