They are used for manufacturing permanent and removable pros-
thetic restorations (e.g., crowns and bridges, conical/telescopic
crowns, supra-constructions, etc.) using CNC milling machines (e.g.
Ceramill Motion) or manual copy milling machines (e.g. Ceramill Base
and Multi-x). After the specified final sintering, Ceramill ZI meets the
requirements of the standard DIN EN ISO 6872:2009, and after
appropriate further processing (see page 26 ff.) the requirements
under ISO 13356:2008 are also complied with.
