Lingual scan

ü The scanner is on the tooth that is positioned next to the
preparation in the distal direction.
1. Rotate the scanner from 90° in the buccal direction to around 45° to
maximum 90° in the lingual direction on the other side.
2. Guide the scanner over the entire lingual distance in the mesial
direction over the prepared tooth.
5.5.4

Approximal surface scan

Scan the approximal surfaces of the prepared tooth.
➢ Move the scanner in the occlusal direction to the prepared tooth.
Acquire the approximal surfaces in the distal and mesial direction by
using a wave motion in the occlusal, buccal, and lingual direction
over the prepared tooth.
To do so, tilt the surface by 15° in the distal and mesial direction to
gain a better view of the approximal contacts.
Notes:
● Remove the soft tissue.
● Cut away the moveable gingivae, so that only 2-5 m m gingivae
remains around the tooth.
● When performing this activity, be careful not to accidentally cut out
any areas that e.g. are located behind the model or are otherwise
cut away from the line.
● This cut must be completed during the ACQUISITION phase using
the cutter.
