  1. Disc I—Inicell, Disc II—SLA, Disc III—non pretreated, Disc IV—machined
  2. 0—non instrumented surface, A—steel, B—PEEK, C—titanium, D—Carbon, E—resin
  3. Ra—arithmetic mean deviation of the profile
  4. Rz—maximum height of profile, Rt—range of assessed profile points of the assessed surface profile
  5. Different bold capitals indicate significant differences (valid only in the same box)
  6. With regard to Disc 2: Roughness parameters were assessed in parallel direction to the processing direction of the machined surface
