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
