Excessive temperatures during acrylic processing

# Excessive temperatures during acrylic processing may result in:
A. Discoloration of acrylic
B. Excessive shrinkage
C. Excessive expansion
D. Evaporation of acrylic monomer

The correct answer is D. Evaporation of acrylic monomer.

Excessive temperature during the acrylic processing will make the monomer boil, causing it to evaporate, creating porosities.

Porosities created by monomer evaporation will make the acrylic denture base weaker in both its chemical composition and physical durability. 

The end result is a poorly fabricated denture with voids and an inaccurate fit.
