The rehabilitation of an edentulous maxilla always presents a great challenge due to the anatomical changes that occur during the teeth absence. The clinical options available for this rehabilitation are muco-supported dentures, dentures retained by dental implants or full-arch fixed rehabilitations supported by dental implants. In this paper it is presented the biomechanical analysis of a removable complete denture retained by four implants, in which one of them did not allow a straight abutment because of its angulation. In order to do a biomechanical analysis, the finite element method was chosen to localize the critical points of the stress distribution. This analysis revealed that stresses are higher in the angulated implant and its surrounding cortical bone, than in the straight implants, which must be considered when planning this oral rehabilitation.
