Abstract:

A dental implant employs electrical bone growth stimulation by incorporating a galvanic cell in the implant. The implant is formed as a machine screw made of titanium. The machine screw contains an internal threaded portion for accommodating a cap screw to cover the top of the implant. Within the hollow portion is pressed a small aluminum rivet which makes intimate contact with the titanium implant. This forms the anode of the cell which will become the negative electrode of the battery. A slug of silver chloride is fastened to a cover screw. A saline solution is used as the electrolyte. Once activated, the reaction consists of the reduction of silver chloride to metallic silver. The slug of silver chloride forms the cathode of the cell and becomes the positive terminal of the battery.
