The materials tested were as follows: heat-polymerized
PMMA (A), heat-polymerized PMMA reinforced with
polyether fibers (B), cold-polymerized PMMA (C), coldpolymerized
PMMA reinforced with polyether fibers (D),
cold-polymerized bis-acrylic (E), and cold-polymerized bisacrylic
reinforced with polyether fibers (F). Thirty samples
were fabricated (five samples in each group) to analyze the flexural
strength and modulus of elasticity of the different materials
used in the manufacture of the provisional restoration of
the interim FPDs.
