15.15 Scanning an anterior
The scanning pattern for anteriors is similar to the
posteriors. Since there is more varying data on the lingual
side, it is recommended to scan the linguals before the
occlusals.
Anterior teeth are often very similar to each other. To
lowers the chances of misalignment follow the suggested
scanning steps. The scanning method is the same for all
anteriors.
When scanning intraorally, it may be more comfortable to
have the scanner tip pointing towards the mesial instead
of the distal. In this case, the surface indicators on the
model will be incorrect until the orientation is changed.
1. Start on the Prep and scan the occlusal of the prep and
the mesial proximal.
2. Rotate to the lingual and scan the prep and proximals.
3. Rotate across the distal proximal to reach the facial side.
4. Scan the facial side.
Watch the model as it processes to ensure the scans are
applied to the correct area. Anterior teeth are often very
similar to each other. Following the suggested scanning
steps lowers the chances of misalignment. The scanning
method is the same for all anteriors.
When scanning intraorally, it might be more comfortable
to have the scanner tip pointing towards the mesial
instead of the distal. In this case, the surface indicators on
the model will be incorrect until the Orientation is
changed.
Optional additional scans
Evaluate your model. When you have long and straight
anterior teeth, additional facial scans are sometimes
needed to capture all of the data.
With the proximal or preparation in the centre of the circle,
take 2 to 3 scans as you gradually rotate down the facial
side of the tooth.
For optimal design, more scans of the proximals may be
desired. To evaluate the model
5. Click Data density view to verify the integrity of your
model.
Rescan any dark areas on the preparation or proximals.
6. When finished with scanning click the Margin button.
Alternate scanning pattern
To roll back and forth over the straight and long anterior
teeth you might use a “saddle” pattern. This pattern can
help avoid misalignments when scanning very similar
teeth.
