%X Hybrid ceramics offer a strong combination of ceramics and resin polymers for dental restorations. Choosing the right luting agent is crucial for their longevity and load-bearing ability. This study aimed to examine how different luting agents affect the load-bearing capacity of CAD/CAM milled hybrid ceramic crowns. CAD/CAM VITA Enamic hybrid ceramic blocks were used to create 15 identical crowns, which were divided into 3 groups and cemented with different luting agents: dual-cure resin, light cure resin, and glass ionomer cement (GIC). Pre-prepared polyurethane resin abutments with periodontal ligament simulation were used and mounted on a universal testing machine to measure maximum loads at fracture. Results were compared using ANOVA (p< 0.05). Although there was no statistically significant distinction in the maximum load at fracture between the groups, resin luting gels demonstrated higher loads than glass ionomer. As seen through visual inspection, GIC displayed more catastrophic fractures in the crowns than resin. The impact of luting agent type on CAD/CAM crown fracture loads appears to be minimal. However, evidence suggests that resin may be a more favorable option than GIC.
