·www.dlonline.deaccurately establish which functional
parameters should be incorporated in
the restoration.
In addition to the patient parameters
supplied, the dental technician can
mechanically determine the incisal and
canine guidance with the aid of the
customised incisal guidance unit (Fig.
23 to 30) and also reproduce this later
using the virtual articulator.
The illustrations clearly illustrate which
differences arise during the design of
functional surfaces if the incisal gui-
dance is lost due to preparation of the
anterior teeth and the technician incor-
rectly engages posterior tooth guidan-
ce (Fig. 31 to 33).
Once the requirements for a functional
restoration are created in the analogue
world, the way is optimally prepared
for a successful restoration in the digi-
tal world.

The next issue deals with the different
Artex articulators, their calibration,
customised incisal guidance table as
well as their customised programming
and 1:1 transfer of the patient data in
the Ceramill CAD/CAM system.
