What device trims stone models to neat appearance and easier to work off?

• A. Model Trimmer
• B. Wax Pot
• C. Bench Lathe
• D. Denture Teeth

Answer: (A)

Trimming stone models to a neat appearance and making them easy to work off is best done with a model trimmer. This tool is built specifically for gypsum models, using a rotating wheel (often with water cooling) to shave away excess stone quickly and precisely, producing a flat, level base and clean margins. That neat base makes the cast sit securely on an articulator and simplifies subsequent steps in fabrication. A wax pot is for melting wax, not finishing gypsum models; a bench lathe is used more for trimming and polishing wax or other materials in different contexts, and denture teeth are actual prosthetic teeth, not a trimming device.
