PC Essence™ is a state of the art 2-phase glass ceramic containing leucite crystals offering 180-360 degree pressed ceramic margins. Pressing porcelain on a modified alloy frame combines the strength of PFM with the aesthetics of an all ceramic restoration. Unlike any other system, PC Essence allows for combination cases utilizing the Vita shade system. The natural blue flourescence allows for a perfect match to the surrounding dentition, while the smooth ceramic is kind to natural enamel and gingival tissue.
