Microbiome modulation of implant-related infection by a novel miniaturized pulsed electromagnetic field device
Investigated the role of PEMF to control biofilm accumulation and modulate its microbial composition using polymicrobial models that considered a human microbiome.
This represents a breakthrough in prevention effect of peri implant diseases and effect on implant longevity.
Lower levels of P. Gingivalis and pathogen T. Forsythia, – both have been linked to peri-implant tissue destruction were reduced by PEMF.
25 or more bacterial species were reduced by PEMF – shows a potent modulatory effect driven towards a health associated microbial profile.
Electrostatic forces are responsible for mediating bacterial-bacterial interactions and surface attachment, hence responsible for the results seen in this study.
Long term peri implantitis non-surgical treatment
Our study provides compelling evidence that Magdent’s PEMF healing abutment significantly
enhances clinical outcomes in peri-implantitis treatment compared to standard care.
Key benefits include:
• Complete plaque elimination
• Substantial reduction in probing depth and bleeding
• Elimination of infection
• Stabilization or regeneration of bone
• Higher overall success rate
The results support the integration of PEMF technology as a therapeutic adjunct in the
management of peri-implant diseases, particularly in difficult or refractory cases.
The PEMF group achieved complete plaque elimination, a 75% reduction in bleeding on probing, and a 2.7 mm reduction in pocket depth. Unlike the control group, which showed bone loss, the PEMF group maintained or gained bone. Overall treatment success was 71.4%, compared to 50% in the control group – a ~40% improvement.

Bone Regeneration Revolution: Pulsed Electromagnetic Field Modulates Macrophage-Derived Exosomes to Attenuate Osteoclastogenesis
PEMF not only reduces the inflammatory activity of macrophages and the degradative activity of osteoclasts but that the EVS produced by macrophages, obtained from PEMF treatment, positively affect osteoclasts by reducing their activity.
This finding underscores the crucial role of EVs-mediated signaling in modulating osteoclastogenesis and highlights the potential for EVs to influence bone remodeling by maintaining a delicate balance between bone formation and resorption.

Pulsed Electromagnetic Fields in Bone Healing: Molecular Pathways and Clinical Applications
PEMFs have been widely used to enhance bone repair, accelerating healing process of recent fracture by promoting the callus formation, which can be achieved through four distinct phases: inflammatory, angio-mesenchymal, bone formation, and remodeling phases.
PEMF is a noninvasive, therapeutic form of low field magnetic stimulation that has been used for healing bone non unions and various fractures.
