W
W is a reduced-gold ceramic alloy, suitable for conventional metal-ceramics. The good flow characteristics during casting and the high strength allow for a wide range of indications.
Indications*
- Inlays
- Onlays, ¾ crowns, crowns
- Telescope crowns, conus crowns
- Bridges
- Wide-span bridges
- Cast posts / cores, bars, attachments
- Partial dentures
