The Strongest All-Ceramic Restoration Available
Finally, the strength you’ve been looking for in an esthetic metal-free restoration is possible with Lava, the zirconia-based all-ceramic system by 3M™ ESPE™. The Lava system combines CAD/CAM technology with an extraordinarily translucent zirconia framework that can be custom colored creating a restoration strong enough for long span bridges, with outstanding fit and biocompatibility and the aesthetics your patients have come to expect. Now you can have it all!
