Prosthetic information can be entered before scanning through the indication settings within the project.

The entered information is transmitted together with the scan data when connected to partner.

📌FREEDOM Air Half-Arch Prosthetic Scan Strategy 

To obtain accurate data, proper preparation and scan strategy are essential.

Before starting the scan, make sure to review the FREEDOM Air Pre-scan Checklist and Scan Preparation.

 

1. Half-Arch Scan Strategy

For single crowns or inlay/onlay cases, a half-arch scan is sufficient to obtain all necessary data for prosthesis fabrication.
In these cases, perform the occlusion scan within the same half-arch.

  • Half-arch scanning begins with the occlusal surface, progressing to the lingual and buccal surfaces.

  • Keep each scanning stage under 1 minute.

  • If the scan data is not properly captured during scanning, a red box will appear on the screen.
  • When this occurs, return to the previously scanned area, refocus, and resume scanning from that point.

2. Prep And Adjacent Teeth Scan Strategy

- Check margin condition before scan 

Before intraoral scanning, check the patient’s oral condition. Excessive blood or saliva can affect the scan data, so blood and saliva must be removed prior to scanning.

Since the intraoral scanner captures the oral condition as it is, gingival isolation is required in cases with subgingival margins or unclear margins to ensure accurate margin data acquisition.
Common isolation methods include gingivectomy using a laser or the use of cord.

Improper Oral Environment Proper Oral Environment

- Active the Confidence Map 

Activate the ‘Confidence Map’ tool when scanning the prep and adjacent teeth, and scan thoroughly to ensure that no data is missing.

The prep and adjacent teeth should be scanned until all blue highlighted areas on the Confidence Map disappear.

  • When the Confidence Map is activated, areas with insufficient scan data are displayed in blue.
  • Scan the prep and adjacent teeth thoroughly until all blue areas disappear.

3. Occlusion Scan Strategy

- Patient Position:

  • Occlusion scanning must be performed while the patient is in centric occlusion.

  • To obtain accurate occlusal data, the patient should be in a sitting position, not lying down.

- Preparation Before Occlusion Scanning:

  • Before performing the occlusion scan, have the patient open their mouth and position the scanner on the buccal side.

  • Have the patient close into occlusion several times to check the centric bite position in advance.

  • Review the buccal surface data of both the maxilla and mandible before starting the occlusion scan.
    - If buccal data are insufficient or excess soft tissue is present, the occlusion may not align correctly.
    - If there are holes or missing data, perform additional scans.
    - Delete unnecessary soft-tissue data before proceeding with the occlusion scan.

- Half-Arch Occlusion Scan:

  • Scan 4 to 6 teeth starting from the terminal molar, excluding the wisdom tooth.

  • Move the scanner up and down while rotating, ensuring that both the teeth and surrounding gingiva are captured.

  • When the software displays a message indicating that occlusion alignment is complete, end the scan.
    - However, if the alignment is not yet accurate even after the message appears, continue scanning for an additional 2–3 seconds before stopping.

  • Occlusion scanning must be performed only within the corresponding half-arch range.

⚠️Precautions During Occlusion Scanning⚠️

Accurate occlusal data cannot be obtained if the patient moves their teeth during scanning.

- Ensure the patient maintains a stable centric occlusion throughout the scan.

Scanning an excessively wide area during bite scan acquisition may reduce the accuracy of the occlusion data.

- For bite scans, set the scan area to include only 4–6 teeth in total from the upper and lower arches.

Before performing the occlusion scan, have the patient open their mouth and position the scanner on the buccal side.

- If the scanner is positioned on the buccal side while the patient is in occlusion, unnecessary areas such as the lips or cheeks may be captured, resulting in inaccurate occlusion data.
