Full Contour Zirconia is a crown made to full contour of solid zirconia. Although much less esthetic than e.max, it is far stronger (800-900mpa) and therefore well suited to withstand severe parafunctional activity. With these virtually unbreakable crowns, you can offer your patients the strength to withstand severe bruxing and avoid metal restorations. These crowns can only be made by CAD/CAM. They are milled from a block of “green” zirconia, infiltrated with a special coloring liquid and then sintered at 1500 C in a special oven. They are then customized with paint-on shades, polished, and then covered with a layer of glaze for a final shine.
