  • Applications: PFZ substructures , crowns, copings, long span bridges
  • High flexural strength and low translucency
  • Opaqueness covers abutments perfectly

High Strength (HS) zirconia has optimal milling properties and is recom- mended for porcelain fused to zirconia framework restorations. The material accepts porcelain layering exceptionally well and its low trans- lucency perfectly covers abutments. It comes with an extremely high flexural strength (close to 1500 MPa) and higher fracture toughness for long span bridges and difficult jobs where additional strength is required
