  1. HRW, horizontal ridge width; HRW 0 and HRW 1, immediately before and after bone augmentation surgery; HRW 2 and HRW 3, the 4th and 19th month post-bone augmentation surgery; GR, graft resorption. Within-group comparisons (paired t-test): HRW gain = HRW 2–HRW 0, p < 0.0001; graft resorption at the 4th month (GR1) = HRW 1–HRW 2, p < 0.001; graft resorption at the 19th month (GR2) = HRW 1–HRW 3, p < 0.0001
