Background: Malocclusion is a disease with a high incidence rate that is harmful to humans’
health. Fixed orthodontics is an effective method for the treatment of malocclusion. However, the orthodontic
process takes a long time, requires frequent visits, causes pain, and increases the risk of complications.
Since orthodontic treatment is lengthy, painful and unbearable, and even leads patients to
abandon orthodontic treatment, therefore, how to shorten orthodontic treatment duration, and reduce
pain is a research hotspot in the orthodontic field.
Objective: The study aimed to provide an overview of the existing orthodontic accelerating device and
introduce their classification, characteristics and development.
Methods: This paper reviewed various productions and patents related to the orthodontic accelerating
device. The structural characteristics, differentiations, and applications of the existing orthodontic accelerating
device are also introduced.
Results: The existing orthodontic accelerating devices were analyzed and compared, and the typical
characteristics were concluded. The main problems in its development were analyzed, the development
trend was foreseen, and the current and future research on the productions and patents related to the
orthodontic accelerating device is discussed.
Conclusion: The orthodontic accelerating device is composed of a vibration device having electrical
stimulation, magnetic field, a low-level laser, and an ultrasonic device according to the application of
different physical loads. Orthodontic accelerating device can effectively reduce orthodontic treatment
time by 30%-50%, and can reduce the risk of complications and pain. The dose of the physical load
determines the effect of the device. So, an optimal loading dose should be selected . Compared with
vibrating devices, other types of devices are less used in clinical practice, therefore, such products and
patents should be invented in the future.
