All or nothing Function
After merging the designed compo-
nents, the surface is finely finished.
With the end of the “Upper jaw” design
the dental technician now has the finis-
hed restoration on the screen (Fig. 30
to 31). This completes the design.
Data transfer and milling
The operator saves the finished scene
in the Ceramill Mind software. The
technician then opens the nesting soft-
ware to place the framework in the
blank by activating the Ceramill
Match2 CAM software. The software
automatically selects the material de-
termined at the beginning of the data-
base; in this case the translucent zirco-
nium oxide Ceramill Zolid. If there is no
user in the blank library or the correct
height of blank is not available, the
dental technician creates a new one,
which can be used immediately (Fig. 32
to 33).
Using the “Positioning” tool the techni-
cian places the framework in the blank
so that as much material as possible is
saved. It is cost-effective to mill as lar-
ge a number of units from one blank as
possible. The milling path is calculated
after the connectors have been che-
cked and possibly repositioned, (Fig.
34). Once this has been completed, the
operator activates the Motion2 to
transfer the milling data to the machi-
ne (Fig. 35 to 37).
When the spindle and blank holder
have been set to the zero position, the
milling process is started with a final
click on the “Start” button. The type
and size of the framework determine
the duration of the milling procedure.
In this case the dental technician can
assume approx. 45 minutes milling
time (Fig. 38 to 39). Finally, the bridges
are separated from the blank and pre-
pared for the sinter process.
In the next part of this series the au-
thors demonstrate the preparation of
the framework for sintering and also
the fit and function on the model. n
