What is the correct sequence for luting a porcelain veneer with resin cement?

The correct sequence for luting a porcelain veneer with resin cement involves several key steps to ensure proper bonding and esthetic results. Starting with the try-in paste, the clinician assesses the fit and esthetics of the veneer before proceeding. After this evaluation, it's essential to rinse the veneer thoroughly to remove any residual try-in paste, which can interfere with bonding.

The next step is to etch the porcelain veneer. This process creates a rough surface that enhances the mechanical retention of the resin cement. Following this, a primer is applied to the veneer. The primer is crucial as it promotes adhesion between the etched surface of the porcelain and the resin cement. It typically contains silane, which reacts with the silica in the porcelain to create a strong bond.

Next, the tooth preparation is also etched to further enhance the bond with the resin cement. This dual etching—of both the veneer and the tooth—ensures an optimal bonding surface.

Finally, resin cement is applied to the prepared tooth surface and the veneer, allowing for a strong, durable attachment that also maintains the aesthetic qualities of the veneer.

This multi-step process is vital to achieving a successful veneer placement and ensuring long-term stability and esthetics.
