6 Application Tips
6.1 Fixator
When using the fixator for patient cases with suf-
ficient remaining dentition (assured occlusion),
thus ensuring sufficient jaw support:
▷
Do not tighten the rear screw of the fixator.
This ensures maximum, optimal interlocking of
the jaws during the scan process.
When using the fixator for patient cases where no
support of the jaws can be achieved through the
remaining dentition (terminal occlusion):
▷
Articulate the models with the supporting pin
position set to zero.
▷
Tighten the rear screw of the fixator.
6.2 Positioning the Model
The model must be positioned with the spacer
plates in such a manner, the it is within the scan
focus. In the scanner, the scan focus is located on
the level of the tilting axis. For correct positioning,
it is recommend to use the provided measuring
template.
▷
Position the measuring template on the upper
side of the tilting axis.
▷
Check if the areas of the jaw model to be
scanned are within the marked measuring range.

Using the No Plast Model Retainer
▷
Affix the model in the No Plast model retainer.
▷
Loosen the screws in the center part of the No
Plast model retainer and align the model in the
scan focus.
▷
Lock the position with the knurled screw and
then additionally tighten the Allen screw with
the Allen key.
The tiltable upper element of the fixator
may not be put into the scanner when not
secured (affixed)!
▷
Always tighten the lateral screw of the
fixator.
NOTE:
Faulty automatic assignment of jaw models!
▷
When using the fixator (also applies for jaw
scans), only place models with plaster base in
the scanner!
