AUDENTAL 3D PRO 20 mm zirconia disc for full-arch CAD/CAM bridges and long-span restorations
The AUDENTAL 3D PRO 20 mm zirconia disc is a pre-shaded multilayer zirconia blank designed for dental laboratories producing full-arch bridges, long-span restorations and CAD/CAM cases requiring significant vertical material height.
Its 20 mm thickness provides comfortable vertical clearance for large restorations, high posterior morphologies and extended prosthetic frameworks, while preserving the benefits of multilayer zirconia: progressive aesthetics, post-sintering stability and mechanical strength suitable for demanding laboratory work.

A 20 mm zirconia blank designed for full-arch bridges
Fabricating a full-arch zirconia bridge involves greater technical constraints than producing a single crown or a short-span bridge. Restoration length, material mass, connector cross-section and dimensional stability after sintering become essential parameters for the dental laboratory.
The 20 mm format provides a more comfortable blank height for nesting long-span restorations. This additional material reserve helps position prosthetic elements more effectively, anticipate larger prosthetic volumes and reduce compromises during CAD/CAM design.
For the dental technician, this thickness is particularly relevant for full-arch bridges, long frameworks, bulky posterior restorations and cases requiring greater vertical clearance before milling.
20 mm height for greater nesting freedom
For a full-arch bridge or a long-span restoration, placement within the zirconia disc must take into account restoration height, multilayer gradient orientation and connector position.
The 20 mm thickness provides additional freedom when organising restorations in the CAD/CAM nesting software and helps secure the design before milling.
- More comfortable positioning of long-span restorations.
- Easier management of large prosthetic volumes.
- Improved control of multilayer gradient orientation.
- Material reserve suitable for high morphologies.
Multilayer gradient for monolithic bridges
The multilayer structure of AUDENTAL 3D PRO zirconia provides a progressive transition between cervical, dentine and incisal zones.
This gradient helps achieve a more natural appearance on long monolithic restorations, where aesthetic integration must remain consistent across the entire arch.
- Pre-shaded zirconia for improved shade consistency.
- Progressive chromatic transition.
- Suitable for monolithic restorations.
- Customisation possible after sintering.
Professional applications of the AUDENTAL 3D PRO 20 mm zirconia disc
The 20 mm version of the AUDENTAL 3D PRO disc is particularly suitable for laboratories seeking to secure long-span cases without changing zirconia material family.
- Full-arch bridges: material height adapted to long and voluminous restorations.
- Monolithic restorations: multilayer gradient for a progressive aesthetic result.
- Crowns and bridges: suitable for single-unit or multi-unit restorations according to the laboratory protocol.
- Posterior restorations: useful material reserve for high morphologies and mechanically stressed areas.
- CAD/CAM production: Ø 98.4 mm format compatible with standard open milling machines.
Isostatic pressing for consistent density
Isostatic pressing applies uniform pressure to the material. This process promotes consistent density throughout the disc, including in a significant 20 mm thickness.
This homogeneity is essential for consistent milling behaviour, reliable stability after sintering and improved predictability on long-span restorations.
Manufacturing adapted to full-arch bridges
A full-arch bridge requires a stable, consistent and traceable material. The manufacturing process must limit internal variations that could influence shrinkage, final density or mechanical behaviour.
Isostatic pressing, combined with strict quality control, enables the laboratory to work with a more reliable zirconia for large and mechanically demanding restorations.
Essential checks before sintering
Before sintering, the laboratory must carefully check connectors, embrasures, cervical areas, thin margins and support surfaces. An undetected defect on a long-span restoration can weaken the entire framework after sintering.
Efficient dust extraction, suitable milling burs and visual inspection under magnification are recommended to secure production. On a full-arch bridge, every transition area should be checked before placing the restoration in the furnace.
Before milling
- Check positioning within the disc.
- Verify connector cross-sections.
- Respect minimum wall thicknesses.
- Select a CAD/CAM strategy adapted to the restoration.
Before sintering
- Inspect embrasures and thin areas.
- Remove milling residues.
- Check supports and extensions.
- Follow the laboratory sintering protocol.

Sintering curve: a critical parameter for full-arch zirconia bridges
When fabricating a full-arch zirconia bridge, strict compliance with the sintering curve becomes a critical parameter. Temperature variation, excessively rapid cooling or insufficient holding time can generate internal stress and compromise the final stability of the restoration.
The combination of a CE-certified material, homogeneous isostatic pressing and strict adherence to the sintering cycle contributes to a more predictable, stable and long-lasting restoration.
| Initial heating rate | 10 °C/min up to 900 °C |
|---|---|
| First holding stage | 900 °C for 30 min |
| Intermediate heating rate | 3 °C/min up to 1300 °C |
| Second holding stage | 1300 °C for 10 min |
| Final heating rate | 3 °C/min up to 1500 °C |
| Main holding stage | 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 sintering furnace manufacturer’s recommendations, the furnace load, the geometry of the restorations and the laboratory’s internal protocol.

FAQ – AUDENTAL 3D PRO 20 mm zirconia disc
Why choose a 20 mm zirconia disc for a full-arch bridge?
The 20 mm disc offers a more comfortable material height for positioning a full-arch bridge in the CAD/CAM software.
This additional height helps manage long restorations, high morphologies and larger connectors, while maintaining the aesthetic and mechanical properties of AUDENTAL 3D PRO zirconia.
Is CE marking important for full-arch zirconia bridges?
Yes. CE marking is particularly important when a laboratory produces a full-arch bridge. A long-span restoration involves more material, greater mechanical constraints and higher stability requirements than a single crown.
A CE-certified zirconia provides additional security in terms of compliance, traceability and material selection, provided that technical indications, CAD/CAM parameters and the sintering cycle are respected.
What are the risks if the sintering curve is not respected?
Heating too quickly, using insufficient holding time or cooling too abruptly may create internal stress within the zirconia.
On a full-arch bridge, these stresses may lead to distortion, cracks, chipping or loss of dimensional stability. Respecting the sintering curve is therefore essential.
Why is isostatic pressing important?
Isostatic pressing promotes homogeneous density throughout the disc. On a long-span restoration, this regularity is important to limit behavioural variations during milling and sintering.
For a full-arch bridge, material homogeneity contributes to dimensional stability, shrinkage consistency and the mechanical reliability of the final framework.
Can 20 mm zirconia be aesthetically customised?
Yes. AUDENTAL 3D PRO 20 mm zirconia can be customised with colouring liquids, stains or glazes compatible with the laboratory protocol.
On a full-arch bridge, this customisation helps improve cervical effects, incisal nuances and the overall aesthetic integration of the restoration.
