Abstract

Introduction: Till a prosthodontist provides the patient with a definitive restoration, he/she should be given a provisional restorative materials. These materials should be biologically, mechanically and esthetically compatible and useful to the patient. Some physical and mechanical properties of these provisional restorations are of extreme importance, like flexural strength, hardness, wear resistance. The importance is to withstand the environment of the oral cavity. So, in this study, we have done this in-vitro study to compare and evaluate the hardness of four of the provisional restorative materials available commercially.
Materials and Methods: 10 samples each of four commercially available provisional restoration materials namely Integrity, Protemp 4, Systemp B and C and Structure 2SC were made and VHN was checked to see the hardness and thus wear resistance of these materials.
Results and Conclusion: In the present study, significant difference was not found in the hardness values for Voco and Systemp C and B whereas Protemp 4 shows greater hardness values than the rest three.

Keywords: Hardness, Wear resistance, Provisional restoration.
