Les défauts maxillo-faciaux peuvent survenir à la suite d'un traumatisme, de troubles congénitaux ou d'une chirurgie ablative, et être reconstruits par chirurgie plastique ou traités par une réhabilitation prothétique. En cas de défauts importants, la réhabilitation prothétique est préférée à la reconstruction chirurgicale en raison des résultats esthétiques insuffisants des interventions chirurgicales. Cependant, la rétention de la prothèse cranio-faciale est un grand problème malgré les résultats esthétiques satisfaisants. Avec la présentation des implants...

Maxillofacial defects may occur as a result of trauma, congenital disorders, and or ablative surgery, and be reconstructed by plastic surgery or treated by prosthetic mean rehabilitation. In case of large defects, prosthetic rehabilitation rather than surgical reconstruction is preferred due to the insufficient esthetic results of surgical interventions. However, retention of the craniofacial prosthesis is a great problem despite the satisfactory esthetic results. With the presentation of extraoral implants, the retention of maxillofacial prostheses was improved and osseointegrated...

Implant rehabilitation in severely atrophied maxillae presents substantial challenges for achieving optimal implant placement aligned with prosthetic goals. This review surveys current literature, encompassing internet sources, manual searches, and standard dental implant textbooks.It emphasizes the critical role of comprehensive knowledge in conventional augmentation procedures, including bone augmentation techniques, guided bone regeneration, alveolar distraction, maxillary sinus elevation with or without grafting, and contemporary implant placement techniques. These approaches collectively...
