Devenir des implants après chirurgie préimplantaire

Summary Introduction The purpose of this study was to evaluate the implant placement outcome in edentulous patients prosthetically rehabilitated after autogenous bone graft. Materiel and method Between 2002 and 2006, 75 patients underwent graft surgery, only 64 patients (mean age of 53.8 years) had a complete treatment. Calvarial bone grafts were used in 41 cases, mandibule bone in 13 cases, and iliac bone in 13 cases. Grafting techniques were onlay and inlay grafts in the maxilla combined or not with LeFort I osteotomies, and onlay or interposed bone graft in the mandible. Twelve patients presented with complications, wound dehiscence in seven cases and infection in five cases. Twenty-two patients presented with perforation of the sinus mucosa in the course of sinus lift. Results Three hundred and seventy-nine implants were inserted in 64 patients, 295 in the maxilla and 84 in the mandible. Fifteen implants failed (3.95%), 13 before loading and two after, 10 maxillary implants (3.38%), and five mandibular implants (5.95%). The global implant survival was 96.05% with a mean background of 23.6 months, 88.37% after sinus lift, 83.33% after apposition graft in the mandible and 88.64% in the maxilla. Discussion These results correlate to current published data.
