UP.CAD is lithium disilicate glass–ceramic block, which is designed for CAD/CAM applications.
This type of CAD/CAM ceramic block is produced in a crystalline state, giving it its lilac colored
appearance, and making it easy to be machined by CNC equipment. After milling is completed, a
porcelain furnace is used to crystallize the material at temperature of between 840–850 °C. The
crystallization process takes about 25 minutes, depending on the furnace used, and the shrinkage
during the crystallization process is minimal.

2） Types：
UP.CAD blocks have been divided it into four categories according to their respective
translucency characteristics：HT(High translucency, VA –VD 16 color system , LT （Low
translucency, VA –VD 16 color system), MO（Moderate opacity，VMO0–VMO4), HO（High
opacity,VHO0–VHO2).
Note：Each kind of translucency has 3 sizes in the respective order: 15–12–10；18–15–13；55–19–15.
