In the field of dentistry, the pursuit of biocompatible and effective materials has led to the development of numerous innovative solutions. Yet, certain classic compounds continue to hold their ground, proving their enduring value through decades of clinical success. Zinc Phosphate (CAS 7779-90-0) is one such material, a staple in restorative dentistry renowned for its utility as a dental cement. As a trusted supplier of fine chemicals, we recognize the critical role this compound plays in dental health and procedures.

Zinc Phosphate cement, derived from Zinc Oxide and Phosphoric Acid, has been a workhorse in dentistry for over a century. Its long history is a testament to its predictable performance and favorable properties. It is primarily used for luting permanent restorations, such as crowns, bridges, and inlays, providing a stable and reliable bond to tooth structure and restorative materials like metal and zirconium dioxide. Its simple mixing process, typically a powder-liquid system, contributes to its widespread adoption and ease of use by dental professionals.

The zinc phosphate dental cement offers a unique combination of benefits. It exhibits high compressive strength, which is crucial for supporting occlusal forces, and a low film thickness, allowing for precise seating of restorations. While it possesses a relatively low flexural strength compared to newer materials, its overall performance profile, coupled with its good price-performance ratio, ensures its continued relevance. Furthermore, its low sensitivity to moisture during placement makes it a forgiving material in the often-challenging oral environment.

Beyond its luting capabilities, Zinc Phosphate cement also serves as a base or liner under dental restorations. Its biocompatibility means it can be placed in close proximity to the dental pulp without causing significant irritation, acting as a protective barrier. This makes it an excellent choice for protecting the pulp from thermal changes or the acidity of other restorative materials, such as composite fillings. The ability to easily remove excess cement after setting further adds to its practical advantages.

While modern dental materials continue to evolve, the fundamental strengths of Zinc Phosphate cement persist. Its proven track record, combined with its reliable performance and cost-effectiveness, makes it an indispensable material in many dental practices. For dental professionals seeking a time-tested and dependable cementation solution, understanding the properties and applications of Zinc Phosphate is essential. We are proud to supply high-quality Zinc Phosphate that contributes to successful and lasting dental restorations, upholding the legacy of this important material.
