Abstract
Endodontically treated teeth remain highly susceptible to fracture due to significant loss of structural integrity and optimal restorative material selection remains a clinical challenge. Therefore, it is of interest to evaluate fracture resistance, marginal adaptation and microleakage of fiber-reinforced composite (FRC) restorations compared with conventional composite and metal-ceramic crowns under simulated functional loading. Ninety extracted human premolars were randomly assigned to three groups and subjected to cyclic loading (200 N, 500,000 cycles) using a chewing simulator. FRC restorations demonstrated significantly higher fracture resistance (987.4 ± 62.3 N) compared to conventional composite (743.2 ± 58.1 N) and showed comparable marginal adaptation to metal-ceramic crowns (p<0.001). Fiber-reinforced composites may provide a biomechanically superior and clinically viable alternative for restoring endodontically treated teeth, particularly in high load-bearing posterior regions.
