The 3M ESPE Lava system is an innovative CAD/CAM technology that uses a zirconium oxide base for all-ceramic crowns and bridges. The esthetics of Lava restorations, coupled with talented technicians, represent one of the optimums in all-ceramic systems. Boasting a flexural strength similar to traditional PFMs, 3M Lava restorations are some of the strongest, most esthetic restorations available today.
