5.
Keep lips, cheeks, and tongue out of the scanner’s view
:
•
Use your finger or a dental mirror to create space between the teeth, lips and cheeks.
•
Use a lip-and-cheek-retractor to keep lips and cheeks away.
•
Be careful not to scan your own or assistant’s fingers.
•
If you get lips, cheeks or tongue in the scan, make sure to delete it all, especially where they have
contact with the teeth (no surfaces should stick out from the teeth).
6.
Keep focus on
:
•
Option 1 - Look at the teeth while scanning and listen to the "clicks". If it stops clicking/capturing,
carefully move back to the area marked on the screen.
•
Option 2 - Look at the 2D image at the lower right corner. What you see here is what you scan.
Avoid lips, cheeks and the tongue to get an easy scan.
7.
When scanning is complete, inspect the result by rotating the scan.
The important areas are:
•
Preparation line (avoid interference from gingiva, saliva, blood).
•
Contact points.
•
Occlusal surfaces.
•
If an important area is missing, simply touch this area on the model, and re-start scanning from
this point.
8.
Bite Scan
:
•
Start from the second molar or at canine if you make an anterior scan.
•
While centering the 2D image on occlusion plane, slowly move the scanner tip in straight mesial
direction with equal coverage of the upper and lower teeth.
•
Scan 4 teeth for optimal alignment. This should take no more than 5 seconds.
9.
Important for good colors
:
•
Avoid the light from the dentist chair lamp pointing directly into the patient's mouth.

Tips to Obtaining a Good Scan, Preparation
SCANNING APPROACH
The best scanning method is to start with a molar, since it has greater details for easier identification.
Change the scanning angle to 35-55 degrees during scanning to allow the surfaces to overlap, if the
overlap is small, the alignment may be lost.
