Numerous benefits of magnets for leaving tissues are well known in medicine. The most popular are: inhibition of bacterial and fungal growth, anti-inflammatory effect, increase of metabolic process in the inflamed tissue, increase of elimination of inflammatory mediators, analgetic effect, osteogenetic and healing effect. The benefit of magnetic stimulation are also numerous. However, the most important thing is that magnetic stimulation is very simple and non-invasive method. There is a great interests in stomatology for this kind of therapy. The magnets have been applied in prosthetic dentistry, orthodontics and parodontology. The magnets have a very long tradition in removable prosthetic dentistry. They have been mostly used in retention of removable dentures. However, their osteogenetic effect are also interesting in prosthetic dentistry. The regenerative processes stimulated by static magnetic field are very similar in the human long bones and jaw ones. Therefore, the positive effects of magnetic field in healing of the long bone fractures can be applied in the prosthetic therapy of patients with the last remaining teeth. Magnets which are used for these purposes should be compatible with the oral tissues and resistant to the corrosive processes in the oral environment.
