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).

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). Request PDF Translucency of ceramic materials for CEREC CAD/CAM system Objectives To compare translucency of the ceramic materials (CEREC CAD/CAM).
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). 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. In March 2021, Dentsply Sirona introduced CEREC Tessera - a lithium disilicate block that seemingly competes with Ivoclar Vivadent’s IPS e.max CAD. Color coordinate measurements were performed before and after coffee thermocycling. CEREC Tessera blocks achieve exceptional three-way performance through a unique chemistry that incorporates two complementary crystal structures within a. 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. Dentsply Sirona > CEREC Tessera Abutment Block, refer to the chart below for item numbers. 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).
