dc.description.abstractA dental implant is a unique structure which can be used with a noninvasive method because it is
inserted into the bone in part and extended extracorporally. This study presents an electronic device
that is temporarily connected with the dental implant, and reports its effect on accelerating bone
formation in the surrounding tissues in a canine mandibular model. A small sized and low power
consumption biphasic electrical current (BEC) stimulator ASIC was developed and the surrounding
tissue was exposed to continuousBECstimulation for 7 days with the parameters of 20 mA/cm2, 125 ms
duration, and 100 pulses/s. After 2 (n¼5) and 5 weeks (n¼5), animals were sacrificed and the
specimens were histomorphometrically evaluated. The newly formed bone area (BA) was 1.30 times
(3 weeks, P<0.05) and 1.35 times (5 weeks, P<0.05) higher in the experimental group compared to
the control group, respectively. Bone-implant contact (BIC) in 3-week specimens was 1.62 times
(P<0.05) greater in the experimental group, while there was no statistically significant difference in
5-week specimens. Based on these results showing accelerated bone formation on and around the
dental implant, it could be suggested that the latent time for osseointegration in dental implants can be
reduced, and the success rate of implants in poor quality bone can be increased by using our device with
BEC.
