What is a standard approach when digital scans fail to capture margins due to patient movement?

• A. Re-scan after guiding patient and optimizing scout scan.
• B. Proceed without margins.
• C. Switch to conventional impressions only.
• D. Ignore margins.

Answer: (A)

Capturing margins accurately in a digital scan depends on a stable patient and a complete, artifact-free data set from the initial scout scan. If movement causes margins not to be captured, the best course is to pause, guide the patient to minimize motion, and perform a re-scan beginning with a refined scout scan so the margin data can be acquired clearly. This approach ensures the digital model includes precise margin geometry, which is essential for a proper fit and seal of the restoration. Proceeding without margins would compromise the restoration, and switching to conventional impressions is unnecessary unless digital capture cannot be salvaged. Ignoring margins would lead to a poor-fitting result, so re-scanning with better guidance and an optimized scout scan is the correct, standards-aligned step.
