9. Intraoral Scanning Checklist

9-1. Avoid using any strong external lighting source.

Strong external lighting can cause reflections and distort scan data. Keep the ambient lighting soft and controlled.

9-2. Ensure your mirror is clean and free of stains except mild water spots.

Debris on the scanner tip mirror can affect data capture. Please make sure it is clean before scanning.

9-3. Keep your scanning area dry (Reduce saliva and blood as much as possible).

Saliva and blood in the scanning area can cause reflections and lead to inaccuracies. Please dry the area before scanning.

9-4. Always keep the scanner tip an appropriate distance from the teeth.

If the scanner tip is too close or too far, data may not be captured properly. Maintain a consistent and appropriate distance.

10. Upper Jaw Scanning Tips

10-1. Position the intraoral scanner tip on the occlusal surface of the maxillary posterior teeth and press the Scan button to start scanning.

*Please note that if you insert the intraoral scanner into the oral cavity after pressing the Scan button, unwanted areas may be captured and interfere with subsequent scanning.

10-2. Once scanning has started properly from the occlusal surface of the posterior tooth, continue scanning toward the incisal edge of the anterior teeth.

10-3. Since the incisal edge of the anterior teeth is narrow, scan in a zigzag pattern to capture more data, including the incisal edge along with portions of the labial and lingual surfaces.

10-4. After completing the anterior scan, continue scanning to the occlusal surface of the posterior tooth on the opposite side.

10-5. Tilt the intraoral scanner toward the lingual side and scan the entire lingual area of the arch sequentially.

For best results, position the scanner so that the ratio of occlusal surface : lingual surface : gingiva appears as 1 : 1 : 1 in the Live View.

10-6. Apply the same method when scanning the buccal area. Position the scanner so that the ratio of occlusal surface : buccal surface : gingiva appears as 1 : 1 : 1 in the Live View, then sequentially scan the entire buccal (or labial) area of the arch.

10-7. It is not possible to capture every area thoroughly in a single scan pass. Rotate the scan data to identify any insufficiently scanned areas and fill them in with additional scanning.

*When scanning missing areas, do not place the intraoral scanner tip directly on the area to be filled. Instead, recognize the position from a surrounding area first, then move to the area that needs to be filled.

11. Lower Jaw Scanning Tips

11-1. Position the intraoral scanner tip on the occlusal surface of the mandibular posterior teeth and press the Scan button to start scanning.

*Please note that if you insert the intraoral scanner into the oral cavity after pressing the Scan button, unwanted areas may be captured and interfere with subsequent scanning.

11-2. Once scanning has started properly from the occlusal surface of the posterior tooth, continue scanning toward the incisal edge of the anterior teeth.

11-3. Since the incisal edge of the anterior teeth is narrow, scan in a zigzag pattern to capture more data, including the incisal edge along with portions of the labial and lingual surfaces.

11-4. After completing the anterior scan, continue scanning to the occlusal surface of the posterior tooth on the opposite side.

11-5. Tilt the intraoral scanner toward the buccal side and scan the entire buccal (or labial) area of the arch sequentially.

For best results, position the scanner so that the ratio of occlusal surface : buccal surface : gingiva appears as 1 : 1 : 1 in the Live View.

11-6. Apply the same method when scanning the lingual area. Position the scanner so that the ratio of occlusal surface : lingual surface : gingiva appears as 1 : 1 : 1 in the Live View, then sequentially scan the entire lingual area of the arch.

11-7. It is not possible to capture every area thoroughly in a single scan pass. Rotate the scan data to identify any insufficiently scanned areas and fill them in with additional scanning.

*When scanning missing areas, do not place the intraoral scanner tip directly on the area to be filled. Instead, recognize the position from a surrounding area first, then move to the area that needs to be filled.

12. Bite Scanning Tips

* The patient should be seated upright in the dental chair to obtain a proper Centric Occlusion (CO).

* Before scanning the bite, both the maxillary and mandibular scan data must already be acquired, with sufficient buccal data captured. If the buccal scan data has any holes or missing areas, errors may occur during occlusion alignment.

* Check whether any unnecessary soft tissue that may interfere with occlusion has been scanned, and if so, remove it in advance using the Trimming tool.

12-1. For full arch scans, two bite scans are recommended; for quadrant scans, one bite scan is sufficient. When taking two bite scans, it does not matter which side is scanned first.

12-2. With the patient's mouth open, insert the intraoral scanner tip into the oral cavity first, then have the patient close into occlusion.

*If the intraoral scanner tip is inserted from the buccal side while the mouth is closed, the lips and gums may be scratched and injured by the scanner.

12-3. It is recommended to start scanning with the intraoral scanner tip positioned on the buccal side of the most posterior tooth, and to continue scanning until 6–8 teeth in both the maxillary and mandibular arches have been captured, even if automatic occlusion alignment is successful.

12-4. When taking the second bite scan, scanning an area similar to the first bite scan helps with alignment.

12-5. If automatic occlusion alignment fails, you can align the data manually using the Manual Alignment feature. As shown in the image, alignment is performed by clicking three points at the same locations on both the bite scan data and the scan data you want to align with.

13. Trimming Tool

While scanning the oral cavity, soft tissues such as the tongue, cheeks, and lips, as well as the operator's hands, may sometimes be captured along with the scan data. These unnecessary areas can affect automatic alignment or cause occlusion errors, so it is recommended to remove them before completing your work. You can remove unnecessary areas using the Trimming Tool in Medit Scan for Clinics.

13-1. Polyline Trimming

This tool removes unnecessary data by drawing a polygon around it. Left-click with the mouse to create the points of the polygon, then right-click on the final point to complete the polygon and remove the enclosed area.

13-2. Brush Trimming

You can freely paint over unnecessary areas with a brush to remove them.

13-3. Quick Trimming

If an unnecessary area is separated from the main scan data, you can remove it with a single click.

13-4. If you accidentally remove a necessary area, you can use the Undo function at the bottom-left of the screen to return to the previous state.

14. Completing the Scan

Once all scanning is complete, you can finish your work by clicking the Complete icon at the top-right of the Medit Scan for Clinics screen.

Clicking the icon brings up a pop-up where you can choose from three processing options. Post-processing will proceed according to the selected option.

*Post-processing: Removes improperly captured regions, noise, and overlapping or distorted artifacts, and refines the scan data into a clean, accurate 3D digital model suitable for clinical use.

14-1. Process Data (As It Is)

This option post-processes the scan data exactly as captured, without any refinement or editing.

14-2. Fill Major Holes

This option post-processes the data by filling empty areas based on a reliability map, extending the trustworthy data around the holes to close them.

14-3. Create 3D Printable Model

This option post-processes the data by directly generating a base to create 3D model data, eliminating the need to work in the Model Builder app.

14-4. For prosthetic restoration cases or cases where even slight modifications are not permitted, select the "Process Data (As It Is)" option. For orthodontic cases or cases involving diagnostic and study models, select the "Fill Major Holes" option. For cases that require a 3D printable model, select the "Create 3D Printable Model" option.
