Zirconia characteristics

Zirconia, or Zirconium dioxide, is a white esthetic material, with a great biocompatibility, in-vitro and in-vivo. Yttria stabilised zirconia (ZrO2/Y2O3 = TZP) has a grain size <1µm, a density of 6.08g/cm3 and a hardness of 1400Hv. Other main characteristics of Zirconia ceramics:

• A high mechanical strength, fracture toughness, and a good wear resistance (Zirconia has a higher mechanical strength than other ceramics used for medical applications).
• A good resistance to corrosion and to chemicals.
• Natural esthetic translucency

Zirconia ceramics’ main applications

Thanks to its excellent properties, Zirconia is used for:

• Zirconia ceramics dental implants : abutments, posts, screws…
• Blanks for dental restorations such as crowns, bridges, inlays and onlays, milled on CAD/CAM systems
• Zirconia knives, scissors and tools.
• Electroceramics
• Orthopaedic implants (hip and other medical implants)
• Oxygen sensors
• Zirconia part for watches and jewelry
• Fiber optical connectors
• Zirconia ceramics components for endoscopy
