Cemented implant crowns or implant\u2010supported fixed dental prostheses were delivered to the patients. Kaplan\u2013Meier implant survival was 89.2% at implant level and 84.1% at patient level. Complication\u2010free survival was 26.0% at patient level and 37.0% at implant level. The average complication\u2010free survival time was 74.6\u00a0months (95% CI: 63.2\u201386.0\u00a0months) at implant level and 69.1\u00a0months (95% CI: 54.8\u201383.4\u00a0months) at patient level.
