An Electronic System IC for Enhancing Bone Formation in Dental Implant

Abstract

This paper presents an electronic device for enhancing osseointegration of surrounding tissues in dental implant. Early bone formation between implant surface and surrounding tissue is very important to shorten period of treatment as well as decrease failure rate of implant surgery. In order to accelerate bone formation, we designed a biphasic electrical current (BEC) stimulator IC, having parameters of 20uA/cm2, 120us-duration and 100 pulses per second. It was integrated with micro-batteries in temporary healing abutment and the system operated for 7 days with continuous BEC stimulation in animal tests. The results of animal tests show that the proposed electronic system expends the osseointegration of the implant surface by 1.69-fold more than that of the controls. Based on these results, we proposed new electronic system that could be applied to accelerate bone formation in dental implant. These technologies also can be used to the patient with osteoporosis.
