Portadur P2

Au (71.0%)-based dental casting alloy, Type 4

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.

  • Onlays, 3/4 crowns, crowns
  • Telescope crowns, conus crowns
  • Bridges
  • Wide-span bridges
  • Cast posts / cores, bars, attachments
  • Implant-supported superstructures
  • Partial dentures
