Porta Geo Ti
Porta Geo Ti is a palladium-free ceramic alloy. The high heat resistance allows for the production of ceramic veneered to metal bridges and implant-supported superstructures of high accuracy.
Indications*
- Inlays
- Onlays, ¾ crowns, crowns
- Telescope crowns, conus crowns
- Bridges
- Wide-span bridges
- Cast posts / cores, bars, attachments
- Implant-supported superstructures
- Partial dentures
