To cure a heat cure resin, a proper heating cycle is necessary_____________?
Correct answer: C. To prevent the porosity
- A. To prevent volume expansion
- B. To prevent warpage
- C. To prevent the porosity
- D. All of the above
Explanation
A controlled heating cycle prevents the monomer from boiling, which is the main cause of porosity in heat-cured acrylic resin. Warpage is more closely related to processing stresses, flask separation, and uneven cooling.
