Many different theories are dissensed for the use of electromagnetic fields for the cure of a many diseases in the science field. Scientists are trying to find out the exact mechanism of the magnetic fields. Especially the ones that are natural and can be seen in our daily lifes plays an important role. The aim of using electomagnetic fields is to mimic the natural healing thus the nature. It is a well known hypothesis that the exact mechanism of the all metabolism in the body, can be result of low magnectic fields occuring by the electrical actions. In the experimental studies healing of the bony defects by the means of electromagnetic fields are well discribed. In our study we evaluated the effects of electromagnetic fields in the haling bony defects with the literature findings between the years 1974-2006.
