Nanofyllning

Nanofyllning refers to the use of extremely small particles, measured in nanometers, as a component in various materials and products. This technology leverages the unique properties that arise when materials are reduced to the nanoscale, such as increased surface area to volume ratio, enhanced reactivity, and altered mechanical or optical characteristics. Nanofyllning can be applied to a wide range of substances, including polymers, ceramics, and composites, to improve their performance.

In the field of dentistry, nanofyllning describes a type of dental composite material that incorporates nanoparticles. These nanoparticles, often made of silica or zirconia, are significantly smaller than traditional filler particles. The smaller size allows for better packing within the resin matrix, resulting in a more homogenous and less porous restoration. This can lead to improved aesthetics, higher strength, better wear resistance, and reduced shrinkage during polymerization. Nanofilled composites are widely used for both anterior and posterior restorations due to their ability to mimic the natural appearance of teeth and their durability. The precise size and distribution of these nanoparticles are critical to achieving the desired properties of the nanofyllning material.
