Abstract
Purpose: The purpose of this study was to compare the shear bond strength of the metal-heat pressed glass ceramic bilayer structure.
Methods: Metal framework specimens were prepared and surface is spreaded opaque(IPS InLine system opaque, IvoclarVivadent, Liechtenstein). There were 10 specimens for each bilayer dental ceramic group. The first group was porcelain fused metal, Press on metal IPS Inline press group, and press on metal HASS prototype group. Specimens measured for the shear bond strength on Schwickerath test by Instron universal testing machine(Instron3345, Instron Corp., USA). Mean average bond strength values of each specimen group were analyzed using a one-way ANOVA analysis of variance Saphiro-wilk’s test. Statistical analysis were performed using IBM SPSS 23.0(IBM Co., Armonk, USA)
Results: RMS±SD The highest mean average HASS POM showed a bond strength value (47.55± 12.80 Mpa). The lowest mean average values Porcelain fused metal (33.30 ± 2.00 Mpa). Independent t-test was conduct to analysis the significant difference (p<0.05) (Table 3).
Conclusion: Three kinds of Metal/ glass bilayer dental ceramics bond strength were clinical acceptability. Especially, as
lithium disilicate containing represents higher bond strength.
