What is the biggest disadvantage of using resin cements?

The most significant disadvantage of using resin cements lies in the potential for debonding. Resin cements are designed to create a strong bond between restorative materials (such as crowns or bridges) and tooth structure. However, factors such as moisture contamination during the bonding process or incomplete curing can lead to a failure in the bond, resulting in restoration debonding over time. This can compromise the longevity and effectiveness of the restoration, necessitating additional treatments to re-establish the bond or replace the restoration entirely.

While difficulty in application, high cost, and limited shade options can be concerns with resin cements, they do not directly impact the functional durability of the restoration as much as the risk of debonding does. Ensuring a successful bond during the application process is crucial, and strategies to minimize potential debonding are key considerations for practitioners when utilizing resin cement in clinical practice.
