Application of polishing systems improves surface roughness and gloss in 3D-printed resins, suggesting better clinical outcomes.
Application of two-step and multi-step polishing systems to 3D-printed permanent resin specimens significantly reduces surface roughness while enhancing microhardness and gloss values. While the application of polishing paste after polishing systems did not influence microhardness, it positively affected surface roughness and gloss, thereby potentially enhancing clinical success.
