Preparation and Pre-Treatment
Ensure surfaces are clean and dry. Sandblast with aluminum oxide‚ etch with HF gel‚ and apply silane as per instructions. Avoid moisture contamination for optimal bonding.
Cleaning and Sandblasting Surfaces
Clean and dry the surfaces thoroughly. Sandblast with 30-50 µm aluminum oxide at a 2-10 mm distance for 15 seconds. Use water-free‚ oil-free air to remove residues. Avoid using H2O2 or desensitizers. For zirconia or ceramic restorations‚ etch with HF gel and rinse. Ensure surfaces are free of contaminants for optimal bonding. Follow all safety precautions during sandblasting and cleaning to achieve proper surface preparation.
Etching and Silane Application
Etch the restoration surface with HF acid for 15 seconds‚ then rinse thoroughly. Apply silane according to manufacturer’s instructions‚ ensuring complete coverage. Allow silane to react for 5 seconds before air-drying. This step enhances bonding between the restoration and cement. Proper silane application is crucial for optimal adhesion and long-term durability of the restoration. Always follow specific product guidelines for best results.
Drying and Surface Readiness
After sandblasting and etching‚ thoroughly clean the surface with water-free‚ oil-free air to remove residues. Ensure the surface is completely dry before applying silane or cement. Any moisture can compromise bonding. Use compressed air to eliminate dust and debris. Proper drying ensures optimal surface readiness for cementation‚ promoting a strong and durable bond between the restoration and tooth structure.
Cementation Procedure
Activate the capsule‚ apply cement evenly‚ and seat the restoration. Hold in place‚ then light cure as instructed for optimal bonding and setting of the cement.
Step-by-Step Application Process
Insert the capsule into the activator‚ press the handle fully‚ and hold for 2-4 seconds. Apply the cement evenly to the restoration and tooth surfaces. Gently seat the restoration‚ ensuring proper alignment. Light cure as per instructions‚ typically 15-20 seconds. Allow the cement to set before final adjustments. Excess material can be removed with a scaler or floss. Ensure all steps are followed precisely for optimal bonding and durability.
Activation and Mixing Instructions
Insert the capsule into the activator and press the handle fully‚ holding for 2-4 seconds. This activates the mixing mechanism‚ ensuring even distribution of the cement.
