The Unknown Process Osseointegration [PDF]

Biology, 2020
Although it was already described more than fifty years ago, there is yet no in-depth knowledge regarding the process of osseointegration as far as its mechanism of action is concerned. It could be one of the body’s ways of reacting to a foreign body, where the individual’s immune response capacity is involved.
