Zinc Phosphate Cement – Durable Dental Luting Agent

Zinc Phosphate Cement – Durable Dental Luting Agent is a time-tested luting material that delivers a chemically bonded, high‑strength interface between permanent restorations and tooth structure. Its formulation of zinc oxide powder mixed with phosphoric acid liquid ensures reliable adhesion for crowns, bridges, onlays, inlays, and orthodontic bands.

When applied, this cement provides excellent retention, maintains biocompatibility, and has a proven record of long‑term clinical success in permanent restorative procedures. That makes it a staple choice for practitioners seeking dependable long‑term outcomes.

Key Features

• Dual–component system: 75% zinc oxide powder and 25% phosphoric acid liquid for optimal reactivity.
• Immediate wetting in situ: powder/ liquid ratio of 0.53–0.58 g/ml for a smooth, paste‑like consistency.
• Rapid setting time of 5–7 minutes, allowing efficient chairside workflow.
• High compressive strength exceeding 20 MPa, resisting occlusal forces in permanent restorations.
• Excellent adhesive bond strength to enamel and dentin, reducing micro‑leakage.
• Biocompatible formulation with minimal cytotoxicity, suitable for lifelong use.
• Stable pH range of 2.5–3.0 during setting, preventing pulp irritation.
• Versatile packaging in 25‑gram tubes, ideal for clinic or laboratory use.
• Consistent performance across temperature variations typical of oral environment.

Clinical Uses

• Cementation of ceramic, metal–ceramic, and zirconia crowns for permanent restoration.
• Attachment of fixed partial dentures (bridges) to abutment teeth.
• Luting of onlays and inlays with high bonding reliability to tooth structure.
• Secure placement of orthodontic bands on mandibular or maxillary arches.
• Adjunct to composite resin buildups where a durable bonding matrix is required.
• Multilayered restoration of deep carious lesions after cavity preparation.
• Temporary anchorage device bonding for orthodontic space management.
