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.
