Histological analysis of osteointegration ability of four groups using Van Gieson staining at 6 weeks (a, b, c, and d) and 12 weeks (e, f, g, and h). BS group (a, e); SC group (b, f); SM group (c, g); SMC group (d, h). (red represents new bone formation (NB), blue indicates fibrous tissue, and black is the metal (Ti)) (scale bar: 100 μm).
