In contrast, Vita Suprinity PC had the highest strength in every aging condition among the glazing group.Ĭlinically Significant: Although all three materials might be suitable for single restorations, caution is needed when choosing material, especially as the rough surface from clinical adjustments may reduce its strength. The fracture toughness for IPS e.max CAD was the highest with 1.97 ± 0.12 MPa.m1/2, CEREC Tessera 0.93 ± 0.05 MPa.m1/2, and Vita Suprinity PC 0.85 ± 0.08 MPa.m1/2.ĬONCLUSIONS: IPS e.max CAD polished outperformed Vita Suprinity PC and CEREC Tessera with respect to flexural strength under different aging conditions. Vickers Hardness was highest for CEREC Tessera with 7.19 ± 0.47 GPa, then Vita Suprinity PC at 7.05 ± 0.73 GPa, followed by IPS e.max CAD 5.79 ± 0.77 GPa. After thermal cycling and fatiguing, there were no significant effects in flexural strength for CEREC Tessera however, there was an increase in flexural strength for IPS e.max CAD and Vita Suprinity PC. 1 This strength allows for a conservative preparation design, with reduced risk of margin chipping. The highest mean flexural strength for static was IPS e.max CAD 385.91 ± 46.23 MPa, then Vita Suprinity PC glazed 355.72 ± 72.44 MPa, followed by CEREC Tessera glazed 323.40 ± 61.01 MPa. CEREC Tessera blocks are the strongest glass ceramic blocks currently offered anywhere in the marketup to 32 stronger than the competition,1 with biaxial strength measured at more than 700 MPa. RESULTS: Significant differences were observed in the mean of biaxial flexural strength between the three glass-ceramics materials. Simple and fast processing fewer steps to get to. For veneers, inlays, onlays and crowns in the anterior and posterior region. Data were analyzed using one-way ANOVA test or least square regression (α = 0.05) and the post hoc Tukey HSD test. CEREC Tessera Advanced Lithium Disilicate CAD/CAM Blocks are made of fully crystallized, high-strength ceramic that can be matrix fired in as little as 4 minutes, 30 seconds when using the CEREC SpeedFire Furnance. Additionally, surface topography and crystal microstructure analysis by SEM and crystallographic structural analysis by X-ray diffraction were done. Also, surface roughness was measured for each group using a stylus contact profilometer. Vickers indentation was performed to test microhardness and fracture toughness. Thermal artificial aging cycling was from 5° to 55☌, while fatigue was used for about 20% of the static failure load for 200,000 cycles.

The biaxial flexural strength test was preformed according to ISO 6872-2015 using an Instron universal testing machine. Specimens were randomly assigned for the biaxial flexural strength test then each group was tested under three conditions post-treatment: (1) static, (2) thermal cycling for 5000 cycles, and (3) cyclic loading at 200,000 cycles. Specimens were divided into three groups (1) glaze control, (2) polish only, and (3) ground after manufacturer glaze. The following case report demonstrates the fabrication of seven monolithic single-tooth restorations by using a novel advanced lithium disilicate (ALD) ceramic (CEREC Tessera, Dentsply Sirona, Charlotte, USA) fabricated with the CEREC system (Primescan and MC X5, Dentsply Sirona, Charlotte, USA) (Figure 1). MATERIALS AND METHODS: For each material, CAD/CAM blocks were sectioned into a total of N=108 (n=12 per group) test discs with a diameter of 11.3 mm core drill and used the precision saw machine.
