360 Denture Scan Tips
- Difficult for the scanner to capture these areas. This usually results in double scanning. Try to use a scan spray. If you do not have any, it could be worth investing in. Sometimes, rubbing articulating paper on the very shiny areas can help capture them and slightly dull the shine.
- For 360 scans, ensure the wash impression does not cover the teeth; if it does, please trim it with a scalpel.

Common concerns with denture scans are distortions and stitching errors
-
What causes these errors:
- Moving too fast whilst scanning
- Not being close enough to what is being scanned
- Too high an image count
- Excess light when scanning
Moving too fast whilst scanning:
- When moving the scanner too quickly, it does not allow ample time for the scanner to pick up the data needed and can skip over some areas. This results in distortions because the scanner does not recognise the data it is picking up.
Not being close enough to what is being scanned:
- When the scanner is too far from what is being scanned, it will not capture all the data and will only see data it does not recognise, which can cause distortions. Be sure to stay as close to what you are scanning as possible. Even lightly touching what you are scanning is acceptable.
-
When scanning a hard-to-reach area, try approaching it from different angles with the scanner to get closer to the area.
Too high an image count:
- Ideally, the image count should not exceed 5,000. You will see this image count in the top right corner of the scan step you are on.
-
When the image count goes over 5,000, it is likely that scan data will be taken from other areas of your scan and may also be more difficult to post-process. Be sure to keep an eye on this as you are scanning. If you are approaching the maximum image count and still have a considerable amount of scanning remaining, it may be best to reset that scan.
Excess light when scanning
- Turning the overhead light off when scanning can help reduce excess shine on the denture
- There is a light built into the scanner, and it will be sufficient when scanning
