Melt etching outperforms sandblasting -

For stronger and longer lasting dental crowns, a new NIOM study suggests that melt etching is better than sandblasting.

Comparison of sandblasted, ground and melt-etched zirconia crowns regarding adhesion strength to resin cement -

The aim is to compare the adhesion between zirconia and cements attained with melt-etching with potassium hydrogen difluoride, KHF2, with that found when such traditional surface treatments as sandblasting and ceramic stone grinding are employed.

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.

Reason for loosening of ceramic restorations -

The resin cement forms the weakest link for a ceramic restoration. This was found in an investigation of the de-bonding of resin cementation of zirconia or lithium di-silicate ceramic to bovine dentin.

TMA offers valuable insight of materials properties -

Thermomechanical analysis, TMA, can provide valuable information on materials which influence on production conditions for dental restorations that is difficult to obtain by other analytical techniques.
