Estimation of Fatigue Deformation for Polyetheretherketone (PEEK) and Cast Cobalt-Chromium Circumferential Clasps: A comparative study
Aims: This in-vitro study aimed to compare the fatigue deformation of Polyetheretherketone (PEEK) and Cobalt-Chromium (Co-Cr) voodoo one 2019 clasps by mechanical cycling test simulating ten years of use.Materials and Methods: 72 clasps samples were fabricated on a standardized e-max upper right first premolar; it is divided into 24 Co-Cr clasps, a
