Endodontically treated teeth (ETT) are highly vulnerable to fracture due to loss of marginal ridges and reduced structural integrity. Posts are often used to retain coronal build-up material, but they do not reinforce roots and may weaken them by removing radicular dentin during preparation. Traditional cast metal posts, though widely accepted, have been linked to catastrophic root fractures. To overcome biomechanical and esthetic limitations, fiber-reinforced posts were introduced, offering elasticity similar to dentin and improved esthetics. Glass and quartz fiber posts further enhanced outcomes, though stress concentration at the cervical region remains a challenge. Modern restorative concepts emphasize posts that balance retention, esthetics, and retrievability, with functionally graded composite posts proposed to vary elasticity along their length for optimal performance. The Edelweiss post and core system represents a step toward a single-unit solution, reducing chairside time while ensuring biological, biomechanical, and bioesthetic success in restoring compromised ETT.
