Hybrid Ceramic Onlay Restorations: Injectable Resin vs. Dual-Cure Cement

Posted: September 23, 2025
In a recent 18-month randomized clinical trial comparing the clinical performance of indirect hybrid ceramic onlay restorations cemented with injectable resin composite versus dual-cure resin cement, promising insights were revealed. Despite no significant differences in most outcomes between the two groups, dual-cure resin cement exhibited notably higher marginal discoloration at the 18-month mark compared to injectable resin composite. The decline in alpha scores for marginal discoloration within the dual-cure resin cement group from baseline to 18 months was a notable finding, indicating potential long-term esthetic concerns with this traditional cementation approach.

While both cementation methods showed comparable clinical performance overall, the reduced marginal discoloration observed with injectable resin composite presents a noteworthy advantage. This finding suggests that injectable resin composites may offer a viable alternative to dual-cure resin cements for luting indirect restorations, particularly for practitioners prioritizing enhanced esthetic outcomes. The study's statistical analysis, including inter- and intragroup comparisons and survival rates evaluation, provided a comprehensive assessment of the performance of these two cementation materials over an extended period, shedding light on their long-term clinical viability.

Dental professionals may consider incorporating injectable resin composites into their practice for cementing indirect restorations to potentially mitigate issues related to marginal discoloration. This trial underscores the importance of exploring innovative materials and techniques to enhance the longevity and esthetic quality of dental restorations. The findings contribute valuable insights to the ongoing discussion on optimizing cementation protocols for indirect restorations, emphasizing the need for continued research and evaluation of emerging materials to drive advancements in clinical practice.
