Fracture Resistance of Endodontically Treated Premolar Teeth Restored with PEEK Post and Biological Dentin Post: An In Vitro Comparative Study
Polyetheretherketone has a lower Young’s modulus (3–4 GPa)compared to dentin, and it can serve as a shock absorber, lowering the strains placed on the restoration and teeth. For the restoration of teeth that have had endodontic treatment, PEEK posts-and-cores may be a practical substitute.
