Biphasic electrical current stimulator for early bone formation in dental implant

Abstract

Since the discovery of piezoelectric properties of natural bone, electrical stimulation has been widely used in the clinical treatment of orthopedic fracture. Nevertheless, in dental implant technologies, it is the methods of surface modification that has been recently developed to enhance early osteointegration between implants surface and surrounding tissue. In this paper, in order to accelerate bone formation, we developed a battery powered biphasic electrical current stimulator integrated in healing abutment of dental implant. In vivo. animal test shows that the proposed electrical stimulation system expends the osteogenesis of the implants surfaces by 2.15 times more than that of controls. Based on these results, we propose novel dental implant technology that can be applied to patient with osteoporosis.
