Abstract:
PURPOSE:. The aim of the study was to evaluate the optical properties of new generation (3Y-TZP) monolithic zirconia (MZ) with different abutment types and resin cement shades.
MATERIALS AND METHODS:. A1/LT MZ specimens were prepared (10 × 12 × 1 mm, N = 30) and divided into 3 groups according to cement shades as transparent (Tr), yellow (Y) and opaque (O). Abutment specimens were obtained from 4 different materials including zirconia (Group Z), hybrid (Group H), titanium (Group T) and anodized yellow titanium (Group AT). MZ and abutment specimens were then cemented. L*, a*, and b* parameters were obtained from MZ, MZ + abutment, and MZ + abutment + cement. ∆E001 * (between MZ and MZ + abutment), ∆E002 * (between MZ and MZ + abutment + cement) and ∆E003 * (between MZ + abutment and MZ + abutment + cement) values were calculated.Statistical analyses included 2-way ANOVA, Bonferroni, and Paired Sample t-Tests (P < .05).
RESULTS:. Abutment types and resin cements had significant effect on L*, a*, b*, ∆E001 *, ∆E002 *, and ∆E003 * values (P < .001). Without cementation, whereas zirconia abutment resulted in the least discoloration (∆E001 * = 0.68), titanium abutment caused the most discoloration (∆E001 * = 4.99). The least ∆E002 * = 0.68 value was seen using zirconia abutment after cementation with yellow shaded cement. Opaque shaded cement caused the most color change (∆E003 * = 5.24). Cement application increased the L* values in all groups.
CONCLUSION:. The least color change with/without cement was observed in crown configurations created with zirconia abutments. Zirconia and hybrid abutments produced significantly lower ∆E002 * and ∆E003 * values in combination with yellow shaded cement. The usage of opaque shaded cement in titanium/anodized titanium groups may enable the clinically unacceptable ∆E00 * value to reach the acceptable level.[J Adv Prosthodont 2023;15:114-25]
