Between 2015 and 2018, a total of 105 implants were placed in 105 patients over a follow\u2010up period of 5\u20138\u2009years. Implant failures and endo\u2010sinus bone gain (ESBG) were assessed. Statistical models were established to investigate the potential influencing factors of implant survival and ESBG.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Six patients with six implants were lost, resulting in cumulative survival rates of 94% for both patient\u2010 and implant\u2010based analyses. The 8\u2010year cumulative survival rate was significantly lower for residual bone height (RBH)\u2009&lt;\u20094\u2009mm (88%) compared to RBH 4\u20136\u2009mm (98%). ESBG \u2265\u20094\u2009mm and ESBG \u2265\u20096\u2009mm were observed in 89.90% and 58.59% of implant sites, respectively. According to the log\u2010rank Mantel\u2010Cox analysis results, none of the factors examined were significantly related to implant failure, except for RBH (<jats:italic>p<\/jats:italic>\u2009=\u20090.038) at baseline. The linear mixed\u2010model regression results showed that the final ESBG was positively correlated with implant insertion site (<jats:italic>p<\/jats:italic>\u2009=\u20090.003), implant length (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001), sinus floor elevation (SFE) methods (<jats:italic>p<\/jats:italic>\u2009=\u20090.010), and RBH (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Within the limitations of this study, it has been established that TSFE with grafting was a reliable method for implant placement in the posterior atrophic maxilla ridges with RBH ranging from 4 to 6\u2009mm.
