This study aimed to evaluate the long-term outcomes (up to 10 years) of two prospective cohorts of completely edentulous individuals treated with single implant mandibular overdenture (SIMO) opposed to a conventional maxillary complete denture. A total of 74 participants, treated between 2013 and 2016 at the School of Dentistry of the Federal University of Goiás, Brazil, were included. A single implant was placed in the mandibular midline, followed by the creation of a relief space in the complete mandibular denture, utilizing the ball O-ring retention system (Neodent, Curitiba, Paraná, Brazil), outcomes were followed for 8 -10 years. Data collected included patient satisfaction with the dentures, quality of life related to oral health through the Oral Health Impact Profile for the Edentulous (OHIP-Edent), implant survival, implant stability, peri-implant health, and incidence of prosthodontic events. Multiple regression was performed using a Generalized Linear Model due to the repeated measurements of the longitudinal data and within-implant peri-implant measures. A significance level of p<0.05 was used. Of the 74 patients, 39 were included in the 8-to-10-year follow-up. Significant improvements in OHIP-Edent scores and satisfaction were observed immediately after treatment and maintained throughout the follow-up period. Regression analyses confirmed a significant positive effect of a SIMO on these outcomes (p < 0.001). The peri-implant results indicated a favorable health status with minimal peri-implant bone changes. The most frequently observed prosthetic complication was overdenture fracture (n = 74). Additionally, the most recurrent maintenance event was matrix replacement (n = 259). SIMO demonstrated good long-term performance with minimal clinical monitoring and maintenance. The initial positive outcomes persisted for up to 10 years, suggesting that a SIMO is a low-complexity option, particularly beneficial for older patients with financial constraints
