Occlusal scan

Important: Ensure that the distance between the coated sapphire glass
of the scanner and the scanned surface is observed.
The distance must be between 0 - 15 mm (ideally: 5 mm). The scanner
does not rest on the teeth or the gums. If the distance is too great, no
data will be obtained.
1. Move the scanner to the starting position. For this purpose, the
scanner 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, move the scanner slowly 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.
5.5.2

Buccal scan

ü The scanner is on the adjacent tooth, in the mesial direction to the
preparation.
1. Rotate the scanner between 45° to maximum 90° toward the
buccal.
2. Guide the scanner 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 scanner is held like a flute during buccal scans. Do not
tilt it vertically to the direction of motion.
Tip: Practice guiding the scanner between 45° and 90°.
