Schematic drawing and pictures of the surface modification. A) The three investigated surfaces were smooth titanium (CTRL), the modification of the titanium surface with the amphora-shaped pores and the silver deposition (* blue dots) in the titanium oxide layer (Porous), and the porous surface loaded with gentamicin (# yellow) (Genta). B) The macroscopic changes of the wire due to the laser treatment. C) The tips of the K-wires without and with laser treatment; the porous structure of the modified surface is clearly visible.
