Evaluation of Stress Distribution in Implant-Supported Restoration Under Different Simulated Loads

Technical and scientific developments, in the form of osseointegrated implants, have made Restorative Dentistry evolve to become a highly successful form of treatment (Adell et al., 1981; Binon, 2000), considered as an additional safe tool oral surgeons have at their disposal to rehabilitate partially and totally edentulous patients. However, many negative factors can interfere in the treatment, causing clinical and functional complications that may culminate in the loss of osseointegration (Adell et al., 1981; Jemt et al., 1989; Naert et al., 2001a, 2001b; Isidor, 2006). The attachment of the crown to the abutment and of the latter to the implant, the loosening of the fixation screw, and even its fracture may arise from a poor distribution of occlusal loads in the prosthesis-implant set (Binon, 1994).
