Since the idea that electricity is the most basic element in sustaining human life was introduced, many researches and theories have been developed. Over the past forty years, experiments on cells, animals, and human beings have been carried out with currents or electromagnetic fields. The experiments contributed to facilitating the formation and growth of bones. Uncertainties still remain, however, since a number of complex and interrelated factors are involved in the mechanism of bone formation. At present, electricity, supersonic waves, and radio frequency are being used to facilitate bone formation and successfully treat bone fractures. This fact leads to the assumption that such methods could be utilized to induce and promote the formation of bones around an endosseous dental implant. Previously conducted experiments have already recognized the possibility. However, there are things to consider before making the approach. They are: Is the devise to be used designed small enough to function effectively in the mouth? What kind of impact does energy have on adjacent tissues? Can energy be supplied ceaselessly? How long should a stimulus be given? Regarding an implant, the material of it as well as the characteristic of its surface will be significant factors.
