Background Colour and Coping Thickness Key to Zirconia Veneer Shade Accuracy: Study
Researchers have found in a new study that background colour had the greatest impact on final shade outcomes of zirconia veneers, followed by coping thickness.
Two predictive formulas were developed by them to estimate colour difference values between restorations and target shades (A2 or A3), aiding in accurate color matching for discoloured teeth and improving clinical aesthetic results. By adjusting zirconia thickness, transparency, and luting cement shade based on these formulas and clinical context, clinicians can minimize shade discrepancies and improve aesthetic results.
This study aimed to derive predictive formulas for the final colour of restorations for discoloured teeth using zirconia veneers. Coping thickness and translucency of zirconia, background colour, and luting cement shade were assessed. Shapiro-Wilk, ANOVA, paired t-tests, independent t-tests, Tukey’s test, and Automatic linear modeling (p < 0.05) were employed to develop a clinically practical method for predicting the colour difference (ΔE) between sample combinations (SCs) and the shade guides. ΔE values were evaluated against perceptibility (PT = 2.6) and acceptability (AT = 5.5) thresholds. Results: Most discoloured teeth could be restored for A2 or A3 target shade.
