The field of science and technology has seen radical advancements and one such progression in the field of material science is nanotechnology. Nanotechnology deals with structure at the Nano scale and is one of the most crucial advancements of the 21st century, due to its economic and scientific potential. With the advent of nanotechnology, it has been applied in various fields in orthodontics from the coating of the surface to the innovation of new materials.
What Are Nano Particles?
Nano particles are particles produced in a calculated manner that has a typical dimension of 1 to 100 nm and has properties that are not shared by particles which do not belong to the nanoscale particles with the same chemical structure.
Application Of Nanotechnology In Orthodontics
Nanotechnology is used in the field of orthodontics to sustain good oral health. Silver nanoparticles are used as antimicrobial agents in the manufacturing of cement and resin bases of dentures, root canal columns and orthodontic sealants. The antimicrobial property in the particles decreases the build-up of plaque around the brackets. With the help of nanotechnology, we can reduce the friction and scuffing that happens to the mouth because of the braces. Nanotechnology is being used to make braces more friction resistance while also maintaining transparency. Researchers are still working on using NiTi nanotechnology that can give the dental wire shape-memory and super flexible properties.
- Nano Coatings in Arch Wires to Reduce Friction – Friction in the mouth is a major problem during orthodontic treatment. Nano coatings are used either on the bracket surface or NiTi wires to prevent abrasion.
- Orthodontic Brackets – The material with which the bracket is made contains polysulfone with hard aluminia nanoparticles for strength, decreased friction and biocompatibility while maintaining the transparency of the bracket.
- Nanoparticles Application as Antimicrobial Agent – Cavities and white spot lesions are common problems while undergoing orthodontic treatment due to the accumulation of plaque around the brackets. Silver, gold, silica, copper, nitrogen with titanium dioxide and zinc oxide nanoparticles have been coated on both brackets to prevent tooth decay during orthodontic treatment.
Uses Of Nanoparticles In Dentistry
Nanoparticles have been used for administering local anesthesia, diagnosis and cure of oral cancer and dressing wounds. Nanoparticles are used in dental materials which are used for restoration and dental procedures. They react effectively with microbial membrane and provide a larger surface area for anti-microbial activity.
There has been a lot of exploration on the application of nanotechnology in orthodontics and there’s a lot more work which needs to be done. Extensive research and improvisation in the field of nanotechnology is constantly being done so that the clinical application is available at a fair price to both the orthodontist and the patients.
