Effect of different polishing protocols and repolishing on the stainability of a 3D printed resin after immersion in coffee.

Description :

3D printed composite restorations offer efficiency but are prone to staining, affecting aesthetics. Effective finishing and polishing are crucial for surface smoothness and texture, influencing light reflection and gloss. However, choosing appropriate protocols is challenging, considering material properties and clinical effectiveness. Staining can be exacerbated by surface roughness, highlighting the need for optimal polishing techniques. While repolishing has shown promise in mitigating stains on other materials, its efficacy on 3D printed resin remains unclear. This study aims to evaluate the effect of polishing on color stability and the potential of repolishing in stain reduction for 3D printed composite restorations. Results will guide clinicians in enhancing aesthetic outcomes and patient satisfaction
