Abstract:
Objective To investigate the effects of different surface treatments on shear bond strength between diatomite-based dental ceramic and IPS e.max veneering ceramic.Methods Diatomite-based dental ceramic was randomly divided into acid-etched group,sandblasting group and untreated group,and then sintered with IPS e.max veneering ceramic,respectively.Shear bond strength were detected,and the interface microstructures and elemental distribution were observed by scanning electron microscope-energy dispersive spectrometer (SEM-EDS).Results Shear bond strength of acid-etched group was significantly higher than that of untreated group (P＜0.01).SEM observation results showed that the interface of acid-etched group bonded closely.There was no statistical difference of the shear bond strength between the sandblasting group and untreated group (P＞0.05).Conclusions Acid-etched treatment can significantly enhance the bond strength of diatomite-based dental ceramic and IPS e.max veneering ceramic.
