The acetal resin clasps on anterior abutment teeth allow the improvement of the aesthetics of removable partial dentures. The main objective of this study was to obtain the distribution of von Mises equivalent stress and microstrain on acetal resin and cobalt-chromium circumferential clasps. A cobalt-chromium circumferential clasp was scanned by CAD-CAM ZirconzahnR system, exported to SolidworksR and, subsequently, to the ANSYSR Finite Element (FE) code. On the FE mesh generated, unitary loads on different directions were simulated in the distal third of the clasp's retentive arm. The acetal resin clasp displayed higher deformation values than the cobalt-chromium in any direction of the applied load. For the acetal resin clasp, the maximum stress and strain stood in the initial area of the retentive arm. The obtained results suggest an increasing in the volume on the inner side of the initial area of the retentive arm of acetal resin clasp to optimize stress distribution.
