In the 90s, the use of the composite resin as a cementing agent began, which has the following advantages: a margin with a high filler content, ease of cleaning excesses before polymerization, potential to fill any defect in the preparation, improving marginal sealing etc. One of the controversies of this technique is the elevation of the intra-pulp temperature, which, added to the polymerization process, could rise to cause irreversible damage, however, it has been shown that the preheated resin cools rapidly, thanks to the dental tissues that dissipate heat and the elapsed time of bringing the resin from the oven to the mouth. With the heating of the resins, a reduction in their viscosity occurs, allowing less gaps and better marginal adaptation, without affecting the mechanical properties of the composite resins, this occurs due to increased molecular mobility, which optimizes its mechanical properties after polymerization. Regarding the adhesive properties, the resinous cements and the pre-heated resins have been evaluated by fixing the indirect restorations to the dental structure, obtaining with the pre-heated resins favorable results in relation to filtration, adhesive resistance, but in terms of thickness, resinous cement generates a thinner film, however it becomes possible to use pre-heated resin as a cementing agent as a safe technique.
