Crowns in the maxillary first premolar form were cemented to abutments using resin cement (Panavia 2.0 Introkit). Dynamic loading and thermomechanical aging were applied to the specimens (120,000 cycles, 49\u00a0N, 5\u201055\u00b0C). Fracture resistance values were measured in the universal test machine and fracture types were determined. Two\u2010way ANOVA and Tukey test were used for statistical analysis (Jamovi version 2.3.5).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Both the abutment angle and the type of material had a significant effect on fracture resistance (F = 3.295, <jats:italic>p<\/jats:italic>\u00a0&lt;\u00a00.05). The highest fracture resistance was obtained in Group 0\u02da\u2010Zir, and the lowest fracture resistance was obtained in Group 15\u02da\u2010VE. Fracture resistance showed significant differences between Group 0\u02da and Group 15\u02da for the Zir and VE materials, and between Group 0\u02da and Group 25\u02da for VS (<jats:italic>p<\/jats:italic>\u00a0&lt;\u00a00.05); no statistical significance was determined between the other groups (<jats:italic>p<\/jats:italic>&gt;0.05).
