Which material is primarily used for the final cementation of crowns?

The primary material used for the final cementation of crowns is luting cement, such as resin or glass ionomer cement. These types of cement are specifically formulated to provide strong, durable bonding between the crown and the tooth structure. Resin cements offer excellent adhesive properties and are suitable for various crown materials, allowing for an aesthetic finish with minimal impact on the underlying tooth structure. Glass ionomer cements, on the other hand, not only bond well to both tooth and crown materials but also release fluoride, which can help in protecting against recurrent caries.

In contrast, dental filling material is not designed for the specific purpose of cementing crowns; it is intended for repairing cavities. Temporary cement is used for provisional crowns, serving only short-term functions until a permanent cement can be applied. Composite resin, while it has adhesive qualities, is generally used for direct restorations and may not provide the same durability and bonding characteristics required for crown cementation. This distinguishes luting cement as the preferred choice for achieving a long-lasting and effective bond in crown restorations.
