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
