- 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.
