[Titanium osteo-integrated fixtures. Otologic applications].
The osteofixtures developed by P.I. Branemark are pure titanium screws implanted percutaneously and intraosseously in the mastoid region. The mechanical properties and biocompatibility towards bone and soft tissues of these titanium fixtures were studied after 80,000 cases of human application, essentially in the field of dentistry. The authors present their preliminary results in the otological field: firstly, the auditory prosthesis with a mean gain of 20 dB over classical prostheses via air and bone transmission and, secondly, the epiprosthesis of the external ear in cases of aplasia with scarred skin.
