ABSTRACT:
Osteogenesis and osseointegration promotion and maintenance devices for osseous implants include an implant member having a first electrode, an inlaid second electrode positioned on the member so that it is electrically isolated from and substantially flush with the member surface, and an electrical stimulation mechanism preferably located at the member and operative to provide electrical stimulation signals to endosseous tissue surrounding the implant through the first and second electrodes. The first electrode may be the member itself or a second inlaid electrode. The implant is thus electrically functionalized for osteogenesis and osseointgration acceleration. The device is applicable to both non-dental and dental implants. In all embodiments, the use of inlaid electrode(s) enables the general appearance, external surface and mechanical integrity of the implant to be left essentially unchanged.
