1200MPA 98mm 95mm Dental Zirconia Disc For Yenadent Machine System
Mililng Zirconia High Translucency Zirconia For Yenadent Machine System
Instructions for use Honchon zirconia High translucent Zirconia
YUCERA HT (high translucent) can be used for coping crown and framework. The following instructions provide general guidelines for designing, milling, coloring, sintering, porcelaining and glazing and should be followed very carefully to avoid any loss of aesthetics, fit, durability or overall quality.
