Scan Stage Tools

The following tools are provided at the bottom of each scan stage.

Basic Scanning Tools

	Start	Start the scan. The user can also start the scan by pressing the Scan button on the scanner.
	Stop	Stop the scan. The user can also stop the scan by pressing the Scan button on the scanner.
	Optimize	Align 3D images for a more accurate scan. All the noise will be removed after optimization.
	High Resolution Scan	Acquire high-resolution scan data for entire or partial scan data. The high-resolution and standard-resolution scan data are smoothly merged in post-processing. * Unavailable with i600
	Import Scan Data	Import 3D data from Medit Link.
	Delete	Delete scan data for the current stage. All data that are related to the current stage can be deleted.
	Undo	Cancel the previous scan.
	Redo	Restore the canceled scan.

High Resolution Scan

* unavailable with i600

Please refer to the following comparison between the high-resolution and standard-resolution scan data.

Texture On	Texture Off

Import Scan Data

This feature allows the users to import scan data acquired by third-party scanners. You can edit the data or perform additional scanning with the imported data.

1. Click the "Import Scan Data" icon.
2. Choose a file from a Medit Link case.
3.  Trim the part needing a rescan.
4. Perform addition scanning.
   

Filtering Tools

	Smart Scan Filtering	Filter unnecessary soft tissue data while scanning. Three filters are available for Smart Scan Filtering. No Filtering Teeth + Gingiva Intense Teeth + Gingiva Teeth
	Smart Color Filtering	Filter specific colors from being scanned. You can add and manage the color to filter.
	Smart Stitching	Acquire and align scan data freely, regardless of your scan strategy. Data is automatically aligned while scanning and can be manually aligned after scanning stops.

Smart Scan Filtering

This feature removes unnecessary soft tissue data while scanning, depending on the selected filter. Three filters are available for your convenience.

	No Filtering	Soft tissue remains intact. This option is useful for edentulous arch or plaster model cases.
	Teeth + Gingiva	Remove soft tissues that interfere with the scan, leaving only the necessary teeth and gingiva. You can use this option for most of the general scan cases.
	Intense Teeth + Gingiva	Remove soft tissues that interfere with the scan, leaving only the necessary teeth and gingiva. This option only acquires gingiva data within a certain distance from the tooth and excludes other soft tissues away from the teeth.
	Teeth	Remove all soft tissues and gingiva, leaving teeth only. This option is effective when scanning only the teeth as an additional scan after using the "Teeth + Gingiva" filter for initial scanning.

Smart Color Filtering

The "Smart Color Filtering" option prevents the scanning of alien materials (e.g., gloves, etc.) in the intraoral environment by registering their colors. Once the colors are registered, and the option is turned on, the colors will automatically be filtered out during the scanning process.

1. Turn on filtering by clicking the "Smart Color Filtering" option at the bottom.
2. To register a new color, click the "Add a Color" icon.
3. The Smart Color Filtering dialog appears.
4. Prepare the material to be filtered out. Then, press the Scan button on the scanner to start the color recognition process.
5. Click "Confirm" to register the color and complete the color registration.
6. You can turn on or off each color filter by clicking the color icons.
   
7. The registered colors will be shown on the icon and saved for all scan stages unless you change them.
   

Smart Stitching

For 3D scanning using the video recording method, it is important to scan continuously so that the camera does not lose focus during the process of acquiring scan data.

This process is highly dependent on the user's skill and the condition of the patient's mouth, but the scanning method supported by Smart Stitching can eliminate this inconvenience.

1.  Turn on the "Smart Stitching" icon at the bottom.
2. Start scanning in the stage that supports Smart Stitching, Pre-Op.
3. When the scanner is placed in a non-contiguous area with the acquiring scan data, new scan data will be acquired. At this time, the previously scanned data is displayed as a thumbnail in the lower left corner.
   
4. On the left corner of the screen, you can have up to five thumbnails of the previous scan data.
   • You can click each thumbnail to view the data at the center of the data display area, and the previously displayed data is added to the thumbnails.
   • You can click the trash icon on each thumbnail to delete each one of them or the "x" button at the bottom of the thumbnail list to delete all thumbnails.
5. During scanning, if the scanner gets new data in an unaligned scan data area, it will automatically attempt to align, and any thumbnails of aligned data will disappear.
   
6. The following message may appear when you try to exit the stages when unaligned scan data exists.
7.  To align all scan data, conduct one of the following:
   • Scan additional data to get more data for automatic alignment.
   • Use the Manual Alignment tool to align data.
   • Delete all or part of the scan data that isn't aligned.
8. Data acquisition is completed when all unaligned scan data is aligned, as shown below.

Advanced Tools

	Impression Scan	Provide seamless scanning to combine intraoral and impression scan data. Easily merge the intraoral and impression scan data with the integrated scan. * Refer to Case and Workflow Examples > Impression Scan for a detailed description of how to use the tool.
	Abutment Library Matching	Manage custom abutment libraries. This library data is aligned automatically with the scan data, minimizing the need to scan difficult-to-reach areas. * Refer to Case and Workflow Examples > Abutment Library Matching for a detailed description of how to use the tool.
	Scan Body Library Matching	Manage pre-set and custom scan body libraries. This library data is aligned automatically with the scan data, minimizing the need to scan difficult-to-reach areas. The library data can be shared for further processes, such as design. * Refer to Case and Workflow Examples > Scan Body Library Matching for a detailed description of how to use the tool.
	Mandibular Movement	Record and replay the patient's mandibular movement. * Refer to Scan Stages > Occlusion > Additional Tools for Occlusion Stage > Mandibular Movement for a detailed description of how to use the tool.
	Preparation Review	Check whether the tooth preparation is done within the pre-set value range. You can check the prepared tooth data with insertion path and distance measurements. * Refer to Case and Workflow Examples > Preparation Review for a detailed description of how to use the tool.
