All or nothing
Function
The operator can view the optimised
guide surfaces with the superimposed
diagnostic model (Fig. 21 to 24). The
fully anatomical shape of the frame-
work can be reduced to a defined di-
mension using the next tool. The guide
surfaces should be highlighted in co-
lour, so that they are maintained in the
framework material. Viewed palatally
they remain like islands on the frame-
work. These surfaces guarantee that
movements in the mouth are physiolo-
gical (Fig. 25 to 26). The sharp edges
or slight irregularities are again smoo-
thed using the “Freeform tool”. The
finer the surface is the more precise
the subsequent milling result (Fig. 27).
The dental technician places the
connectors between the reduced co-
pings and pontics as the final compo-
nent of the design. The focus is also on
functionality and stability when pla-
cing the connectors. The diameter of
the individual connectors depends on
the material and design. In this case –
two three-unit anterior bridges each
with one translucent
zirconium Ceramill
Zolid pontic – a mini-
mum of 7 to 10 mm2
cross-section surface
should be allowed
(Fig. 28 to 29).
