Which type of cement is recommended for cementing stainless steel crowns?

When selecting a cement for permanently cementing stainless steel crowns, the recommended choice is permanent polycarboxylate cement. This material provides an excellent balance of desirable properties for this specific application. Polycarboxylate cement has good adhesive qualities, which allow it to bond well to the stainless steel surface of the crown as well as to the tooth structure. This adhesion helps ensure the crown remains securely in place over time, promoting stability and longevity.

Furthermore, polycarboxylate cements are biocompatible and gentle on the tooth pulp, making them a safe choice for use in various dental procedures, including those involving stainless steel crowns. They also have sufficient strength to withstand the forces of chewing, which helps to maintain the integrity of both the crown and the underlying tooth.

In contrast, while other materials like glass ionomer and zinc phosphate cements have their advantages, they may not offer the same combination of adhesion and pulp protection that polycarboxylate does in this context. Therefore, the unique properties of permanent polycarboxylate cement make it the most suitable option for cementing stainless steel crowns.
