With the advent of newer provisional crown and bridge material it has become imperative to evaluate their strength and know the tissue response of these materials in order to select the appropriate one. This study takes a comparative view of two commonly used acrylic resin materials i.e. self polymerizing poly - methyl methacrylate (PMMA) and heat polymerizing poly - methyl methacrylate with a newly introduced composite resin Protemp-II, claiming better handling, strength and esthetics. To simulate the oral condition, the fracture resistance of selected materials was tested by three point bent test on Instron testing machine. The highest values for fracture resistance were displayed by heat polymerized PMMA followed by Protemp-II and self polymerized PMMA.
