4Design Multilayer Permanent PMMA Disc for CAD/CAM Milling
PMMA disc for the CAD/CAM milling of permanent artificial teeth for removable or fixed dental prostheses. The multilayer structure and high translucency promote a natural aesthetic result after milling, with stable colors and high wear resistance.
Features
- Multilayer structure with a natural color transition and uniform aesthetics.
- High translucency for a more vibrant and realistic finish after milling.
- Wear and abrasion resistance and hardness suitable for prolonged use.
- Color stability over time.
Available Colors and Thicknesses
- Colors: A1, A2, A3, A3.5, B1, C2, BL1 and BL2.
- Thicknesses: 14, 16 and 20 mm.
- Diameter: 98.5 mm.
Composition
Acrylic copolymer based on PMMA (>99%), inert mineral pigments and other non-toxic substances (<1%).
Compatibility and CAD/CAM Processing
- Compatible with open CAD/CAM milling systems with a 98.5 mm disc and, depending on the system, other formats based on measurements and contours.
- Processing with tungsten carbide burs is recommended.
- Consider the orientation of the incisal layer to take advantage of the multilayer effect.
Finishing and Polishing
Polish without excessive pressure and at low speeds to avoid overheating. Resin polishing brushes and pastes help optimize shine and aesthetics and reduce plaque retention.
Recommended minimum thickness: >2.5 mm.
Bonding and Maintenance
- For bonding, use adhesives compatible with PMMA following the manufacturer's instructions.
- Cleaning and disinfection should preferably be carried out at low temperatures, avoiding high temperatures and aggressive chemicals not recommended for PMMA.
Packaging
1 disc.
