  1. Data were expressed as a mean (standard deviation (SD)).
  2. Ra: arithmetic mean of the departure of the roughness profile from the profile center-line.
  3. a P < 0.01 compared with Oxinium.
  4. b P < 0.01 compared with Co-Cr-Mo.
  5. c P < 0.01 compared with Ti-6Al-4 V.
  6. d P < 0.01 compared with Cp-Ti.
  7. e P < 0.01 compared with SUS316L.
