“…46 Studies on a rat model have shown that the support of active orthodontic elements operating with a force of about 20 g, both using a PEMF of 1.8 mT (or 1.5 mT) and a Nd-Fe-B magnet (neodymium), increases the distance a tooth can be moved. 47,48 Stark and Sinclair and Showkatbakhsh et al also confirmed the accelerating action of PEMF. 32,49 The clinical trial by Showkatbakhsh et al, assessed the distalization of the canine after 1 st premolar extraction, using a removable PEMF-generating device with an intensity of 0.5 mT and a frequency of 1 Hz.…”

Technological progress and the introduction of modern therapeutic methods are constantly changing contemporary orthodontics. More and more orthodontic patients are working adults, who expect satisfactory therapeutic effects as soon as possible, increasing the importance of methods accelerating tooth movement. The aim of this study was to review the current literature regarding methods of accelerating tooth movement and reducing the duration of the active phase of therapy. The literature was collected from the PubMed and EBSCO databases using "accelerated orthodontic tooth movement" as the search key words. The methods described were categorized as conservative and surgical. The pharmacological agents used in conservative treatment, such as growth hormone, parathyroid hormone, thyroxine, and vitamin D, are especially worth mentioning. They stimulate osteoclasts to increase resorption through a variety of mechanisms. Effective methods also include physical stimuli, e.g., vibrations or photobiomodulation. Most studies describing the effects of pharmacological agents were based on animal subjects and they may therefore lack clinical relevancy. Corticotomy and its modifications based on the regional acceleratory phenomenon (RAP) might prove to be a useful augmentation of orthodontic treatment, especially in adults, including patients with periodontal disease.

To evaluate the effect of diode laser use on experimental orthodontic tooth movements. Methods: Thirty Rattus norvegicus albinus Wistar were divided into three equal groups (n = 10), two experimentals and one control. Applying 20 g orthodontic force were attached to the maxillary incisors of the rats in all groups. Low dose laser was applied to the surrounding tissues of the maxillary incisors of the rats in the experimental groups. Two exposure times for laser irradiation were used for seven days: t = 12 min (energy dose = 72 J) and t = 9 min (energy dose = 54 J) by a 0.1 W DEKA brand diode laser with wavelength of 980 nm. Results: Osteoclastic activation increased in the 72 J group when compared to control group and decreased in comparison to the 54 J group. Osteoblastic activation was decreased in the 72 J group when compared to the control group and increased in comparison to the 54 J group. Conclusions: Applying 54 J laser energy has been found effective to accelerate the orthodontic tooth movement.

“…Moreover, the studies that were done on animals, shown that the application of low-intensity pulsed ultrasound caused an acceleration of the process that lead to new bone formation. The pulsed electromagnetic fields (PEMFs) application influence bone metabolism [3]. Several studies demonstrated that electromagnetic fields accelerate the bone formation.…”

Background: The rate of orthodontic tooth movement depends on two general factors: the forces used in order to cause orthodontic tooth movement and respectively the individual (biological) response of the body to these forces. Objective: The aim of this review is to offer an overview of the factors that has been mentioned in literature to accelerate the biologic response to orthodontic forces. Data Sources: PubMed, Google Scholar and Scopus databases were used. Study selection: We included in our study controlled clinical trials, but also randomized controlled trials and even cases series with more than 5 subjects that aimed to evaluate alternatives methods in accelerating the rate of orthodontic tooth movement. Publications published until April 2018 were included. Data Extraction: All the factors that had been mentioned in literature to have a positive influence on the rate of orthodontic tooth movement were synthesized and described as a review. These methods are the followings: physical, surgical and chemical agents. Physical factors are easy to apply, surgical factors are invasive and the pharmacological agents we described in this article are: prostaglandin E2 (PGE2) and vitamin D3. Data Synthesis: The alternatives methods that accelerate the rate of orthodontic tooth movement modulate the biologic response of the periodontal ligament to the mechanical forces. Vitamin D3 was mentioned as the most biopotent agent in accelerating the rate of orthodontic treatment. Although it has biomodulator effect on bone tissue, supplementary studies are needed in order to clarify what is the exact reduction of orthodontic treatment period.
