Which type of cement is designed for long-term cementation?

Permanent cement is specifically formulated for long-term cementation of dental restorations or appliances. It is characterized by its superior durability and strength, which allows it to securely bond restorative materials to dental structures over extended periods. This type of cement is often used in procedures such as the placement of crowns, bridges, and inlays, where a stable and lasting bond is critical for the longevity of the restoration and the overall oral health of the patient.

In contrast to permanent cement, temporary cement is designed for short-term use and allows for easy removal of the restoration when necessary. Glass ionomer cement can be used for both temporary and permanent applications; however, its primary strengths are not as high as some permanent cements. Zinc oxide eugenol is often utilized for its sedative effects on the pulp and can be used in temporary situations, but it does not provide the long-term adhesion required for a permanent solution. Hence, the focus on strength and longevity in the composition of permanent cement makes it the ideal choice for lasting dental applications.
