title: Evaluation of leakage flux out of a dental magnetic attachment.
abstract: A dental magnetic attachment is a device to retain dental prostheses such as overdentures by magnetic attraction. As compared with mechanical attachments, the magnetic attachment has a superior retention properties due to less lateral pressure to its abutment tooth, and hence it has come to be widely used, particularly for retaining overdentures. Because the dental magnetic attachments are a device used in the mouth, the tissues in the mouth are exposed to the magnetic fields leaking out of the magnetic attachments for a long time. It may therefore be important to discuss biological effects of the leakage magnetic fields. It is required at first to evaluate the strength of the leakage magnetic fields.
