Shear bond strength of resin bonded zirconia and lithium disilicate – effect of surface treatment of ceramics and dentin -

The purpose of the study was to investigate the effect of ceramic surface pretreatment, effect of resin cement and dentin surface roughness on shear bond strength.

Pre-cementation procedures’ effect on dental zirconias with different yttria content -

Several pre-cementation procedures have been advocated to enhance adhesion between zirconia and resin-based cement. There is, however, limited documentation on how these pre-treatments affect the strength of zirconia crowns as most tests are performed on discs or bars.
The aim was to assess the effect of pre-cementation procedures on fracture mode, fracture strength and cement retention on zirconia.
