Maxigold

Au (59.5%)-based dental casting alloy, Type 4

Maxigold

Maxigold is a gold-reduced casting alloy with a wide range of indications. It is easy to process and its golden yellow colour allows natural shade effects in the restoration veneered with laboratory composite SR Nexco.

Indications*

  • Inlays
  • Onlays, ¾ crowns, crowns
  • Telescope crowns, conus crowns
  • Bridges
  • Wide-span bridges
  • Cast posts / cores, bars, attachments
  • Implant-supported superstructures
  • Partial dentures
