Surface Modifications of Dental Ceramic Implants with Different Glass Solder Matrices: In Vitro Analyses with Human Primary Osteoblasts and Epithelial Cells

Figure 5

Left: metabolic activity of the gingival epithelial cell line Ca9-22 cultured for 96 hours on specimens with different surface properties. Values are means ± SD (). Statistical significance levels ( ≤ 0.05; ≤ 0.01; ) compared to titanium () and between the native and the modified ceramics (∘). Right: Live/dead staining of Ca9-22 cells cultured on (a) native titanium, (b) native ATZ ceramic, (c) ATZ with glass solder matrix S1, and (d) ATZ with glass solder matrix S2. Living cells are displayed in green and dead ones in red. Scale bar: 50 μm.
