Comparative study in vivo of the osseointegration of 3D-printed and plasma-coated titanium implants

Figure 2 Fluorescence microscopy of rat femoral sections after index surgery. Titanium implants (black color) with 3D-printed or plasma-coated titanium in the distal metaphysis of the rat femur. Bone trabeculae are formed along the perimeter of implants with areas of bone marrow. White rectangles show fragments of the corresponding photos taken at a higher magnification. Longitudinal sections. A-D: 45 d (n = 10) after implantation; E-H: 90 d (n = 10). B: Bone trabeculae; Bm: Bone marrow.
