d.SIGN 98
d.SIGN 98 is a high gold, palladium-free ceramic alloy. The mechanical properties allow for a wide range of indications and the golden yellow colour enhances the natural shade reproduction in the veneer.
Indications*
- Telescope crowns, conus crowns
- Bridges
- Wide-span bridges
- Cast posts / cores, bars, attachments
- Implant-supported superstructures
- Partial dentures
