Scanning electron microscopy images of the LAPA/SBF-3-0017 sample. (a)—Vascular structure, in which it is possible to observe the intense precipitation of calcite crystals. (b)—Well-developed calcite crystals on the surface of the bone structure. (c, d)—Bone surface with precipitated calcite crystals that are partially covered by terrigenous material.
