CAD/CAM (computer-aided design/manufacturing) digital impression has which financial advantage compared to traditional methods?

  1. Reduces the cost of shipping impressions to the laboratory
  2. Avoids the cost of buying a milling unit
  3. Eliminates the need for a dental laboratory entirely
  4. Is less expensive than purchasing gypsum stone
Show answer and explanation

Correct answer: D. Is less expensive than purchasing gypsum stone

  • A. Eliminating shipping is a time/logistics benefit but may not be the primary FINANCIAL advantage.
  • B. CAD/CAM actually requires purchasing a milling unit — this is a cost, not a saving.
  • C. CAD/CAM does not eliminate the laboratory — restorations are still fabricated.
  • D. Correct. Intraoral scanners eliminate the need to purchase gypsum stone for traditional model pouring. This is a direct material cost saving over conventional impression-taking. Note: the scanner and milling unit have upfront costs, but material cost (no gypsum) is a recognized advantage.
