• Low film thickness.
• High Compressive strength.
• Radiopaque.
• Neutralizes the hardness of phosphoric acid.
• Apply directly to prepared dentinal tissue

Zinc Phosphate Cement Zinc F+ is a zinc phosphate cement which has universal application for crowns and bridges and as a liner/core or base material. Zinc F+ offers an extremely accurate fit with very high mechanical strength. Neutralizes the harshness of phosphoric acid Cavity lining under all restorative materials. Apply directly to prepared dentinal tissue

ADVANTAGES

• Seals dentinal tubules and minimizes post-operative sensitivity
• Low film thickness
• High Compressive strength
• Radiopaque

INDICATION

• Cavity lining under all restorative materials.
• Cementation of crowns & bridges, inlays and orthodontics brackets.

DIRECTION TO USE

• Step 1: Shake Powder jar before use : Dispense 2 spoons full of powder and 56 drops of liquid on a cool glass slab.
• Step 2: While mixing heat is generated due to reaction, exothermic it is therefore advised to do mixing in fractions.
• Step 3: Add powder into liquid in small fractions to get the desired consistency.
• Step 4: Recommended fractions of powder into liquid is (1/8 or 1/4).
• Step 5: Continue mixing for 45-60 seconds to form a smooth paste.
• Step 6: Thoroughly rinse the tooth surface with water and gently air dry.
• Step 7: Thinly apply Zinc F+ over the tooth structure and the interfacing metal surfaces before they are joined.
• Step 8: For maximum bond strength Zinc F+ must be allowed to set 3:00-3:10 (min: sec) while metal and prepared tooth surfaces are compressed together.
• Step 9: For this it is advised that the patient bites hard onto a cotton ball without periodic relaxation.
• Step 10: Biting hard will remove excess cement and reduce its film thickness and improve the bond.
