Vibrations in orthodontics: Is it the future?

Ever since the advent of orthodontic therapy, time required for orthodontic treatment has always been under the scanner. Various studies have been done solely for the purpose of decreasing the treatment time. Few methods were invasive while others are not successful enough in accelerating the treatment time. One of the latest methods to accelerate orthodontic treatment is the use of high-frequency small-magnitude vibrations at specific locations. Various animal studies have already been carried out to enhance the methods used to increase orthodontic tooth movement (OTM) and in turn decrease the treatment time. Electronic databases of PubMed library were searched from 1998 to 2018. Ten clinical studies were evaluated after considering the inclusion and exclusion criteria. It was concluded that high-frequency low-magnitude vibrations can increase OTM by activation of receptor activator of nuclear factor-kappa B/receptor activator of nuclear factor-kappa B ligand pathway and stimulating the periodontal tissues.
