Aesthetic and adhesive cementation for contemporary porcelain crowns.

The evolution of aesthetic restorative materials has led to the development of new preparation designs and cementation protocols. While conventional cements were able to provide mechanical and macromechanical retention for restorations with limited aesthetic expectations, resin cements with micromechanical retention have been formulated as aesthetic alternatives. The objective of the present article is to establish the differences between conventional and adhesive crown cementation techniques, as well as to provide guidelines for reducing postoperative sensitivity and improving aesthetic and functional results.
