[Maxillary pre-implant rehabilitation: a study of 55 cases using autologous bone graft augmentation].

Preprosthetic rehabilitation of the maxillary bone is sometimes difficult due to severe bone resorption in the posterolateral regions. The sinus lift with autogenous bony graft has given us satisfactory results since 1990 but requires a rigorous protocol before and during surgery to assure a lasting anchorage to the prosthesis. We describe morbidity and technical choices of this intervention in a series of 55 patients.
