After removal of all teeth in grown up mini-pigs, extension implants were anchored into the dental area of the lower jaw and connected to a battery unit, one implant always forming the cathode and the other the anode. Clinical, radiological and histological results show completely different reactions of the implant site. In the region of the anode there occurs osteolysis which results in considerable looseness of the implant. The implants used as cathodes are clinically firm and when compared to implants not stimulated show increased bone regeneration.
