BioUniversal E is a copper-free, universal alloy, which can be used for a wide range of indications. Due to its low density, this alloy is suitable for the production of economical restorations and can be veneered with low-fusing special ceramics.
Indications*
- Onlays, 3/4 crowns, crowns
- Telescope crowns, conus crowns
- Bridges
- Wide-span bridges
- Cast posts / cores, bars, attachments
