I have been working with B&D Dental Technologies for the past few years now and am lucky enough to have been the first lab to use their Beyond Zirconia. It has better aesthetics than Emax and twice as strong. Using their Beyond coloring liquid my shades comes out perfect! All my Emax Dr. switched to full contour Beyond and love it.
