Abstract
An improved method of orthondontic electroosteogenesis comprises providing a biocompatible anode having a noble metal portion in engagement with an electrolytic gel portion comprising agarose and an electrolyte, where the anode gel portion is in engagement with epithelial gingiva at an area of osteoclastic or osteoblastic activity, and a biocompatible cathode having a noble metal portion in engagement with an electrolytic gel portion comprising agarose, an electrolyte, and a weak, biocompatible acid, where the cathode gel portion is in engagement with epithelial gingiva at an area of osteoblastic or osteoclastic activity. Electric current is then applied across the anode and cathode to stimulate osteogenesis. The invention also comprises biocompatible electrodes for electric stimulation of tissue.
