Which statement describes a challenge for digital impressions in certain patient populations?

• A. Long-span edentulous areas may pose problems.
• B. They always require less time.
• C. They cannot be used with any dentists.
• D. They replace all clinical examinations.

Answer: (A)

Digital impressions rely on stitching many images together using recognizable landmarks from teeth and surrounding stable tissues. When there are long-span edentulous areas, there aren’t enough reliable reference points to guide that stitching, and the soft tissue in those regions can move, which can lead to stitching errors and reduced accuracy. This makes long edentulous spans a real challenge for capturing precise digital impressions in certain patients. That’s why this option is the best choice. Digital impressions aren’t universally quicker in every case—they can take longer when such regions complicate the scan. They’re used by many practitioners and do not replace the need for a clinical examination, which remains essential for planning and verification.
