【 摘 要 】

The aim of this study was to determine the pattern of bone remodeling after maxillarysinus lifting in humans by means of fractal dimension (FD) and histomorphometricanalysis. Therefore, the correlation between FD and the histomorphometric findingswas evaluated. Sixteen patients with posterior edentulous maxilla were enrolled inthis study. Maxillary sinus lifting was performed using autogenous bone grafted fromthe mandibular retromolar area. Three direct digital panoramic radiographs wereobtained: before surgery (Group 1), immediately postoperatively (Group 2) and after 6months of healing (Group 3) for FD analysis. Biopsies were taken after 6 months,processed and submitted to histological and histomorphometric analysis. Data wereanalyzed by Shapiro-Wilk test and ANOVA test followed by a Tukey test (a=0.05). Thebone volume fraction of newly trabecular bone (TB) and medullary area (MA) wasmeasured as 62.75%±17.16% and 37.25±17.16%, respectively. Significant difference inFD analysis was measured between Group 1 and Group 3. No significant difference wasfound in the correlation between FD and histomorphometric analysis for TB and MA(p=0.84). In conclusion, all performed analyses were effective in assessing thebone-remodeling pattern in the maxillary sinus, offering complementary informationabout healing and predictable outcomes. There were no correlations between FD andhistomorphometric analysis.
