Zirconia-Based

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

Benefits

• Zirconia frameworks exhibit excellent long-term stability
• Monolithic zirconia is 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-based restorations with adequate retention do not need resin bonding. Zirconia-based 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 silica coating eg. CoJet™ or Rocatec™
• Ceramics employed are issued with US IdentCeram^_® certificates to verify the American Dental Association classification and content of the restorative materials
