| Popis: | Objective To compare displacement resistance of four cementing agents. Material and methods An experimental, cross-sectioned prospective research was conducted to assess four cementing agents. Three agents were resinous, self-adhesive, dual polymerization cements containing MDP (10-metacryloxydecyl dihydrogen phosphate), and the remaining was a conventional glass ionomer cement. In the experiment, 40 samples of zirconia partially stabilized with yttrium were prepared. All samples were treated following their specific manufacturer's instructions. Samples were prepared, they were then stored at 100% humidity in a temperature chamber at 37 oC for 24 hours; after this, samples were subjected to shearing detachment mechanical tests at a 1 mm per minute speed in a universal machine for mechanical testing. Results Glass ionomer samples failed before being taken to the universal testing machine. Remaining three cements did not show statistically significant differences. Conclusions Adhesion capacity of glass ionomer to zirconia is nil or extremely low. Likewise, resinous cements containing MDP in their formula, either in their bonding agent or in the cement formulation itself, are presently the best alternative to increase adhesion to a zirconia structure. |
