Due to the fundamental view in dentistry concerning maximally conservative preparation hard dental tissues, indirect restorations, fabricated extraorally such as veneers or inlays, onlays, overlays, are becoming increasingly popular. The factor that largely determines the long-term durability of these restorations is the choice of suitable materials and appropriate cementing procedure. Composite materials used for filling cavities, have no application for the cementing procedure but reports in literature indicate when these materials are heated they gain new properties, in which makes them perfectly suitable for cementing permanent prosthetic restorations. Pre-heating of composite material increases its fluidity, microhardness, elastic module and reduces the viscosity of the material, which facilitates its application. The degree of monomer conversion increases significantly with the increase of the composite resin temperature Pre-heated composite can be used for cementation of veneers and restorations such as inlays, onlays, overlays, both composite and ceramic ones. Summing up, increasing the temperature of the composite material increases the degree of conversion, microhardness, tensile strength and elastic module at the same time decreasing viscosity. In addition, pre-heating of the composite material does not adversely affect the stability and opacity of the colour. However, there are few reports comparing the quality of the pre-heated composite material with that of dual composite cements that are currently widely used for the cementation of prosthetic restorations.
