Scan Buccal Bite; Model Alignment - Planmeca PlanScan User Manual

Scan Buccal Bite

1 Click Scan Buccal Bite.
2
Press the articulated model down firmly or have the patient bite down firmly and tell them
not to move while you are scanning. If they shift during the scanning, the alignment may be
incorrect.
3
Scan at a 90° angle to the teeth. Scan the sides of the teeth that were captured in the
preparation and opposing models. Ensure some gingival data is captured.
4 Click Generate Model or press M on the keyboard. The system generates the model and
attempts to align to the other scanned models. The software should automatically align the
models. If the Align Buccal is red, see below for instructions on manually aligning the data.
Your model should resemble the following. Ensure there is good data on the buccal sides of the
teeth. Intraoral scans will most likely have the tongue in the background. Model scans will have
space filler in the gaps.
5 Erase any excess data from the model.

Model Alignment

The alignment icons are on the right side of the screen. There is a different icon for each
alignment type: Buccal Bite, Pre-op, and Bite Registration. The system attempts to automatically
align the models as they are generated. A green dot means the scans are aligned. A red dot
means they are not aligned.
Click the icon to view the alignment. All of the alignment icons have a Refresh button. Click
Refresh to reset the alignment and manually align the models. Automatic alignment should be
used in most cases.
If there is extra data that might be interfering with the scans (tongue, cheek, etc.), try trimming
the extra data before manually aligning.
The buccal bite model is translucent on the Alignment screen to aid in evaluation. The buccal
bite has an extra Show/Hide Buccal option. This enables you to hide the buccal bite model and
evaluate the opposing and prep models.
