Statement of problem: Provisional restorations play a critical role in the success of restorative treatment so they must maintain their integrity in the oral environment throughout the diagnostic and restorative phases.

Purpose: The aim of this study was to compare and evaluate the hardness of four different materials used fabrication of interim restoration.

Material and methods: Ten samples with dimensions of 10mmx10mmx2mm were fabricated from four interim materials (DPI, Tempron, Protemp 4 and Transcan). Hardness of samples was measured using Fischer scope hardness tester.

Result: The highest mean hardness was found in Heat polymerizing acrylic resin group. ANOVA test indicated F value to be 2201.01 which was highly significant (p < 0.001).

Conclusion: Heat polymerizing resin and bisacrylics may be considered in a long term provisional fixed prosthesis.
