What is the purpose of Zinc phosphate Type 1 in dental applications?

Zinc phosphate Type 1 is primarily utilized in dental applications as a permanent cement for cementing crowns and bridges. Its formulation allows it to create a strong bond between the restoration and the tooth structure, providing durability and support under functional stresses. The properties of zinc phosphate, such as its compressive strength and resistance to solubility in the oral environment, make it an ideal choice for long-term retention of fixed restorations like crowns and bridges.

While other cements serve different purposes — such as temporary cement for provisional restorations or as bases for cavity preparations — zinc phosphate's role is specifically anchored in its ability to firmly and reliably secure permanent restorations within the dental arch, ensuring their stability and longevity.
