Development of a Biphasic Electrical Current Stimulator for Enhancing Early Bone formation in Dental Implant

In dental implant, early bone formation of surrounding implant surface has long been key technology to increase success rate. In this study, in order to enhance bone formation, we stimulated biphasic electrical current with 20μ A/cm2 through temporary healing abutment to a surrounding bone tissues. Developed small sized biphasic electrical current stimulator was integrated in temporary healing abutment with power source and the device was applied for 7 days in early stage of osseointegration in animal experiments. 서
