How to Prevent Intraoral Scanner Lens Fogging During Scanning?

If your intraoral scanner lens fogs during scanning, pause the scan and check the scanner heating and protective glass.

1. Wait for the scanner software to complete the handpiece preheating cycle before scanning.
2. Check that the scanner tip is installed correctly and that the heating contacts are clean and undamaged.
3. Blow gently on the protective glass as a quick breath test. If the glass stays clear, resume scanning.
4. If fogging returns, stop using the scanner, clean and disinfect the tip according to the user manual, and contact CEDU support for a hardware check.

These steps apply to the OScan intraoral scanner. For recurring lens fogging, include the scanner model and a photo or video when contacting support.
