Micro-computed tomography analysis was conducted on the peri-implant bone around titanium (Ti) and iron (Fe) interference screws at 3-, 6-, and 12-month post-implantation. Spectral analysis was used to visualize bone density, with red and black indicating lower bone mass and blue and white indicating higher bone mass. Results are presented as column bar plots depicting bone volume fraction (BV/TV), bone density, and Intersection Surface/Tissue Surface ratio—error bars, median, and interquartile range. M month. * indicated P < 0.05.
