Porta Reflex

Porta Reflex is a silver-free, high gold ceramic alloy. The mechanical properties allow a wide range of indications and the golden yellow colour enhances the natural shade reproduction in the veneer.

Indications*

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