In a dental laboratory, 3D printing is commonly used to produce which of the following?

• A. Fabricating surgical guides, rapid prototyping models, and provisional restorations
• B. Printing dentures only
• C. Not used due to accuracy concerns
• D. Replacing all traditional processes

Answer: (A)

3D printing in a dental lab is commonly used to create items that benefit from patient-specific geometry and quick turnarounds. Surgical guides require precise fit and alignment to assist implants, which 3D printing can provide reliably. Rapid prototype models help with planning, communication with the patient, and verifying margins or occlusion before final work. Provisional restorations can be produced directly from digital designs for temporary use while final restorations are being made, saving time and enabling proper aesthetics and fit during the interim.

While dentures can be made with 3D printing, and the technology continues to grow, the broader and more typical applications include guides, models for planning, and temporaries. It’s not used to replace every traditional process, as some steps still rely on conventional techniques and materials.
