In the Cox models, “maximum occlusal force” had a significant effect for implant loss (<i>p</i> = 0.038) and for prosthetic screw loosening (<i>p</i> = 0.038); “arch” and “bruxism” were not significant. Peri-implant bone loss was 0.4 ± 0.6 mm at 10 years. For peri-implant bone level, “crown-to-implant ratio” (<i>p</i> &lt; 0.001) and “time” (<i>p</i> = 0.001) were significant.
