Correct answer: A — Computer-aided design and computer-aided manufacturing
Explanation lettering: E = shown as C · C = shown as E
The correct answer is A: computer-aided design and computer-aided manufacturing. In a dental CAD/CAM workflow, clinical geometry is first acquired, for example by intraoral or laboratory scanning. CAD software is then used to design the restoration, and CAM equipment converts that design into a physical restoration, commonly by milling. Scanning is therefore the data-acquisition stage rather than CAD itself. Ceramic and composite are possible restorative materials, so option B confuses materials with the acronym. Option D is too narrow because CAD/CAM is not restricted to crowns and bridges. Options C and E describe unrelated clinical or mechanical concepts.
