The awareness of the society and, accordingly, the number of patients who need orthodontic treatment has increased gradually. Nowadays, the importance of the concept of time has focused the attention of researchers on the completion of orthodontic treatments in a shorter time. Heavy forces applied to shorten the treatment period in orthodontic treatments cause many undesirable conditions, such as root resorption, crushing of periodontal fibers, and formation of hyalinization tissue. Therefore, researchers are working on methods that will accelerate orthodontic tooth movement and shorten the treatment time. In this section, applications that accelerate orthodontic tooth movement will be discussed.
