Abstract

To evaluate preliminary clinical, radiological andhistological result using fresh frozen cortico-cancellous blockallograft in combination with Le Fort I osteotomy for preprosteticsurgery.Methods: Since 2007, 5 patients suffering of extremely atrophicjaws bone were selected for repositioning of the maxilla andsinus lift augmentation, prior implant-supported prosthetic rehabilitation.Patients underwent Le Fort I procedure and freshfrozen cortico-cancellous blocks were used as interpositionalallograft. Resorbable double-layer membrane were placed whenon-lay grafts were performed. Harvesting of bone blocks wasperformed from iliac crest of multi-organ donor. Pre-operativex-ray evaluation included a standard x-panoran and CT Dentascan.Immediately before surgery, bone chips were washed withsaline solution at 40ºC in order to de-fat it, and mixed withautologous venous graft. Standard chemio-profilaxis and postoperativetherapy were administer to each patient. Six monthsafter bone grafting a CT Denta-scan was obtained prior implantsurgery. A bony biopsy was performed at the time of implantinsertion to evaluate bone graft osteorigeneration.Results: All surgical procedure were performed without complications.Only moderate swelling and moderate blood loss fromnose during immediate time after surgery were observed. CTDental-scan, performed 5 months after surgery, confirmed noneradiological signs of re-absorbed bone tissue neither periostealreactions. Histological results showed good bone integration withnone tissue necrosis or immunological reactions.Conclusion: Fresh frozen homologous grafts can be consider asvalid substituted bone tissue in maxillo-facial surgery.
