Abstract
The restoration of endodontically treated teeth has evolved in the last two decades from an empirical approach to the application of biomechanical concepts based on scientific evidence. Within this context, the preservation of tooth structure, the presence of the splint effect, and the use of adhesive materials for cementation are among the most important requirements for the long-term success of this type of restoration. The posts are used for the restoration of teeth with large losses at the coronal level, they are also indicated as root reinforcement due to their biomechanical properties that allow the distribution of forces in an apical direction and increase dental resistance. There are different alternatives and materials for cementing, resin composites are generally superior to conventional cements as they provide greater strength, less wear on the cement and better aesthetics. OBJECTIVE: To determine the tensile strength and compressive forces of two cementing agents in teeth with intra-root retainer in Base metal through a bibliographic review. RESULTS: It was determined that Relyx U200 cement shows better properties than Ionomero Glass cement, is more resistant to traction, has better behavior against fractures, has a significant advantage over glass ionomer in terms of retention and resistance to forces compressive. CONCLUSION: According to the literature review, it is inferred that Relyx U200 cement presents excellent properties of fixation, adhesion and resistance, in terms of tensile and compression forces; It is more resistant and had a better behavior in the tests carried out, even better reaction than the Glass Ionomer.
