W-5
W-5 is a classical, reduced-gold ceramic alloy. The good casting characteristics and the high heat resistance allow for the production ceramic veneered to metal frameworks and implant-supported superstructures of high accuracy.
Indications*
- Inlays
- Onlays, ¾ crowns, crowns
- Telescope crowns, conus crowns
- Bridges
- Wide-span bridges
- Cast posts / cores, bars, attachments
- Implant-supported superstructures
- Partial dentures
