[Maxillofacial prostheses on endosseous implants. Various modes of fixation].

Both mechanical and magnetic types of fixation can be used with extra-oral implants, with the possibility of positioning maxillofacial prostheses by either mechanical, magnetic or mixed fixation, the latter by a combination of the two methods. These different modes of fixation allow precise positioning, avoid the use of adhesives, limit maintenance problems and, in addition, facilitate oncologic surveillance, providing a non-negligible complement to reconstructive surgery.
