Objective.
To assess fracture resistance and failure mode of repaired fiber-reinforced composite (FRC) cusp-replacing restorations.
Methods.
Sixteen extracted human premolars with fractured cusp-replacing woven (Group (A)) or unidirectional (Group (B)) FRC restorations from a previous loading experiment were repaired with resin composite and loaded to fracture.
Results.
Differences in fracture loads between groups were not statistically significant (P = 0.34).
Fracture loads of repaired specimens were significantly lower than those of original specimens (P = 0.02 for Group (A) and P < 0.001 for Group (B)).
Majority of specimens showed failure along the repaired surface.
In Group (B) 89% of specimens showed intact tooth substrate after restoration fracture, while this was 28% in Group (A) (P = 0.04).
Conclusion.
Fractured cusp-replacing FRC restorations that are repaired with resin composite show about half of fracture resistance of original restorations.
Mode of failure with a base of unidirectional fibers is predominantly adhesive.
