3M™ ESPE™ Lava™ Crowns & Bridges are touted as one of the most esthetic and clinically proven all-ceramic restorations available today. Lava restorations offer excellent long-term stability with no allergenic potential. Milled from a presintered Lava zirconia block, each framework is colored using one of eight VITA® shades. After sintering for 10 hours to gain strength and fracture resistance, the framework is layered with feldspathic Lava Ceram porcelain. The final Lava restoration demonstrates exceptional marginal fit, lifelike translucency and long-term durability.
