Flowable light-curing nano-hybrid filling material.

Characteristics:-

• Ideal flowability
• Outstanding physical properties
• Excellent wetting properties
• Very high filler content (> 76 % w/w)
• Significantly less polymerisation shrinkage (3.2 %)
• Extremely high resistance to abrasion (ACTA < 35 μm)

Indications:-

• Filling minimally invasive cavities of all classes
• Filling small class I cavities and extended fissure sealing
• Filling class II - V cavities including V-shaped defects and cervical caries
• Blocking out undercuts
• Lining or coating cavities
• Repairing fillings and veneers
• Luting translucent prosthetic pieces (e.g. full ceramic crowns, etc).
• 
  
• Packaging:
• Refill syringe 1.8g
• 
  

• KEY SPECIFICATIONS :

  • Store at temperatures of 4 °C to 23 °C.
  • Polofil NHT Flow may be refrigerated, but must be allowed to reach room temperature before use.

DIRECTIONS TO USE :

Application:

Let the material reach room temperature before application. Place a matrix on cavities in the approximal area. Using transparent matrices is advantageous. Lock the application cannula (type 41) onto the syringe with a clockwise turn and apply Polofil NHT Flow directly. For fillings of more than 2 mm, apply and polymerise in layers.

Light-curing:

Conventional polymerisation devices are suitable for lightcuring this material. Halogen light devices should have a minimum light output of 500 mW/cm2 , LED lamps should have a minimum output of 300 mW/cm2 . The curing time is 20 s minimum per layer. Hold the tip of the curing light as close as possible to the surface of the filling. If the distance is more than 5 mm, the curing depth will be reduced. Insufficient curing can lead to discolouration and pulp irritation.

Finishing:

The filling can be finished and polished immediately after removing the shaping aids (e.g. fine and extra-fine grain diamonds, polishing discs). During finishing and polishing, the filling must be cooled. The margin of the filling, or even better, the entire tooth should be fluoridated as a final step.
