Abstract: BACKGROUND: The regeneration of bone tissue not only needs biomaterials, but also depends on the self-healing ability of the body. However, due to age-related physiological and pathological changes, the regeneration ability of bone tissue will be weakened. Therefore, magnetic field as an auxiliary treatment has been concerned.

OBJECTIVE: To introduce the biological effect of magnetic field and the progress of magnetic field used to promote the bone responses to metal implants, bioceramic scaffolds and polymer composites.
METHODS: The English literature search was performed in PubMed, EMBASE and EI databases from 2014 to 2020. The keywords were “magnetic fields, magnetic nanoparticles, implant, bioceramic scaffold, calcium phosphate scaffolds, hydroxyapatite, polymer materials, bone growth, bone regeneration, osseointegration, bone remodeling, osteoblasts, osteoclasts, mesenchymal stem cells, signaling pathways”. Totally 52 articles were finally selected for analysis. 
RESULTS AND CONCLUSION:  (1) Magnetic field can regulate the proliferation and differentiation of osteoblasts, osteoclasts and mesenchymal stem cells, playing the role of osteogenic induction. (2) Wnt, RANK, MAPK and other signaling pathways play critical roles in magnetic field-mediated osteogenesis. Magnetic field affects bone metabolism by regulating the expression of osteogenic markers on these pathways. (3) Magnetic field can promote bone responses to implants, bioceramic scaffolds, and polymer materials. Thus, the combination of magnetic field and these biomaterials can improve bone regeneration and repair. (4) The best conditions for magnetic field to promote osteogenesis is not confirmed, and the magnetic field parameters should be carefully chosen in clinical practice. In addition, there are many theories about the mechanism of magnetic field-induced bone formation, and the detailed mechanism requires to be further studied.
