Representative images of presence of biofilm deposition within the implant site in group IV by Scanning electron microscopy (SEM) analysis.

Presence of biofilm deposition on the cut ends of the implants (*) within the intercondylar notch (A, scale bar 200 µm), the implant-bone interface in the boxed area (B, scale bar 10 µm), and the opposite edge of the implanted nail (**) within the medullary canal (C, scale bar 100 µm) in the boxed area (D, scale bar 20 µm, small box 10 µm) are shown in group IV.
