Six material\/manufacturing method combinations were investigated in this study, namely chromium\u2013cobalt (Cr\u2013Co) (prepared using casting, milling, and laser sintering) and titanium, zirconia, and anodized titanium (all prepared using milling); titanium (stock) abutments were used as the control group. Surface roughness of seven specimens from each group was evaluated using atomic force microscopy and scanning electron microscopy. Laser\u2010sintered Cr\u2013Co had the lowest values of <jats:italic>R<\/jats:italic><jats:sub>a<\/jats:sub> (mean \u00b1 SD = 4.8 \u00b1 0.8 \u00a0nm), <jats:italic>R<\/jats:italic><jats:sub>q<\/jats:sub> (mean \u00b1 SD = 7.0 \u00b1 1.2 nm), and <jats:italic>R<\/jats:italic><jats:sub>max<\/jats:sub> (mean \u00b1 SD = 133.5 \u00b1 31.7 nm), whereas milled zirconia had the highest values of <jats:italic>R<\/jats:italic><jats:sub>a<\/jats:sub> (mean \u00b1 SD = 112.9 \u00b1 44.2 nm), <jats:italic>R<\/jats:italic><jats:sub>q<\/jats:sub> (mean \u00b1 SD = 142.8 \u00b1 54.0 nm), and <jats:italic>R<\/jats:italic><jats:sub>max<\/jats:sub> (mean \u00b1 SD = 1,035.7\u00a0\u00b1 350.4 nm). Three specimens from each group were infected with <jats:italic>S. mutans<\/jats:italic> and three with <jats:italic>C. albicans<\/jats:italic>, and microbial counts were evaluated after culture. Colonization of <jats:italic>Streptococcus mutans<\/jats:italic> was highest on milled zirconia (mean log<jats:sub>10<\/jats:sub> count\u00a0\u00b1\u00a0SD\u00a0=\u00a05.87\u00a0\u00b1\u00a00.08) and lowest on milled Cr\u2013Co (mean log<jats:sub>10<\/jats:sub> count\u00a0\u00b1\u00a0SD\u00a0=\u00a04.04\u00a0\u00b1\u00a00.11). For <jats:italic>C. albicans<\/jats:italic>, colonization was highest on milled titanium stock (mean log<jats:sub>10<\/jats:sub> count\u00a0\u00b1\u00a0SD\u00a0=\u00a06.62\u00a0\u00b1\u00a00.03) and lowest on milled anodized titanium (mean log<jats:sub>10<\/jats:sub> count\u00a0\u00b1\u00a0SD\u00a0=\u00a06.13\u00a0\u00b1\u00a00.03).
