Backgrounds: Provisional or interim restorations are commonly used in dentistry during the time between tooth preparation and placement of the definitive restoration. Fabrication of an ideal provisional restoration is crucial for gum health and to protect the pulp, for prosthetically-guided tissue healing to achieve an acceptable emergence profile, for minimizing the migration of dental abutments, and for assessing the prospective form and function of the definitive prosthesis. Hence; the present study was undertaken for assessing flexural strength of two different provisionalization materials. Materials & methods: Heat polymerizing PMMA & Self-polymerizing PMMA was used in the present study. Production of standard specimen of each material was done from a mold using dental stone as an investment material.10 specimens each of auto-polymerizing and heat polymerization PMMA were used. A Vernier caliper was used as a standard measuring device to measure the dimensions of each specimen. The whole unit was then mounted on the lower jaw of the Instron testing machine. The stress applicator pin was fixed on the upper jaw of the force testing machine & three point bent test was done for each specimen. Flexural strength was assessed and compared using SPSS software. Results: Mean elastic modulus among specimens of Heat polymerizing PMMA and Self-polymerizing PMMA was found to be 784.36 MPa and 397.11 MPa respectively. Mean force required to fracture the specimen among specimens of Heat polymerizing PMMA and Self-polymerizing PMMA was found to be 0.239 kN and 0.089 kN respectively. Conclusion: Heat polymerization PMMA was more resistant in comparison to auto-polymerization PMMA. Key words: Provisional, Indirect, Direct
