In the pursuit of increasing treatment efficiency and decreasing treatment duration, vibratory stimulation has been advocated as a possible adjunct to orthodontic appliances to increase the rate of tooth movement. Following this, a new device called the Acceledent has become commercially available, and is aimed at decreasing treatment duration by accelerating periodontal and bony tissue remodeling with low magnitude high frequency vibration. Surgical methods, regardless of technique, are still invasive to some degree, and hence have their associated complications. Hence, non-invasive methods have come to the force. Vibration was mostly investigated and gave the most promising results. The concept of using physical approaches came from the idea that applying orthodontic forces causes bone bending (bone bending theory) and bioelectrical potential develops. The concave site will be negatively charged attracting osteoblasts and the convex site will be positively charged attracting osteoclasts.
