Changes in the fractal dimension of peri-implant trabecular bone after loading: a retrospective study
نویسندگان
چکیده
PURPOSE To assess bony trabecular changes potentially caused by loading stress around dental implants using fractal dimension analysis. METHODS Fractal dimensions were measured in 48 subjects by comparing radiographs taken immediately after prosthesis delivery with those taken 1 year after functional loading. Regions of interest were isolated, and fractal analysis was performed using the box-counting method with Image J 1.42 software. Wilcoxon signed-rank test was used to analyze the difference in fractal dimension before and after implant loading. RESULTS The mean fractal dimension before loading (1.4213±0.0525) increased significantly to 1.4329±0.0479 at 12 months after loading (P<0.05). CONCLUSIONS Fractal dimension analysis might be helpful in detecting changes in peri-implant alveolar trabecular bone patterns in clinical situations.
