Statistically significant compared to BCP; for intergroup comparisons of and , , and and , Kruskal-Wallis test and post hoc Mann–Whitney test using Bonferroni correction () were used. For the rest of intergroup comparisons, one-way ANOVA with post hoc Dunnett’s test was used (); W, the region adjacent to bony window; C, the center of the augmentation; M, the region adjacent to Schneiderian membrane; NB, new bone area; RM, residual graft material area; NM, nonmineralized tissue area.
