Since their invention, rare earth magnets, which are small but provide strong attractive force, have often been used to retain dentures and maxillofacial prostheses. However, magnetic attachments are not without their problems.One problem involves the corrosion of rare earth magnets in oral fluid and the associated risk of a significant loss of magnetic attraction.Another problem involves the magnitude of the attractive force provided by the magnet.Although rare earth magnets are much stronger than conventional magnets, they do not provide adequate attractive force for denture-retaining devices.To increase the attractive force, small encapsulated magnetic attachments with stainless steel yokes were developed.Along with these issues, this article reviews the structure materials, characteristics, and biological properties of magnetic attachments.Structure and characteristics of magnetic attachmentsrare-earth magnetmagnetdentureretainer
