Which type of dental cement is primarily used for long-term restorations?

Final cement is the type of dental cement primarily used for long-term restorations due to its properties that provide strong adhesion and durability, essential for maintaining the integrity of restorations over time. This type of cement is designed to withstand the forces of mastication and to bond effectively to both tooth structure and restorative materials, ensuring that crowns, bridges, inlays, and onlays remain securely in place for extended periods.

In contrast, temporary cement is formulated for short-term use, allowing for easy removal of restorations when necessary. Base cement serves a different purpose as it typically serves to protect the pulp or as a thermal insulator beneath restorative materials. Impression cement is used in the process of taking dental impressions and does not provide the adhesive properties required for long-term maintenance of dental restorations.
