This week at the California Dental Association spring meeting, 3M ESPE introduced Lava Plus high translucency zirconia, a CAD/CAM system designed to deliver the aesthetics of a layered restoration from an all-zirconia block.
Lava Plus all-zirconia material provides strength and resists chipping, and with its patented shading technology, enables aesthetic all-zirconia or traditionally layered restorations, according to 3M ESPE.
The zirconia block comes in 18 colors and eight Lava Plus Effect shades and matches the Vita Classical A1-D4 shades, including the bleached shades, as well as features direct conversion to the most common Vita System 3D Master shades, 3M ESPE said.
In addition, the zirconia block can be milled with 0.3-mm minimum wall thickness for anterior single unit restorations and 0.5-mm minimum wall thickness for posterior restorations. It requires three times less occlusal preparation than lithium disilicate glass ceramic, according to 3M ESPE internal studies.
Lava Plus zirconia restorations can be cemented using either an adhesive resin dental cement or a self-adhesive resin dental cement, the company noted.
