Purpose: This study aimed to examine the effect of polishing time on the surface roughness and topography of Co–Cr alloy using a dental auto polishing system. Methods: Specimens were fabricated as five plate-shaped metal castings per group, each measuring 10×10×1 mm. Sandblaster-treated specimens served as controls, whereas others underwent electrolytic polishing for 10 minutes or treatment with Snow Barrel dental prosthetic grinder (DK Mungyo) for 20, 25, or 30 minutes. The surface roughness of the prepared specimens was measured using an atomic force microscope, and their surface topography was examined with a scanning electron microscope. Results: The surface roughness of all experimental specimens was reduced compared with that of the control group, and the roughness values were similar among the experimental specimens. The specimens subjected to 20 minutes of automatic polishing had the lowest surface roughness. Conclusion: These findings indicate that the polishing time of an automatic dental polishing system can affect the surface roughness of Co–Cr alloys and that increasing the polishing duration can effectively reduce it.
