Abstract: Provisional restorative materials are widely used in fixed partial denture prosthodontics. It should provide occlusion while offering aesthetic restoration to the abutment tooth to avoid compromising patient’s social relationship. Extensive prosthetic treatment requires temporary restorations with high mechanical strength for long-term use. When restorations replace several teeth, in a long span, the strength and stability of the prostheses are critical, and fractures may occur,so that fracture strength of temporary restorations is directly related to the flexural strength and the elastic modulus. The purpose of this study is to evaluate and compare flexural strength and elastic modulus of two different provisional restorative materials (Intregrity & Revotek) are tested after storing in artificial saliva for one week, three weeks and one month. Three point flexural tests were carried out in the universal testing machine to calculate the flexural strength and elastic modulus.
Keywords: Provisional restoration, flexural strength, elastic modulus, integrity, revote.
