Lingual scan

ü The CEREC Omnicam is on the tooth that is positioned next to the
preparation in the distal direction.
1. Rotate the CEREC Omnicam from 90° in the buccal direction to
around 45° to maximum 90° in the lingual direction on the other
side.
2. Guide the CEREC Omnicam over the entire lingual distance in the
mesial direction over the prepared tooth.
7.4.4

Approximal surface scan

Scan the approximal surfaces of the prepared tooth.
➢ Move the CEREC Omnicam 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.
