How does CAD/CAM impact accuracy and efficiency in the dental laboratory?

• A. It reduces accuracy and slows workflow
• B. It eliminates the need for staff
• C. It improves fit precision, reduces human error, speeds workflow, and allows easier replication, though it requires investment in technology and training
• D. It has no impact on efficiency

Answer: (C)

CAD/CAM changes the workflow from manual steps to digital design and automated fabrication, which directly boosts accuracy and efficiency. Digital impressions and design software let margins, contacts, and occlusion be defined with precise measurements, improving how well a restoration fits. The manufacturing process—whether milling or 3D printing—reproduces those designs with controlled tolerances, reducing variations that come from traditional pouring, waxing, and manual finishing, and thus cutting down human error. The digital approach also streamlines operations: once a restoration is designed, it can be rapidly replicated or adjusted, speeding production and making it easier to reproduce exact fits for multiple units or patients. Of course, these gains come with upfront trade-offs. There’s a need to invest in hardware and software—scanners, CAD programs, and milling or printing equipment—and to train staff to use the technology effectively.
