PMMA for digital denture bases
DD base P HI are gingiva-colored blanks based on impact- modified polymethyl methacrylate and suitable for the manufacture of digital prosthesis bases. With the CAD/CAM process, you achieve reproducible milling results with a precise fit and minimal post-processing effort..
Benefits:
- Biocompatible
- High stability through high impact modification
- Very good polishing properties
- Very good bond to denture teeth and cold-curing polymers (PMMA)
- Available in four colors
