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.
