Effect of Different Shading Techniques on the Color of Zirconia Ceramic Restoration (An In vivo Study)

BACKGROUND: The color of all ceramic restorations has a significant effect on the final appearance restoration. AIM: This study aimed to evaluate different shading techniques stability monolithic zirconia crowns cemented upper anterior teeth. METHODS: In this study, there were nine patients. Each patient undergone reduction for six Fifty-four jacket constructed using CAD/CAM technique. According technique, categorized into two groups (pre-shaded and liquid shaded), where right reduced teeth received pre-shaded while left liquid-shaded according selected shade. was assessed easy shade after cementation 1 year follow-up period. Data collected, tabulated, statistically analyzed. RESULTS: Color change (ΔE) central incisors, lateral canines 2.37, 2.84, 1.92, respectively, 2.52, 2.88, 2.77, respectively. both within clinically acceptable range 1>E>3.7, no difference between them. CONCLUSIONS: aging technique had ceramic.
