Surface characteristics of the ZrO2 and Ti specimens investigated in this study. (a) FE-SEM images of the surfaces of IM ZrO2 (injection-molded zirconia without surface treatment), IM ZrO2-S (injection-molded zirconia implant with sandblasting surface treatment), Ti-turned (turned titanium implant), and Ti-SLA (SLA titanium implant) at 2000× (left) and 5000× (right) magnifications. Scale bars = 10 μm. (b) CLSM images of surface roughness of implant surfaces (3D views of color-coded height maps with texture overlay). (c) Surface roughness parameters (Sa and Sdr) of the implant surfaces. Data are presented as the means ± SDs (n = 3). *p < 0.05 and **p < 0.01.
