Abstract
This study aimed to compare the mechanical
behavior of circumferential and RPI clasps manufactured in cobalt–chromium
(Co-Cr) and polyether ether ketone (PEEK) using three-dimensional finite
element analysis (FEA). A 2×2 factorial in silico design was applied with four
experimental groups (n=16 models). Dislodgement forces, von Mises stresses, and
retentive tip displacement were evaluated. Co-Cr clasps showed higher stress
concentration and lower displacement, while PEEK clasps exhibited lower
stresses with greater elastic deformation. These findings suggest that PEEK is
a viable alternative material for removable partial denture clasps in clinical
situations requiring reduced stress transmission to abutment teeth.
