Basic characteristics of patients and implants were collected from the medical record system and cone\u2010beam computed tomography (CBCT) images. Kaplan\u2013Meier survival curves were applied to estimate cumulative survival rates (CSRs) and Cox proportional hazards regression models were used to detect factors influencing implant survival.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The 6\u2010year and 12\u2010year CSR of implants placed in sites with RBH \u22643\u2009mm were 95.7% (95% confidence interval [CI]: 92.1%\u201399.5%) and 76.6% (95% CI: 58.1%\u2013100%), respectively. Eight patients presented late implant failure.

Specifically, the 10\u2010year CSR of implants in sites with RBH \u22642\u2009mm (53.3%, 95% CI: 27.5%\u2013100%) was dramatically lower than those in sites with RBH &gt;2\u2009mm (92.9%, 95% CI: 81.7%\u2013100%, <jats:italic>p<\/jats:italic>\u2009=\u20090.000).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Implants placed simultaneously with LSFE in sites with RBH \u22643\u2009mm can achieve long\u2010term survival.
