PMMA multilayer for aesthetic long-term provisionals and prosthetic teeth
DD poly Y ML are pre-colored, multi-layer CAD/CAM milling blanks based on polymethyl methacrylate (PMMA). The material impresses with harmoniously graduated color nuances in five layers, which create a natural color gradient and thus guarantee a lifelike appearance. DD poly Y ML can be combined with DD base P HI to achieve a precise digital prosthetic solution with optimal aesthetics and functionality.
Advantages:
- Good bond to prosthetic base material
- Good polishing properties
- No porosities in the material
