Which of the following steps is NOT involved in bonding zirconia-based ceramics with resin cement?

The correct answer indicates that the step of priming and bonding for light-cured resin cements with a silane agent is not commonly a part of the bonding procedure for zirconia-based ceramics with resin cement.

In the context of bonding zirconia, the primary focus is on creating a suitable surface for adhesion. A key aspect of this process involves surface treatments like air-particle abrasion and tribochemical silica coating, which enhance the surface roughness and increase the bonding area. These treatments make it easier for the resin cement to adhere effectively to the zirconia surface.

The use of a silane coupling agent is significant as it promotes chemical bonding between the silica-coated surface and the resin cement, providing a strong bond. However, traditional bonding agents like those used with silane may not be optimal for direct application on zirconia, which has a different surface chemistry compared to other types of ceramics.

Thus, while steps involving air-particle abrasion and silica coating are critical for enhancing adhesion in zirconia ceramics, the typical bonding process does not primarily focus on the application of a prime/bond system in the same way as it would for other materials. This distinction underscores the specific approach needed for zirconia compared to other ceramic materials, reinforcing the idea that the bonding
