Occlusal scan

Important: Ensure that the distance between the coated sapphire glass of
the CEREC Omnicam and the scanned surface is observed.
The distance must be between 0-15 mm (ideally: 5 mm). The camera
does not rest on the teeth or the gums. If the distance is too great, no data
will be obtained.
1. Move the CEREC Omnicam to the starting position. For this purpose,
the CEREC Omnicam is in the occlusal view of the tooth, which is
next to the prepared tooth in the distal direction.
2. Scan in the mesial direction. To do so, slowly move the CEREC
Omnicam in the occlusal direction from the distal-positioned tooth
over the prepared tooth to the mesial-positioned tooth.
With full jaw acquisitions, the scan sequence is different for the transition
to anteriors. Scanning begins with the lingual and labial areas, before
moving on to the incisors.

Buccal scan

✔
The CEREC Omnicam is on the adjacent tooth, in the mesial direction
to the preparation.
1. Rotate the CEREC Omnicam between 45° to maximum 90° toward
the buccal.
2. Guide the CEREC Omnicam over the entire buccal distance in the
distal direction over the prepared tooth.
With full jaw acquisitions, limit the buccal scan to no more than a
quadrant.
Ensure that the CEREC Omnicam is held like a flute during buccal scans.
Do not tilt it vertically to the direction of motion.
Tip: Practice guiding the camera between 45° and 90°.
