Correct answer: E — Elimination of patient discomfort from impression material, immediate digital data transmission, and reduced storage needs

Digital impressions (intraoral scanning) offer advantages including elimination of impression material (reduced gagging, patient discomfort), immediate digital data transmission to the lab, reduced chairside time, no physical model storage, and the ability to evaluate scan quality immediately. However, they are not universally superior — subgingival margins still require adequate tissue retraction for scan accuracy, and full-arch accuracy may be limited depending on the scanner. They are increasingly becoming the standard of care for single-unit and short-span fixed prosthodontics.
