CAD CAM pmma disc 98mm dental PMMA blank

 

 

CAD/CAM PMMA Disc (Ø98 mm Dental PMMA Blank) is  for the fabrication of temporary dental restorations such as crowns, bridges, inlays, onlays, and veneers using CAD/CAM milling systems.

The material is based on high-purity polymethyl methacrylate (PMMA), processed under controlled polymerization conditions to ensure stable internal structure, consistent density, and reliable machining performance.

 

Available Specifications

Processing Performance

The disc is optimized for CAD/CAM milling systems and shows stable cutting behavior during machining:

No tool sticking during high-speed milling

Clean edge formation with minimal burrs

Low internal stress reduces risk of deformation or cracking

Stable dimensional accuracy during and after processing

Anti-static surface reduces dust adhesion during handling

 

 

Compatibility

Fully compatible with mainstream open CAD/CAM systems, including:
Wieland, VHF, Roland, Imes-Icore, Zirkonzahn, Amann Girrbach, and other standard dental milling platforms.

Applications

Suitable for a wide range of temporary and diagnostic restorations:

Temporary crowns and bridges

Inlays and onlays

Veneers

Full-contour provisional restorations

Wax-up and model alternatives in digital workflows
