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
