Figure 1: (a) Photo of control conical implant (Ø = 2 mm, l = 6 mm). (b, c) SEM images of control surface. (d) Photo of dual-stemmed (SIT) implant (Ø = 3 mm, l = 6 mm). (e, f) SEM images of SIT implant surface. At higher magnification, it is clear that the 3D printed surface (f) retains characteristic surface features representative of the powders used in its production and has a much higher roughness than conventionally machined implants (c).
