Left side: Test group. The most peculiar feature of the healing pattern was the unusual granular aspect. The granules observed in the trabeculae, seemed like mineralization nuclei (highlighted by blue arrows). These granules were surrounded by active osteoblasts, osteoid tissue, and osteons (toluidine blue, ×30 magnification) Right side: Implant coronal area in test group. No bone resorption was observed. Many mineralization nuclei were present in the most coronal implant area (toluidine blue, ×25 magnification).
