Portadur P2
Portadur P2 is a high gold, palladium-free casting alloy with a warm golden colour. The mechanical and physical properties of this alloy allow the production of even long-span restorations.
Indications*
- Inlays
- Onlays, 3/4 crowns, crowns
- Telescope crowns, conus crowns
- Bridges
- Wide-span bridges
- Cast posts / cores, bars, attachments
- Implant-supported superstructures
- Partial dentures
