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.
