d.SIGN 30
d.SIGN 30 is a cobalt-chromium ceramic alloy. The excellent melting and flow properties enable easy divesting and allow accurately fitting restorations to be made.
Indications*
- Telescope crowns, conus crowns
- Bridges
- Wide-span bridges
- Cast posts / cores, bars, attachments
- Implant-supported superstructures
- Partial dentures
