Improved bonding of zirconia crowns with resin-based cement -

Several pre-cementation procedures advocate enhancing adhesion between zirconia and resin-based cements. There is, however, limited documentation on how these pre-treatments affect the strength of high translucent zirconia.

Residual stress in bench- and furnace-cooled porcelain-fused to zirconia appliances -

A new study of veneered zirconia shows that the magnitude of residual stresses can only be estimated reliably from the manufacturers’ thermal expansion coefficients if the veneered prosthesis is cooled slowly after the final firing.

Thermal induced deflection of a porcelain–zirconia bilayer: Influence of cooling rate -

To determine the thermal expansion of a porcelain (VM9) and tetragonal zirconia (Y-TZP) as well as the deflection upon re-heating and cooling of a bilayer fabricated from these two materials after slow and rapid cooling during initial fabrication.

Debonding mechanism of zirconia and lithium disilicate resin cemented to dentin -

To evaluate debonding mechanism of zirconia and lithium disilicate cemented to dentin mimicking what could occur in a clinical setting. A null hypothesis of no difference in tensile bond strength between groups of zirconia and lithium disilicate cemented with resin cements was also tested.

NIOM scientists develop new etching technique for zirconia ceramics – improves adhesion of resin cements -

NIOM scientists have developed a surface etching technique that improves adhesion between resin cement and zirconia. This new method called Melt Etching is based on melting of fluoride compounds, and can be readily adapted by dental technicians.
