The aim of the present project is to evaluate functional, biological and technical variables, as well as quality of life and satisfaction as indicators of long-term clinical performance of single prostheses on short implants in the posterior region with a 10-year prospective follow-up. This proposal refers to a clinical research project with a 10-year follow-up of single crowns on short implants (6 mm) in the posterior region of the maxilla and mandible. The cohort has started in 2010 through a project funded by the International Team for Implantology. The main clinical results with a 4-year follow-up showed the influence of biomechanical factors (implant/crown ratio) on short-term treatment success and increased risk over time. The sample will consist of participants from the cohort of the research project established in 2010, who received a single crown on a short implant (6-mm Standard Plus Wide Neck SLA) in the posterior region of the maxilla or mandible according to eligibility criteria and standardized clinical procedures. Data will be collected by clinical and image exams, questionnaires (for sleep bruxism, satisfaction and quality of life), recording of maximum occlusal force, measurement of perimplant bone changes, and calculation of the clinical crown-implant ratio. Data will be analyzed by descriptive and inferential statistics with survival analysis and multivariable models, if assumptions are met, at the significance level of 0.05.
