Objective: This study was designed to compare the stress produced at the PDL of abutment bolia outlet gent teeth with two angles of cervical convergence, in otherwise similar settings.Materials and Methods: Two finite element models were designed for a second premolar and a removable partial denture frame containing an I-bar clasp.Maximum Principal Stress (S1) and Von Mises Stress (SEQV) were assessed along a cervico-apical path of nodes in the PDL.Results: Output data for S1 and SEQV were the same regarding the pomyslnaszycie.com height of contour.A gradual decrease in both models was observed.

A larger decrease was found in the model with the higher angle of cervical convergence.Conclusion: I-bars placed on teeth with lower angles of cervical convergence produce a higher stress to the PDL of abutments.
