| Summary: | In this chapter, the data for equivalent von Mises stress (EQV) and resultant displacement generated within bones and prosthetic components are presented and discussed for both intrasinus and extramaxillary approaches in different occlusal loading directions. There are four different occlusal loading inclinations have been considered, 0 (L3a), 15 (L3b), 30 (L3c) and 45° (L3d), respected to the standard implant axis. The results of analysis have also been compared with the EQV and resultant displacement data obtained by the vertical occlusal loading (L3), at similar loading location. Results showed that the oblique occlusal loading with horizontal components produced higher magnitude of stress or displacement than the pure vertical loading. The bones and prosthetic components exhibited higher stress magnitude for the intrasinus approach compared to the extramaxillary under almost all loading inclinations. However, the results of displacement showed otherwise where the framework and implants in the extramaxillary generated higher displacement values than those in the intrasinus. |
