Popis: Abstract Objectives Magnetron sputtering was evaluated to equip surfaces of orthodontic elastomeric ligatures with silver and bismuth nanofilms. Material and Methods Antibacterial properties were evaluated by the adhesion of Streptococcus mutans. Polyurethane‐based elastomeric ligatures were coated with silver and bismuth nanofilms via direct current magnetron sputtering. Surface roughness (Ra) and surface‐free energy (SFE) were assessed. Coated specimens were incubated with S. mutans for 2 h. Adhering bacteria were visualized by Hoechst staining and quantified by an ATP‐based luminescence assay. One‐way analysis of variance with Tukey post hoc testing and Pearson correlation analysis were performed (p
