ST-C is a pre-shaded zirconia disc for CAD/CAM milling. The tooth colour is already in the material, so restorations need little or no colouring liquid in the lab; the disc is still compatible with Zirdent's colouring liquids. Zirdent gives a flexural strength of 1100 MPa and a translucency of 42%.
Indications
Zirdent lists anterior copings and 3-unit coping bridges, posterior full-contour crowns and 3-unit bridges, implant crowns, Maryland bridges, full-contour zirconia bridges of more than four units, and inlays.
Formats
ST-C is made from Sinocera® zirconia powder and comes in 98 mm, 95 mm and 92 × 75 mm formats, 10–25 mm thick.
