PMMA Monolayer Disc 98 × 20 mm CAD/CAM – DLG
PMMA Monolayer Disc 98 × 20 mm – CAD/CAM Provisional Resin
PMMA disc designed for high-volume provisional restorations in
CAD/CAM dental laboratories.
Ø 98.5 mm format compatible with open milling systems.
Why choose the 20 mm version?
The 20 mm thickness is intended for cases requiring a
higher material reserve: increased prosthetic height, large volumes,
short to medium provisional bridges.
It provides enhanced mechanical safety while maintaining
stable milling and shade consistency typical of monolayer PMMA.
- Best use: large provisional restorations.
- CAD/CAM benefit: stable milling on thicker areas.
- Lab tip: pick 20 mm when 16/18 mm becomes limiting in height.
Key benefits in the lab
This CAD/CAM PMMA disc 98 × 20 mm supports reliable production in
dental laboratories, with controlled finishing and easy polishing.
Dental indications
- High-volume provisional crowns.
- Short to medium provisional bridges.
- Transitional restorations requiring a reinforced structure.
20 mm specific: recommended when the restoration requires increased prosthetic height.
Lab workflow
- Mount the Ø 98.5 mm disc in a compatible holder.
- Select the PMMA program adapted to 20 mm thickness.
- Mill the provisional restoration following your CAD/CAM workflow.
- Trim, adjust and polish for a homogeneous finish.
Lab tip: on thicker areas, well-maintained tools improve finish and precision.

Frequently asked questions
What is the difference between 18 mm and 20 mm?
The 20 mm disc provides a higher material reserve than 18 mm.
It is recommended for large provisional restorations.
It adds extra mechanical safety for lab production.
Is this disc suitable for provisional bridges?
Yes, it is suitable for short to medium provisional bridges.
Its thickness improves the overall stability of the restoration.
Is milling time longer with 20 mm?
Milling may be slightly longer than with thinner discs.
In return, you get higher material reserve and safety.
Which CAD/CAM mills is it compatible with?
It is compatible with open milling systems that accept Ø 98.5 mm discs.
It integrates into standard CAD/CAM workflows in dental labs.
