15.16 Scanning multiple anteriors
When scanning multiple anteriors and crossing the mid-
line, start the scanning with the highest tooth number
(Universal) or higher quadrant (ISO) to get the correct
orientation.
In intraoral scanning it is sometimes more comfortable to
scan with the scanner tip pointing towards the mesial
instead of the distal. There are a couple of options for
dealing with this situation.
• Take the first scan with the scanner pointing in the correct
direction. Turn the scanner around to a more comfortable
position and retake the first scan.
Watch the model as it applies the second scan and
ensure the scan is placed correctly. This will not work if
there is insufficient data for the system to recognize the
two scans as the same position. If the second scan aligns
correctly, continue scanning in the normal pattern.
When crossing the mid-line, lingual scans are
recommended for more data and fewer flat surfaces. After
you turn the scanner around, pay attention to where the
system places the next scan. Repeating a previous scan
can help the system recognize that the scanner has been
turned around. If the scan is placed in the wrong area,
there may not be enough data on your model to turn the
scanner around and more scans will be required.
• Take the first scan of the higher tooth number with the
scanner pointing towards the mesial or start with a lower
tooth number. In this case, the surface indicators will be
incorrect until you reach the
Margin
tab. On the
Margin
tab, turn the model around when setting the Orientation.
15.17 Scanning impressions
NOTE
Any impression material can be used. The system does
not require a particular colour or type of material.
Remove the excess impression material so that the
scanner can get closer for scanning.
