Purpose: This study aimed to assess the fracture load of anterior crowns fabricated from ceramic–polymer hybrid blocks and lithium disilicate ceramic blocks, both designed for computer-aided design/computer-aided manufacturing wet milling applications. Methods: For fracture load testing, ceramic crown samples were fabricated using lithium disilicate ceramic blocks and ceramic–polymer hybrid blocks (N=15). The ceramic crowns, designed and milled for an abutment manufactured via metal 3D printing, were positioned onto a prepared maxillary right central incisor model (Nissin Dental). The fracture load of the samples was measured using a universal testing machine, and the fracture patterns were examined with a scanning electron microscope (JSM-6701F, Jeol). Differences in fracture load between the two ceramic block types were evaluated using an independent sample t-test (α=0.05). Results: The ceramic–polymer hybrid and all-ceramic materials showed statistically comparable fracture loads (p>0.05). Conclusion: On the basis of the mechanical property evaluations, we can conclude that ceramic– polymer hybrid materials meet clinical standards for use as restorative materials.
