Abstract: A medical device and a method for therapeutic treatment within an oral cavity employ a control circuit for generating an electromagnetic field , the circuit including an electrical power source and being integrated in a prosthetic appliance shaped to fit onto a patient's dentition.

Abstract: A dental implant. The dental implant has a body having a top and bottom and parallel sides extending from the top to the bottom. There is at least one opening extending generally diametrically through a lower part of the body. A plurality of discrete, circumferential grooves are formed at the top of the body. The grooves are about 10 to 120 microns wide and about 10 to 100 microns deep. There is an opening in the top to receive a dental receptor. The grooves in the implant prevent cell growth along the length of the implant. Such growth weakens the location of prior art implants.
