Harmony PF
Harmony PF is a high gold, palladium-free casting alloy. The well-balanced composition of this alloy means a wide range of indications can be produced and veneered with the laboratory composite SR Nexco®.
Indications*
- Inlays
- Onlays, 3/4 crowns, crowns
- Telescope crowns, conus crowns
- Bridges
- Wide-span bridges
- Cast posts / cores, bars, attachments
- Implant-supported superstructures
- Partial dentures
