PMMA for digital denture bases
DD base P HI are colored milling blanks based on the raw material of our proven DD Bio Splint P HI. The material is ideally suited for the production of digital denture bases and indicated for the long-term use in the oral cavity.
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
