Purchase Online Today

Evolution Lite is a reduced-gold ceramic alloy, suitable for conventional metal-ceramics. The higher strength imparts this alloy with a high marginal strength, in particular during multiple firing, and allows accurately fitting restorations to be produced.

Indications*

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