Implantology has made possible several forms of rehabilitation and has overcome limitations in the treatment of total or partial edentulous patients. The benefit is notorious for the patient because it allows to reestablish aesthetics and function, without disturbing speech, restoring masticatory efficiency and self-esteem. Despite the fact that Implantology has a high rate of acceptance and success, the increase in life expectancy and the popularization of treatment requires research and studies so that the treatments become long-lived and predictable. In this sense, the longitudinal clinical evaluation of the treatments is necessary to indicate the aspects related to the success and failure of the rehabilitation with implants and implant-supported prostheses. In chapter I, complications related to posterior fixed partial dentures implant-supported in external hexagon implants, metalloceramics made on calcinable UClA were evaluated. Clinical analyzes were performed evaluating peri-implant conditions (visible plaque index, gingival bleeding index, keratinized mucosa width, probing depth, probing bleeding, insertion level); prosthetics (contact point, loosening of screw, splinter or fracture of the ceramic); radiographic (bone loss and marginal maladjustment); bite potency exam and quality of life questionnaire. In chapter II, a comparison between metalloceramic prostheses in calcinable UCLA and zirconia prostheses made in CAD / CAM was performed. In this work, we sought to demonstrate the possible clinical, radiographic differences and the satisfaction and quality of life of patients rehabilitated with different methods of making implant-supported rehabilitation. In chapter III, implant-supported rehabilitation was evaluated in several situations (single, partial and total implants) all performed in CAD / CAM with prostheses in monolithic or stratified zirconia. All patients underwent clinical and radiographic evaluations in order to identify possible peri-implant and prosthetic complications. It was concluded that patients rehabilitated with UCLA had a satisfactory survival rate, but the amount of mucositis and peri-implantitis was higher than the zirconia prostheses made in CAD / CAM. Patients rehabilitated with prostheses made in Zirconia by CAD / CAM system also had less loosening of screws, less loss of contact point, less plaque accumulation and less bone loss over time. The prostheses performed in CAD / CAM showed satisfactory results with high predictability and low complication rates.
