The new full-contour zirconia system offers an efficient and reliable method for producing full-contour restorations and consists of preshaded zirconia discs, stain pastes, modifier pastes and leucite-containing glaze. Using the five pre-shaded zirconia discs and set of eight stain pastes, you can achieve any of the 16 Vita A-D shades as well as Bleach shades; no dipping or use of coloring liquids is required at any point in the process. Mooki Kim, CDT, describes how this system compares to other systems and gives detailed instructions for shading a milled full-contour zirconia crown to its desired final shade using a traditional stain and glaze technique.
