Porta Geo Ti

Au (77.4%)-based dental metal-ceramic alloy, Type 4

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
