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
