Lava™ System from 3M ESPE

 

 

The Lava™ All-Ceramic System from 3M ESPE encompasses a CAD/CAM procedure for the creation of all-ceramic crowns and bridges for anterior and posterior applications. The framework ceramic consists of zirconia with a specially designed overlying veneer ceramic. The frameworks are made using CAD/CAM procedures (scanning, computer-aided framework design and milling) from pre-sintered zirconia blanks. The system produces high-strength restorations with excellent fit. The size of the final restoration has been increased to compensate for shrinkage during sintering.

Benefits

  • Biocompatible
  • Excellent long-term aesthetics
  • Due to the low thermal conductivity of the ceramic, there is no sensitivity to temperature variation

Considerations

  • Traditional cementation with 3M ESPE Ketac™ Cem or RelyX™ Luting Cement is recommended for cementing crowns and bridges made from Lava™ system materials for every restoration type
  • Ceramics employed are issued with US IdentCeram® certificates to verify the American Dental Association classification and content of the restorative materials
