“…Piezoelectricity is generated by orthodontic forces bending alveolar bone to produce an electrical charge which, in turn, induces an osteogenic response . It has been suggested that orthodontic forces should not be continuous as the piezoelectric charges are only created when stress is applied and released . A vibrational appliance may therefore be suitable for initiating these stress‐induced charges as forces could be applied and released at a rapid rate.…”

Accelerated orthodontic treatment ‐ what's the evidence?

The demand and accessibility of orthodontic care has increased but has also been accompanied by patient requests for shorter treatment times. Longer orthodontic treatment increases the risk of decalcification, gingival recession, and root resorption and so shorter treatment times have multiple advantages as well as appealing to patient's desires. Numerous techniques and materials have been suggested to reduce treatment times but, in most cases, are based upon selected case reports with no prospective clinical trials to validate claims. The present review examines many of the current options purported to accelerate orthodontic tooth movement and the level of evidence presently available. There is some evidence to suggest that low-level laser therapy and a corticotomy involving the raising of a muco-periosteal flap are associated with accelerated orthodontic tooth movement; however, the current level of evidence is low to moderate in quality. For this reason, further research is required before routine application could be recommended.

“…15 Application of vibrational force initiates stress-induced charges by rapidly applying an intermittent force. Shapiro et al 16 have suggested that an increase in the rate of tooth movement occurs when the orthodontic forces are cyclic in nature, which is essential for generation of piezoelectric charges. These charges induce microcurrents to flow through bone and soft tissue and may enhance tooth movement by stimulating osteoblastic and osteoclastic activity.…”

Introduction: The objective of this systematic review is to assess the effect of vibrational force on biomarkers for orthodontic tooth movement. Methods: An electronic search was conducted for relevant studies (up to December 31, 2020) on the following databases: Pubmed, Google scholar, Web of Science, Cochrane Library, Wiley Library, and ProQuest Dissertation Abstracts and Thesis database. Hand searching of selected orthodontic journals was also undertaken. The selected studies were assessed for the risk of bias in Cochrane collaboration risk of bias tool. The “traffic plot” and “weighted plot” risk of bias distribution are designed in the RoB 2 tool. The 2 authors extracted the data and analyzed it. Results: Six studies fulfilled the inclusion criteria. The risks of biases were high for 4, low and some concern for other 2 studies. The biomarkers, medium, device, frequency and duration of device, as well as other data were extracted. The outcomes of the studies were found to be heterogenous. Conclusion: One study showed highly statistically significant levels of IL-1 beta with <.001. Rate of tooth movement was correlated with levels of released biomarkers under the influence of vibrational force in 3 studies, but it was found to be significant only in 1 study. It was further observed that vibration does not have any significant reduction in pain and discomfort.

“…Both in vitro and in vivo studies have shown that fully controlled pulsating orthodontic force can shorten the treatment period by potentially preventing the damage to capillary vessels within the PDL [ 1 – 4 ]. The effect of intermittent force versus continuous force on the amount of molar movement was examined in rats [ 3 ].…”

“…It is also indicated that there is a diurnal variation regarding the tooth’s response to orthodontic force, and that the force applied during the animal’s rest period may be more effective than that applied during its active period. Notably, when pulsating force was applied to human maxillary molars, it is found that both the rate of movement and the total movement of the treated tooth was greater than that of the controlled tooth [ 1 ].…”

A randomized trial on the effects of root resorption after orthodontic treatment using pulsating force

et al. 2020

Background An orthodontic device that moves teeth with pulsating force was invented and underwent a single center, controlled, clinical trial to test its safety and efficacy for treatment. The device has a custom-made thermo-plastic mouthpiece which fits over the teeth with an inflatable silicone element. A console that measures and controls the pulsating force level in real-time controls the air pressure that delivers a pulsating force. In this study, the effect of the device on root resorption during orthodontic treatment was evaluated using 3D cone beam computed tomography and compared with a control group of patients who received Invisalign treatment. Methods Twenty-eight subjects were enrolled in the investigational arm and 15 in the control group. Subjects were followed until the average score of the mandibular and maxillary teeth achieved a Little’s Irregularity Index of 1.5 mm or less. Results There were no adverse events reported throughout the study for either treatment arm. No clinically significant root resorption was observed for either group. The investigational device did not cause root resorption greater than the control group. Both devices produced a safety profile compared to current orthodontic techniques. Conclusion The investigational device did not produce more root resorption than similar conventional orthodontic appliances. Trial registration ClinicalTrials.gov, NCT03421886 . Registered 12 January 2018 - Retrospectively registered.
