Do preheated composite resins provide better cementation results for indirect restorations? A Systematic Review

Background: The article addresses the use of preheated composite resins as cementation agents in indirect restorations, highlighting the importance of these materials in the adhesion between the restoration and the dental substrate. Cementation agents are crucial for the overall strength of restorations, and research indicates that resins with higher inorganic filler content may enhance the strength of ceramic restorations. Material and Methods: The study was conducted as a systematic review, following PRISMA guidelines, and analyzed bond strength, physicochemical properties, and color variations. After a search in various databases, nine studies were included in the analysis. Results: The results suggest that while preheated composites may have some advantages, their mechanical properties and the thickness of the cementation layer are not superior to those of traditional resin cements. Conclusions: The article concludes that the adoption of these composites as cementation agents results in modest improvements, and caution is needed when considering their clinical application.
