Sterilization considerations apply to acrylic denture flasks.

• A. Use disposable only and do not autoclave.
• B. Autoclave at the highest setting regardless of guidelines.
• C. Ensure compatible with heat/steam; follow manufacturer guidelines for autoclave cycles; avoid warping by using appropriate pressure/time.
• D. Sterilization always damages acrylic; skip autoclave.

Answer: (C)

Sterilization methods must be compatible with the materials in an acrylic denture flask, because heat and steam can deform or distort acrylic if exposed to cycles beyond what the material can tolerate. The best approach is to verify that everything in the flask (the acrylic itself and any components like plaster, metals, or elastics) is compatible with heat and steam, and then follow the manufacturer’s autoclave guidelines for temperature, time, and cycle type. Using the right cycle avoids warping by controlling the pressure and duration, ensuring sterility without compromising the flask’s shape. Think about why the other options aren’t suitable: relying on disposable flasks and skipping autoclaving ignores the reality of reusable flasks in many lab workflows. Autoclaving at the highest setting ignores material limits and can cause distortion. And the notion that sterilization always damages acrylic is not accurate; with proper guidance and cycles, acrylic can be sterilized without damage.
