Bone-implant contact (BIC) and connective tissue (TC) percentages in experimental groups (HAnano + L-PRF, DAA + L-PRF, HAnano Sham, DAA Sham). Histomorphometric analysis showed no significant differences (Brown-Forsythe and Welch ANOVA, p > 0.05). BIC ranged from 44–63%, while connective tissue surface ranged from 37–56%. Data are presented as mean ± 95% confidence intervals.
