“…Because bone tissue has piezoelectric properties, i.e., it produces electrical polarization when subjected to mechanical deformation, human clinical trials and animal experiments have emerged associating bone repair through the therapeutic use of electricity [7,10]. Due to its action on various cell types and tissues [9,[11][12][13][14][15], it becomes a safe and non-invasive treatment for various conditions such as ulcers and chronic inflammatory diseases, especially those affecting the bone tissue [7,9,11,[16][17][18].…”

Objectives The present study aims to evaluate two protocols of pulsed electromagnetic field (PEMF) on osseointegration and establish one that addresses ideal parameters for its use in dentistry, especially in the optimization of the implants osseointegration process. Materials and methods Sixty male rats (Wistar) were allocated into three experimental groups: control (GC), test A (GTA, 3 h exposed), and test B (GTB, 1 h exposed). All animals received titanium implants in both tibias, and PEMF application (15 Hz, ± 1 mT, 5 days/week) occurred only in the test groups. They were euthanized at 03, 07, 21, and 45 days after PEMF therapy. Removal torque, histomorphometric measurements, three-dimensional radiographic evaluation, and in vitro biological assay analyses were performed. Results GTB showed better results compared with GTA in removal torque tests, in bone volume and bone mineral density, cell viability, total protein content, and mineralization nodules (p < 0.05). GTA showed better performance in trabecular bone thickness and cell proliferation compared with GTB (p < 0.05), especially at osseointegration early periods. In the histomorphometric analysis and number of trabeculae, there were no differences in the test groups. Conclusion PEMF as a biostimulator was effective in optimizing the events in bone tissue that lead to osseointegration, especially when applied for a shorter time and in the initial periods of bone healing. Clinical relevance The PEMF therapy is an effective alternative method for optimizing bone healing.

“…The majority of clinical investigations regarding PEMF application showed positive effects on implant osseointegration, with an increased implant stability, a higher perimplant radiodensity and a significantly lower bone loss compared to controls [60][61][62]. Bud et al [59] did not report statistically significant differences in radiodensity around implants (considered as an approximation of actual bone contact with implants) receiving PEMF stimulation or not.…”

“…Two studies are RCTs, one is a CCT and one is a retrospective study. The first RTC study [62], pioneered the evaluation of PEMF advantages in clinical settings, showing that implants exposed to PEMF (2 h/day for 12 days with a frequency of 2 Hz applied in the first hour, 4 Hz in the second hour) had a higher radiodensity immediately postoperatively and until 1, 3, 6, and 12 months compared to unexposed ones. Also, a significantly lower bone loss was measured up to 1 year follow-up, but no statistical differences were observed regarding the stability of the implants, measured by RFA, probably due to the small size of the analyzed groups.…”

Effects of Magnetic Stimulation on Dental Implant Osseointegration: A Scoping Review

et al. 2022

View full text Add to dashboard Cite

This PRISMA-ScR driven scoping review aims to evaluate the influence of magnetic field stimulation on dental implant osseointegration. Seven databases were screened adopting ad-hoc strings. All clinical and preclinical studies analyzing the effects of magnetic fields on dental implant osseointegration were included. From 3124 initial items, on the basis of the eligibility criteria, 33 articles, regarding both Pulsed ElectroMagnetic Fields (PEMF) and Static magnetic Fields from permanent Magnets (SFM) were finally included and critically analyzed. In vitro studies showed a positive effect of PEMF, but contrasting effects of SFM on bone cell proliferation, whereas cell adhesion and osteogenic differentiation were induced by both types of stimulation. In vivo studies showed an increased bone-to-implant contact rate in different animal models and clinical studies revealed positive effects on implant stability, under magnetic stimulation. In conclusion, although positive effects of magnetic exposure on osteogenesis activity and osseointegration emerged, this scoping review highlighted the need for further preclinical and clinical studies. More standardized designs, accurate choice of stimulation parameters, adequate methods of evaluation of the outcomes, greater sample size and longer follow-ups are needed to clearly assess the effect of magnetic fields on dental implant osseointegration.
