Advantages of Dental Composite Resins:

# The main advantage of composites over unfilled direct filling resin is their: (KAR-97)
a) Higher solubility in saliva
b) Lower modulus of elasticity
c) Esthetic excellence
d) Lower thermal co-efficient of expansion


The correct answer is D. Lower coefficient of thermal expansion.

Advantages of composites over unfilled resins:
  • Lower coefficient of thermal expansion
  • Low polymerization shrinkage
  • Low water absorption
  • High abrasive resistance
Disadvantages of composites:
  • Less color stability
  • Less smooth finish than unfilled resins
