Metal Scan Guide
Perform the scan according to the following steps.
1. Calibrate the scanner.
2. If there is a bright external light source, such as a dental light, that may interfere with the scan area, adjust the angle of the light or temporarily turn it off. Strong external light reflected from the metal surface may interfere with scanning.
(However, it is not necessary to turn off the entire operatory lighting.)
3. Check that the “Metal Scan” feature is turned on.
(Settings > Scanning Performance > Metal Scan)
When metal restorations, such as crowns, occupy a certain percentage or more of the scan area, parameters optimized for metal scanning are automatically applied.

4. Check that the Active Noise Filtering (beta) feature is turned on.
(Settings > Scanning Performance > Active Noise Filtering (beta))
During scanning, noise displayed in metal areas and empty space is removed. Any noise that is not removed during scanning is removed after scanning is stopped.
5. Before scanning, completely dry any moisture or saliva on the metal surface.
6. Select “Reliability Map” in “Data Display Mode.”
While scanning with “Reliability Map,” check the reliability of the acquired scan data in real time. To make sure sufficient data has been collected, scan the area from various angles for approximately 2–3 seconds. Scan with the tip positioned close to the scan target.
ℹ️ Note
If light is projected at a right angle directly onto metal, such as a gold crown or amalgam, the light is reflected like a mirror directly into the scanner’s mirror and sensor. After scanning the adjacent teeth or the Preparation area first, scan the area around the metal by slowly and steadily rolling the scanner to acquire data from various angles.
7. If the data for the metal restoration area is still insufficient, click the “Optimize” button to align the acquired scan data and continue scanning.
Ceramic Scan Guide
The ceramic scanning method is basically the same as the metal scanning method.
However, the “Metal Scan” feature mentioned in Step 3 of the Metal Scan Guide does not apply to ceramic scanning. Therefore, skip Step 3 and proceed directly from Step 4.
