Abstract
A method and apparatus for accelerating osseointegration of titanium implants in bone to anchor a prosthetic or dental device thereon in which an alternating electric signal of symmetrical wave form and of substantially constant amplitude having a frequency in the range of from about 40 to 100 KHz and providing a constant current in the range of from about 10 to 100 microamperes is supplied to at least one electrode in contact with the metal implant and another electrode in contact with the skin in proximity to the implant.
