Super translucent zirconia blocks
zirconia blocksare made of nanometer medical grade zirconia powder. The powder are firstly compacted by cold isostaticpressing with high compressive strength and then pre-sintered to a certain degree to offer good machinability.
ST zirconia blocks can be used to create crowns, bridges, inlays and veneers of fixed partial denture with different translucency levels and colors.
