Restorations were cemented with resin luting cement (Variolink Esthetic, Ivoclar) to 3D\u2010printed resin dies. Bonded restorations received 5000 thermal cycles and then were loaded until fracture. Statistical analysis included One\u2010Way ANOVA.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Conventional pre\u2010crystallized e.max CAD displayed the highest fracture load value (640 N), followed by fully\u2010crystallized n!ce Straumann (547 N), pre\u2010crystallized Cerec Tessera (503 N), pre\u2010crystallized Amber Mill (476 N), respectively; fully\u2010crystallized GC Initial LiSi Block (431 N) displayed the lowest values. When comparing the fracture load of recent lithium disilicate ceramic material to the e.max group, which acted as the control, significant differences were noted. The LiSi Block GC group, in particular, had considerably higher mean difference values (208.867, <jats:italic>p<\/jats:italic> &lt; 0.001, 95% CI [89.63, 328.10]), as did the Amber Mill group (164.200, <jats:italic>p<\/jats:italic> = 0.002, 95% CI [44.96, 283.44]) and CEREC Tessera group (137.533, <jats:italic>p<\/jats:italic> = 0.016, 95% CI [18.30, 256.77]). The e.max and n!ce Straumann groups had no statistically significant differences in mean scores (92.933, <jats:italic>p<\/jats:italic> = 0.198, 95% CI [\u221226.30, 212.17]).
