FIBER POST VS METALLIC POST

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 optical properties compatible with all-ceramic restorations. While metallic posts remain advantageous in high-load posterior situations fiber posts are particularly indicated in anterior and esthetically demanding cases aligning with contemporary biomimetic principles that emphasize tooth preservation and repair-friendly failure modes.
