Onlays were fabricated using four materials: Gradia Plus, Signum Ceramis, Tescera ATL, and Grandio Bloc. All restorations were cemented using adhesive protocols and subjected to thermocycling (5000\u2009cycles, 5\u00b0C\u201355\u00b0C). Fracture resistance was tested using a universal testing machine. Fracture types were assessed under a stereomicroscope. Selected samples underwent scanning electron microscopy analysis.
