An overview of nanotechnological advances in orthodontics

Nanotechnology is the field of science dealing with the manipulation of the matter at the nanoscale level. The science of nanotechnology has emerged as a promising concept in all fields of medicine including dentistry and its scope is increasing everyday. It has also gained relevance in the field of orthodontics owing to its wide range of applications ranging from nanocoatings in archwires and brackets, orthodontic bonding, antimicrobial properties, atomic force microscopy to some future applications such as shape memory polymers, mandibular growth stimulation with gene therapy, acceleration of orthodontic movement, and use as biomechanical sensors. The enormous range of application of nanotechnology in orthodontics demands an intensive research into its current and future usages. This article aims to review and discuss the various applications and its potential usage in orthodontics.
