Zirconia-Based Restorations

Zirconia based restorations are perfect for a wide range of crown and bridge applications. Fully Monolithic zirconia (FMZ) is also available in the Origin range.

Zirconia - strong, accurate and stable

Zirconia-based restorations are perfect for a wide range of crown and bridge applications, including anterior and most posterior requirements. Zirconia ceramics are used for fixed restorations as a framework due to their mechanical and optical properties.

Benefits for your patients

  • Zirconia frameworks are excellent for long-term stability.
  • Monolithic zirconia crown compositions are strong, accurate and resistant to fracture and crack propagation.

Considerations

  • PFZ should be avoided in bruxers or patients with parafunctional activities.
  • Care with case selection for extensive implant-borne zirconia frameworks.
  • Full coverage zirconia restorations with adequate retention don’t need resin bonding. Zirconia crowns and bridges with good retention can be cemented with resin-modified glass ionomer.
  • If retention is compromised, a resin cement – with prior application of a separate self-etching bonding agent – is suggested, or a silica coating such as CoJet™ or Rocatec™.
  • Ceramics employed are issued with US IdentCeram® certificates to verify the American Dental Association classification and content of the restorative materials.
