The purpose of this study was to evaluate the bond strength and the effect of hydrothermal treatment on the flexural strength of ceramic veneered zirconia. Five types of commercially available veneering ceramics (IPS e.max ZirPress: EZ; Cerabien ZR: CZ; Vintage ZR: VZ; Lava Ceramic: LC; ICE Zirkon Ceramic: IZ) and one 3Y-TZP (3%mol Y2O3 - Tetragonal Zirconia Polycrystalline) ceramic were used as experimental materials. The debonding/crack initiation strengths between 3Y-TZP and veneering ceramics were measured according to ISO 9693. Bi-axial flexural test of veneering ceramics and 3-point flexural test of ceramic veneered 3Y-TZP specimens were performed at crosshead speed of 0.5 ㎜/min. The effect of low temperature degradation on the strength of veneering ceramics was evaluated in artificial salavia of 134℃ for 2 hours. The highest debonding/crack initiation strength was observed in the VZ group (38.2±3.4 ㎫) and the lowest value was observed in the CZ group (29.6±3.7 ㎫). Moreover, the VZ group showed the significant differences with IZ group and CZ group (P<0.05). The three point bending strength of 3Y-TZP ceramics showed the lowest value at 250℃. Bi-axial flexural strengths of veneering ceramics reduced after hydrothermal treatment. In addition, the significant differences between dry groups and hydrothermal groups showed in group EZ and group LC (P<0.05). The three point flexural strength of all veneering ceramics on the 3Y-TZP showed the decrease after hydrothermal treatment. Especially, the significant decrease was shown in group EZ and group CZ (P<0.05).
The flexural strength of veneering ceramics for 3Y-TZP deteriorated with hydrothermal degradation.
The flexural strength of veneering ceramics for 3Y-TZP deteriorated with hydrothermal degradation.
