Effect of denture cleansers and surface treatments on the color stability, gloss, and wettability of CAD‐CAM denture bases

Renew produced the greatest overall changes in color and wettability. Gloss changes were strongly material‑ and treatment‑dependent. Optiglaze‑coated 3D‑printed and compression-molded bases immersed in Val-Clean showed pronounced gloss loss. Polished surfaces generally retained gloss better. Compression-molded materials were more susceptible to color change than milled or 3D-printed materials, and the Optiglaze did not consistently reduce changes in color, gloss, or wettability. These findings may inform future research and the development of evidence-based denture-cleaning protocols; however, clinical studies are needed before specific recommendations can be made.
