Which device holds water heated to a desired temperature and is filled with air to pressurize for curing acrylic?

• A. Wax Pot
• B. Model Trimmer
• C. Pressure Pot
• D. Denture Base Acrylic

Answer: (C)

Heat and pressure during curing of denture base acrylic reduce porosity and improve strength. A pressure pot is the device designed for this process: it holds the acrylic in a sealed chamber that is kept in a heated water bath, while air is used to pressurize the chamber. The combination of controlled heat and pressurized air forces monomer more uniformly and pushes out trapped air and moisture, producing a stronger, smoother base with fewer pores. This setup is specifically for curing; other equipment serves different functions—one for heating wax and another for trimming models—while the denture base acrylic is the material being cured, not the device itself.
