Scanning
Once you establish the scanning strategy for the case, you will automatically move on to the Scan stage.
The Scan stage consists of sub-stages such as Maxillary Base, Mandibular Base, Flexible Multi-Die, Prepared Tooth (Maxilla), Prepared Tooth (Mandible), etc.
- The order of each sub-stage can be changed. The changed order is saved and can be applied when you scan next time.
New Scan
Scan the items corresponding to each sub-stage of the Scan stage in the order of the stage icons.
1. Before scanning, ensure that the model faces the cameras and that the same articulator type is set for all linked programs such as Medit Link, design programs, etc.
2. Place the model in the scanner.
3. Select a scan path for the scanning process. You can skip this step if you want to use the default scan path or when the "Perform Additional Scanning Automatically" option is enabled on Settings > Table Top Scanner > Additional Scanning.
4. Click the "Scan" icon at the bottom.
The Space key is set to Scan by default. You can configure the shortcut keys for Medit Scan for Labs in Settings.
5. Before the scan starts, you will be asked to adjust the scan area.
6. Drag to move the blue line to set the appropriate height and click the "Confirm" button.
Please make sure that the model fits the camera view in all directions.
You can adjust the axes of the scanner by clicking the up/down buttons at the window's top right corner.
7. The scan starts according to the specified scan path. Do not touch the scanner while the scan is in progress. It will take a few seconds to complete.
8. Click the "Next" button at the top left corner of the data display area to move to the next scan stage.
Re-Scan
1. Click the "Scan" icon at the bottom after your scan is complete.

Additional Scanning
Automatic Additional Scan
The program can automatically identify areas needing additional scans based on the acquired data.
You can turn on or off the "Perform Additional Scanning Automatically" option on Settings > Table Top Scanner > Additional Scanning and set when to start automatic additional scanning.
1. Once the initial scanning is completed, the program will ask the user to confirm to start additional scanning.
2. Click "Start Now" to start automatic additional scanning. Even if you do not click the button, additional scanning will start after the set time elapses.
3. In some stages, the process of 1-3 above is repeated several times.
4. After the automatic additional scan is completed, the user can check the scan data and perform "Add Scan" if the scan data is still insufficient.
Manual Additional Scan
With the "Additional Scan" icon at the bottom of the screen, you can get additional data on the specific area of the model without replacing the existing scan data.
1. Rotate the model to bring the missing spot to the front. You can double-click on the missing spot to turn the cameras to face the empty spot.
2. Click the "Additional Scan" icon at the bottom.
3. The empty spot will be filled after the table top scanner acquires additional scans.
4. If you rotate the model and click "Additional Scan" during an additional scan, it will be scheduled for the next additional scan so you can scan continuously.
Scan Using Intraoral Scanner
You can also use an intraoral scanner to get additional scan data.
1. Connect the intraoral scanner to the computer.
2. Check the scanner status to see if the scanner is calibrated.
3. Click the "Scan Using the Intraoral Scanner" option at the bottom.
4. Place the scanner tip on the empty spot and scan the model.
5. The empty spot will be filled after you acquire additional scans with the intraoral scanner.
Add Another Scan Body
You can perform an additional scan body scan after placing scan bodies on the different teeth. This function is useful when you do not have enough scan bodies.
For example, here we have a case that requires four scan bodies, but you only have only two scan bodies available.
1. Place the two scan bodies on the model, and click the "Scan" icon.
2. You will get the scan data with two scan bodies on.
3. Move the two scan bodies to the other two positions on the model, and click the "Add Another Scan Body" button.
4. The program will perform additional scans to complement the existing data.
