To evaluate the fracture resistance of CAD-CAM resin-matrix ceramic anterior crowns cemented with three adhesive resin cements compared with three resin-modified glass ionomer cements.
Ninety milled nanoceramic hybrid crowns representing maxillary central incisors were cemented onto 3D-printed dies across six cement groups (n = 15 per group): three adhesive resin cements (ReMu, RePa, ReUn) and three resin-modified glass ionomer cements (GiLu, GiEv, GiMe).
Specimens were subjected to 10,000 thermocycles (5 to 55 °C) for artificial aging, loaded under compression until fracture, examined using scanning electron microscopy, and analyzed via one-way ANOVA and Tukey HSD (p = 0.001).
Fracture resistance differed significantly across cement categories (p = 0.001), with adhesive resin cements demonstrating higher fracture loads than resin-modified glass ionomer cements.
RelyX Unicem 2 (ReUn) produced the highest fracture resistance, followed by RePa and ReMu, whereas GiEv and GiLu yielded the lowest values.
