Figure 3.

Representative SEM images are shown depicting the range of low and high osseointegration for each surface. A: Plasma-sprayed titanium surface (P) showing 0% osseointegration (intermediate level, posterior quadrant). B: Plasma-sprayed titanium surface (P) showing 46% osseointegration (diaphyseal level, anterior quadrant). C: Plasma-sprayed titanium surface with hydroxyapatite (PHA) coating showing 11% osseointegration (intermediate level, anterior quadrant). D: Plasma-sprayed titanium surface with hydroxyapatite (PHA) coating showing 100% osseointegration (diaphyseal level, anterior quadrant). E: Chemical-textured surface with hydroxyapatite coating (CHA) showing 24% osseointegration (intermediate level, anterior quadrant). F: Chemical-textured surface with hydroxyapatite coating (CHA) showing 97% osseointegration (diaphyseal level, anterior quadrant). The bar represents 1 mm (image resolution = 280 pixels per mm).
