Are there rejection problems with dental implants?
It has been scientifically demonstrated that in carefully controlled condictions, titanium can become 'integrated' into living bone without causing any type of inflammation to the surrounding tissue. This process in which the bone cells connect with the surface of the titanium is called osseointegration whereby the bone accepts the titanium as if it formed a part of the body, producing a "biological weld" and growing around it. It is important not to confuse rejection with the possible complications.
At present, the success level (osseointegration) of implants stands at around 99%.
