When studying various types of fixation of dentures, it was found that all the time, from the beginning of the use of permanent magnets in dentistry to the present day, only such properties of magnets as attraction and adhesion with the axial form of magnetization of these magnets were used. Modern materials for magnets must meet the requirements for each specific product. When choosing a material for a particular magnet, a specialist must have certain knowledge, but information on this topic is not enough in domestic sources, which mostly indicate only such parameters as coercive force (stability factor of permanent magnets) and the name of the magnetic material. Therefore, we consider the search and provision of information for a well-founded choice of magnetic fixation of dentures to be appropriate and relevant. The aom of the study is increasing the effectiveness of prosthetics for patients by deepening knowledge of the magnetic properties of materials and magnetic methods of fixation of dentures. Search and analysis of literary and scientific sources of information to expand knowledge on the use of magnetic devices. All magnetic retainers can be divided into three large groups: intermaxillary repulsive magnets of intraprosthetic location; single-jaw attractive magnetic implants; intra-root magnetic attractive retainers. In modern dentistry, the use of magnets in removable dentures is becoming increasingly popular. Today, various materials are used to manufacture magnets. These are alnico, ferrites, samarium-cobalt, neodymium-iron-boron, iron-chromium-cobalt alloys, as well as materials in the form of a mixture of magnetic powder and any binding component. Rubber, plastic and materials based on epoxy resin can act as a binding material. Each of the above materials has both advantages and disadvantages. The property of ferromagnetic materials is the basis for the manufacture of magnets. Neodymium and samarium-cobalt magnets are used to fix dentures. Neodymium magnets are a universal solution for fixing dentures. Thanks to the use of modern technologies, these magnets have impressive power in a small size. Reliable coating guarantees long-term service without loss of physical and magnetic properties.
