Influence of cement shade, ceramic thickness, and airborne-particle abrasion of titanium surface on the final color of monolithic lithium disilicate glass-ceramic hybrid-abutment systems in vitro.

The color measurements were performed with a clinical spectrophotometer. The mean and standard deviation of evaluated AE values were calculated. A three-way analysis of variance (ANOVA) was used for analyzing the data. Statistical analyses were computed with a sig-nificance level of alpha = .05 using a statistical software program (Minitab 17, Minitab). Results:The 0.5-and 1-mm-thick ceramic specimens cemented with Panavia V5 Opaque showed the lowest AE values when cemented on both non-airborne-particle-abraded (5.62 +/- 1.66, 3.15 +/- 1.28) and airborne-particle-abraded (5.55 +/- 0.86, 3.16 +/- 0.49) surfaces, while the highest values were seen in the groups cemented with RelyX U200 A2 (29.22 +/- 0.83, 17.23 +/- 0.45) and Panavia V5 A2 (29.94 +/- 1.17, 16.71 +/- 0.44) on airborne -particle-abraded surfaces. For the 1.5-mm-thick ceramics, the lowest AE values were seen when Multilink MO 0 cement was used on non-airborne -particle-abraded surfaces (1.56 +/- 0.29) and when Panavia V5 Opaque was used on airborne-particle-abraded surfaces (1.56 +/- 0.66). The highest values were seen when RelyX U200 A2 (9.77 +/- 1.13), PA2 (9.24 +/- 0.25), and Multilink HO 0 (9.19 +/- 1.33) were used on airborne-particle-abraded surfaces, and when Multilink HO 0 (9.61 +/- 1.70) was used on non-airborne -parti-cle-abraded surfaces. The 1-mm-thick ceramics cemented with Multilink HO 0 showed higher AE values (12.05 +/- 1.99) for airborne- particle-abraded and non-airborne-particle-abraded (12.58 +/- 1.06) than thinner (0.5 mm) or thicker (1.5 mm) ceramics. Conclusion: Thinnest ceramic superstructures resulted in the highest AE val-ues. Cements that mask the underlying color reflect their own shade under thin superstructures. Airborne-particle abrasion of titanium surfaces increases the grayish reflectance if cement shade does not have the color masking ability.eninfo:eu-repo/semantics/closedAccessAdhesive CementAirborne -Particle AbrasionColorCustom AbutmentTitanium BaseArticle538678688WOS:0008779495000042-s2.0-85136909717Q410.3290/j.qi.b3045089Q2
