【Caution】

1. The dentist should consider known interactions and cross reactions of the product with other materials already in the patient's mouth before using the product.

2. Unpolymerized resin may lead to skin allergies.

3. Phenolic substances (e.g. eugenol) inhibit polymerization, therefore these materials (e.g. zinc oxide eugenol cements) must not be used as liners.

4. Discoloration may occur upon using of chlorhexidine or oral washing liquids.

【How to use】

1. Cavity preparation

Gently prepare the hard tissue according to the rules of the adhesive technique. When working on anterior teeth, bevel all enamel edges. Do not bevel the edges when working on posterior teeth. Avoid featheredged margins. Next, clean the cavity with water spray, remove all residues and dry. Complete drying is necessary. We recommend the use of a rubber dam.

2. Pulp protection /liner

When using an enamel-dentin adhesive, the liner can be foregone. In case of very deep cavities near the pulp, line with a calcium hydroxide compound accordingly.

3.   Design of approximal contacts

In cavities with approximal sections, set in a transparent matrix and fix.

4. Filling with Light-Cured Composite Resin

Apply the etching gel to the prepared surface, etch for 30 seconds on enamel or 15 seconds on dentin, then rinse off the etching gel thoroughly with water. Avoid drying the dentin. The dry, etched enamel surface will appear greyish white and must be kept free of contamination before the adhesive is applied. If the prepared area is contaminated with saliva, rinse and dry again. Etch again if necessary. Shake Bond LC well and apply the adhesive generously to the dentin and enamel surfaces with a brush, applying vigorously for approximately 30 seconds. Afterwards, blow dry carefully with oil-free compressed air for approximately 15 seconds. After curing the adhesive layer for 20 seconds using a polymerizing lamp (light-curing device), apply a second coat of adhesive in the same manner.

5. Application of the composite

Take the required amount of composite out of the application tip. Fill the cavity with the material and shape as needed by using conventional metal instruments. A layer thickness of 2 mm must not be exceeded. Due to the oxygen in the ambient air, a thin dispersion layer will remain on top of each layer. This dispersion layer forms the chemical bond between the layers and must not be touched or contaminated with moisture.

6. Polymerization

The polymerization time is 20 sec, per layer for colors with a commercial polymerization system, an LED polymerization lamp or 2 x 3 sec, with a plasma polymerization system. Hold the light-guide as close to the surface of the filing as possible. Fillings with several surfaces should be polymerized from the direction of each surface.

7. Finishing

Nano Composite can be finished and polished immediately after polymerization. Available grinding tools include finishing diamonds, flexible split disc silicone polishers and polishing brushes. Check the occlusion and functional movement, adjust if necessary, and finally polish with a suitable polishing paste.

Special instructions

The working range under a surgical light is 2 min. In case of extensive restorations, the surgical light should be moved away from the working area temporarily to avoid premature curing of the composite. Alternatively, the material can be covered with alight-tight foil.

Use a light polymerization system with an emission range of 450 nm and intensity of 500mW/cm2 to polymerize the material. The required physical properties are only reached if the polymerization light functions properly. Therefore, it is necessary to check the light intensity regularly.
