Implant 2 (S_a 1.27 μm ± 0.24) and implant 5 (S_a 1.22 μm ± 0.36) show the highest roughness values (S_a) of all tested implants: Straumann’s pure ceramic implant was blasted and etched and shows the overall highest S_a value in the rough area. Implant 3 (vitaclinical) shows correspondingly lower S_a around 1.05 μm (± 0.17) (Table 3). The lowest S_a value could be found in implant 4, which was only sandblasted due to manufacturer’s specifications. However, the Zeramex implant despite being sandblasted and etched shows the lowest roughness value around 0.73 μm (± 0.95). Nevertheless, Zeramex shows a fine distribution of small pores all over the surface in the SEM sample images. Camlog’s Ceralog shows the highest roughness in the untreated area with 0.61 μm (± 0.03). Figure 6 shows the box plot of the roughness analysis with implant 5 having the widest distribution of measured values.
