[Factors of failure of prosthetic restoration of the acquired losses of substance of the jawbone and the mandible in sub-Saharan Africa]. / Facteurs d'échec de la restauration prothétique des pertes de substances maxillaires et mandibulaires acquises en Afrique subsaharienne.

The obturating prostheses of the jawbone and the prostheses of rebuilding of the mandible make it possible to restore the losses of substance of the jawbone and of the mandible and to cure the functional and Aesthetic disorders which result from these losses of substance. The success of these prosthetic restorations can be compromised by technical, economic and cultural factors. The principal factors are the importance of the losses of substance, the reduced number of teeth, the poverty of the technical plate, the persistence of certain traditional concepts. The fight against these factors requires the promotion of therapeutic associations in maxillo-facial cancerology, the sensitizing of the populations to the early hospital consultations, the improvement of the technical plate of the prosthesis of the jawbone and the face, the facilitation of the access of the most underprivileged groups to the prosthetic restorations, the promotion of multi-field collaboration, the whole co-operation of the patient throughout the treatment and the follow-up postprothetic.
