Influence of the Angle of Cervical Convergence on Stresses to the PDL of Abutments: A 3D Analysis Using Finite Element Method
Objective: This study was designed to compare the stress produced at the PDL of abutment 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...

| Summary: | Objective: This study was designed to compare the stress produced at the PDL of abutment 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 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. |
