What is zinc phosphate used for in dentistry?

Zinc phosphate is primarily used in dentistry as a cement for dental restorations. Its composition allows it to provide strong adhesive properties and durability, making it suitable for cementing crowns, bridges, and inlays. The material also acts effectively under various conditions in the oral environment, contributing to reliable binding of the restoration to the tooth structure.

While zinc phosphate can have some applications in providing thermal insulation, its primary role is rooted in cementation, particularly due to its strength and longevity which are crucial for maintaining the integrity of dental restorations over time. This characteristic is what differentiates it from other materials that may serve other purposes in dentistry, such as bonding agents or liners.
