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*

Onlays, ¾ crowns, crowns
Telescope crowns, conus crowns
Bridges
Wide-span bridges
Cast posts / cores, bars, attachments
Implant-supported superstructures
Partial dentures
