Metallic posts, whether cast or prefabricated, have long been employed for the restoration of endodontically treated teeth owing to their high strength and longevity; however, their elevated elastic modulus compared with dentin predisposes to unfavorable stress concentration, vertical root fractures, compromised esthetics, and difficulty of retrieval. Fiber-reinforced composite posts, composed of glass or quartz fibers in a resin matrix, exhibit an elastic modulus comparable to dentin, thereby promoting more favorable stress distribution, reducing catastrophic failures, and offering superior...
