ABSTRACT IN VITRO COMPARISON OF COLOR STABILITY OF 3D-PRINTED HYBRID CERAMIC CROWN MATERIALS AMONG DIFFERENT BRANDS Abdulaziz Alshuwaier, BDS Marquette University, 2026 Aim: The primary aim of this study was to evaluate and compare the color stability of three commercially available 3D-printed permanent hybrid ceramic crown materials, SprintRay® Ceramic Crown, VarseoSmile® Crown Plus, and Rodin Sculpture™, following exposure to common dietary staining solutions. The influence of immersion media and time on color change was assessed using spectrophotometric readings. Materials and Methods: A total 45 of disc-shaped specimens (10 mm x 2 mm) were fabricated in shade A1 from three materials: Rodin Sculpture™, VarseoSmile® Crown Plus, And SprintRay® Ceramic Crown (n = 15 per material). Specimens were finished, polished, and immersed in distilled water (control), coffee, or red wine at 37°C. Color measurments were obtained using a Konica Minolta CM-700d spectrophotometer at baseline (Day 0), Day 7 and Day30 under both specular component included (SCI) and specular component excluded (SCE) modes. Color changes were calculated using the CIEDE2000 (ΔE₀₀) formula. Repeated- measures ANOVA and pairwise t-test were used to evaluate the effects of immersion solutions, time, and material type. Results: Distilled water produced minimal color change for all the materials, while coffee and red wine resulted in significantly greater discoloration over time. Red wine produced the highest ΔE₀₀ values across all the materials, followed by coffee. Color increased progressively from day 7 to day 30. Rodin SculptureTM exhibited the highest susceptibility to staining, particularly in red wine, while SprintRay® Ceramic Crown demonstrated comparatively better color stability. VarseoSmile® Crown Plus showed intermediate performance. Baseline inter material color differences were also observed despite identical shade designation (A1), indicating variations in optical properties among the materials. Conclusion: Within the limitations of this study, immersion media, material composition, and exposure time significantly influenced the color stability of 3D-printed hybrid ceramic crown materials. Red wine and coffee showed greater discoloration compared with distilled water, with Rodin SculptureTM showing the greatest staining susceptibility. These findings suggest that material selection may influence long term esthetic outcomes of 3D-printed permanent restorations, particularly in patients with frequent consumption of chromogenic beverages.
