Metal dental restorations are considered one of the therapeutic solutions chosen by the dentist and dental technician for the rehabilitation of intercalated edentulousness, due to the mechanical strength of the prosthetic parts and their adaptation to the dental abutments. In order to increase the quality of life of patients, interdisciplinary studies are increasingly being performed on the materials used in dentistry, in an attempt to evaluate as accurately as possible the resistance over time of dental restorations. A Ni-Cr metal alloy dental bridge made for the prosthesis of an edentulousness was studied. The three-dimensional model of the future prosthetic part in STL format was discretized with the 3-matic software © Materialise N.V. Numerical analyzes were performed using ANSYS © SAS IP, Inc. The simulations performed were of the Structural Static type, which involved requests on all the component elements of the prosthetic part to observe it in which areas and at what forces the prosthetic part will undergo changes.
