Abstract
Objective: Evaluate and contextualize the stability of Bulk Fill Composite Resins (RCBF) by analyzing the mechanical aspects, their possible advantages and disadvantagens with regard to resistance and contractions. Methods: It was a literature review, with a descriptive and informative approach, where the formulation process took place through searches for scientific literature, in databases, having as descriptors: The importance of Bulk fill composite resin, its stability, use of polymerization and irradiation power. Results: With regard to RCBF, good stability can be seen, presenting advanced material not only in the aesthetic aspect but also in its physical and mechanical form, this fact is prevented by the fact that its matrix presentes monomers with advanced properties, which significantly decrease the polymerization tension, making the monomers more adjustable, thus allowing greater binding and addition of photoinitiators which, being related to camphorquinone, improves the level of conversion of the molecules. Final Considerations: RCBF are suggested for the restoration of posterior dental elements, which indicate a certain color stability, chemical and mechanical strength, however longitudinal studies are necessary to analyze the stability of their properties in the long term.
