Abstract This In-Vitro study compared the biaxial flexural strength between indirect composite and porcelain for veneering a metal substructure. Twenty-six disks cast in nickel chromium alloy were divided equally into two groups and received different treatments for veneering: Indirect composite (SR Nexco paste) was applied on one group of specimens; the control group was veneered using porcelain (IPS Inline). The specimens were tested by apiston on three balls after 2,500 thermocycles between 5{u00BA}C and 55{u00BA}C water baths with a dwell time of 20 seconds. The fractured specimens were evaluated to determine the mode of failure by a scanning electron microscope. The mean biaxial flexural strength values (in MPa) after thermocycling was 482.9 for the indirect composite group and 657.86 for the porcelain group. The metal-ceramic group exhibited significantly higher strength than the indirect composite group. SR Nexco can be considered as a repair material |
