“…They are useful not only in prosthodontics but also in maxillofacial prosthetics. [1][2][3] Most commercially available magnetic attachments consist of two components: a keeper, which is generally made of stainless steel, and its corresponding magnetic assembly, which comprises a magnet and yoke made from ferromagnetic material. The magnetic assembly grips the keeper with a retentive force.…”

“…An overdenture with a magnetic attachment has many advantages, such as resistance of the denture to detachment, high esthetics, and a low burden on the teeth. Magnetic attachments are useful not only in prosthodontics but also for maxillofacial prosthetics (3,(13)(14)(15)(16)(17)(18)(19). Despite several case reports on the use of magnetic attachments, the influence of permanent magnets on living cells remains unclear.…”

Magnetic attachments are commonly used for overdentures. The deleterious effects of exposure to magnetic flux on human health have not been substantiated so far; nevertheless, there is a need to understand the extent of magnetic field exposure in the oral area resulting from the use of magnetic attachments. The purpose of this study was to investigate the influence of a magnetic field on oral squamous cell carcinoma. Tumor cells cultured on a magnetic plate were compared with those not cultured on a magnetic plate (controls). The cells were seeded at a density of 1 × 10 cells/well and cultured for 6 days. The influence of the magnetic field on cytokine production was examined by cytokine array analysis. Secretion of platelet-derived growth factor-AA (PDGF-AA) was measured by enzyme-linked immunosorbent assay and Western blotting. The expression of PDGF-AA messenger RNA was examined by real-time polymerase chain reaction, whereas nuclear factor-kappa B activity was measured by luciferase assay. The results indicated that the magnetic field inhibited the secretion of PDGF-AA, thereby inhibiting PDGF-AA-induced expression, thus reducing the risk of cancer recurrence.

“…Maeda et al [39] reported the method of replacing a missing abutment tooth of a removable partial denture with a magnetic attachment, a prefabricated keeper containing a post and a composite resin. They reported optimal support, bracing, retention and improved esthetics in short hours using this method.…”
