Effect of active application of self-etching ceramic primer on the long-term bond strength of different dental CAD/CAM materials

Background The objective of this in vitro study was to evaluate the effect of the active application of self-etching ceramic primer (MEP however, after aging the bond strength value was significantly reduced. HC showed reduced bond strength values regardless the ME&P application. Conclusions In order to obtain a durable bond strength, the recommended protocol of 20 s of active application followed by 40 s of sitting time in the self-etching ceramic primer should be followed when using reinforced-glass ceramics as restorative materials.
