![]() However, reduced glazing duration resulted in decreased translucency and BFS of ALDS.ĪLDS may be an appropriate restorative material for those patients with increased coffee consumption considering its color stability and ability to maintain translucency, particularly when glazed by using a conventional porcelain furnace. ZLS had the highest BFS (p ≤ 0.007).ĪLDS had comparable values to those of other materials. ALDS-N had higher BFS values than ALDS-S (p = 0.005), while LDS had similar values to ALDS specimens (p ≥ 0.201). In the CEREC SpeedFire furnace the process even with stains takes just 4.5 minutes. Among tested materials, only LDS had similar RTP values before and after thermocycling (p = 0.865) as the other materials had lower RTP values after thermocycling (p < 0.001). CEREC Tessera restorations require only a short glaze firing. The aesthetics and the efficiency, its just perfect for me. Both before and after thermocycling, LDS had the highest (p ≤ 0.001) and ZLS had the lowest (p < 0.001) RTP values, while ALDS-N had higher RTP than ALDS-S (p ≤ 0.001). CEREC Tessera's special optical properties in terms of light refraction, light transmission and light absorption make the CEREC Tessera the material of choice - especially for high esthetic restorations in the directly visible anterior region. Two-way ANOVA showed the significant effect of material type, coffee thermocycling, and the interaction between these parameters on RTP values (p < 0.001). Statistical analysis was performed by using 1- (ΔE00 and BFS) and 2-way (RTP) ANOVA tests (α = 0.05). Specimens were then subjected to BFS test. ![]() Color differences (ΔE00 ) and relative translucency parameters (RTP) were calculated. CEREC Tessera Order Information CEREC Tessera Blocks (C14, 4 pcs) REF. Color coordinate measurements were performed before and after coffee thermocycling. CEREC Tessera is available as of inLab CAD and CAM SW 20.0.1. ALDS specimens were divided into two subgroups according to glazing procedures (reduced glaze duration, ALDS-S and normal glaze duration, ALDS-N), while LDS and ZLS specimens were crystallized and glazed. To compare the color stability, translucency, and biaxial flexural strength (BFS) of differently glazed advanced lithium disilicate (ALDS) with those of lithium disilicate (LDS) and zirconia-reinforced lithium silicate (ZLS) after coffee thermocycling.įorty disk-shaped specimens were prepared from three lithium silicate based materials (CEREC Tessera, ALDS IPS e.max CAD, LDS Vita Suprinity, ZLS).
