Which tool is used to cut and carve acrylic denture bases and teeth?

• A. Denture Teeth
• B. Bench Lathe
• C. Wax Spatulas and Carvers
• D. Model Trimmer

Answer: (B)

The bench lathe is the tool you use to cut and carve acrylic denture bases and teeth. It spins a cutting or polishing wheel at controlled speeds, which lets you trim flash, shape the base borders, and contour or refine the surfaces of the denture acrylic with precision. Using a bench lathe provides cleaner, smoother results and better control than trying to do this by hand. Wax spatulas and carvers are intended for manipulating wax patterns during the setup stage, not for finishing processed acrylic. A model trimmer is used to trim plaster or stone models, not to shape the denture itself.
