Ammdent Zinc Phosphate Cement

Ammdent Zinc Phosphate Cement is a versatile dental product used for luting permanent metal restorations and as a base in dental procedures. With its low initial pH, it provides strong adhesive properties but requires careful application to prevent pulpal irritation, especially in cases where thin layers of dentine separate the cement from the pulp.

To ensure optimal results, it is essential to follow proper procedures and precautions. The powder-to-liquid ratio varies depending on its intended use: 1.0-1.3g of powder to 0.5ml of liquid for cement, and 1.2-1.5g of powder to 0.5ml of liquid for base applications. The mixing technique involves gradually incorporating the powder into the liquid until a plastic consistency is achieved, with a mixing time of approximately 90 seconds. Setting times range from 2.5 to 8 minutes for cement and 2 to 6 minutes for the base.

Indications

• Luting permanent metal restorations.
• Serving as a base in dental procedures.

• Adhesive Properties: Strong with low initial pH
• Environmental Conditions: 22-24°C temperature, 50±10% humidity
• Mixing Surface: Clean, dry glass mixing slab or paper
• Mixing Tool: Non-corrosive spatula, free from dust
• Powder-to-Liquid Ratio: Cement: 1.0-1.3g powder to 0.5ml
• liquid, Base: 1.2-1.5g powder to 0.5ml liquid
• Mixing Technique: Gradual addition of powder to liquid until plastic consistency is achieved
• Mixing Time: Approximately 90 seconds
  Setting Time: Cement: 2.5 to 8 minutes, Base: 2 to 6 minutes
• Compressive Strength (after 24 hours): 70 MPa

• 1 x 30gm powder
• 1 x 15ml liquid

Preparation:

• Ensure the working environment is at a temperature of 22-24°C with a humidity level of 50±10%.
• Use a clean, dry glass mixing slab or paper as the mixing surface.
• Ensure the mixing tools, particularly the spatula, are non-corrosive and free from dust or contaminants.

Powder-to-Liquid Ratio:

• For cement applications, measure 1.0-1.3 grams of powder for every 0.5 milliliters of liquid.
• For base applications, measure 1.2-1.5 grams of powder for every 0.5 milliliters of liquid.

Mixing Technique:

• Divide the powder into portions: one portion comprising 1/6th and the other two portions each comprising 2/6th.
• Gradually add the 1/6th portion of powder into the placed liquid and mix thoroughly.
• Continue adding the remaining powder portions one by one, ensuring thorough mixing until a plastic consistency is achieved.
• The entire mixing process typically takes around 90 seconds.

Timings:

• Aim for a mixing duration of 1.5 minutes.
• The setting time ranges from 2.5 to 8 minutes for cement applications and 2 to 6 minutes for base applications.

Application:

• Apply the mixed cement or base as per the intended dental procedure, ensuring proper placement and coverage of the restoration or cavity.
• Follow standard dental practices and protocols for cementation or base placement.

Curing:

• Allow the cement or base to set according to the specified setting time.
• Monitor the restoration or treated area during the setting process to ensure proper adaptation and curing.

Post-Application Care:

• Follow up with standard post-operative care procedures as per dental practice guidelines.
• Monitor patient comfort and restoration integrity during subsequent appointments.
