- Bone grafts from the hip in combination with Brånemark self-tapping fixtures have been used to rehabilitate patients with extremely resorbed maxillae. Experiences and results from the first ten consecutive cases have been analyzed to form the basis for further use of the method. Eight of 57 fixtures placed have been lost to date. Surgical complications, including exposure of the bone transplant, have occurred in three patients. The method should be used with caution, and cases should be meticulously chosen to exclude those who do not have proper motivation to endure the long-lasting and demanding surgical and prosthetic procedures required. The combined use of implants and transplants should not be used routinely until a long-term evaluation of the method and results has been made.

- A combination of horseshoe-shaped iliac bone grafts and Brånemark implants was used in 30 patients with severely resorbed maxillary alveolar ridges. All patients were followed clinically for 2 years and evaluated with regard to prosthesis stability, fixture survival, wound healing complications, and soft tissue conditions. Surgery was performed by the same oral surgeons using identical procedures, and the prosthetic treatment was performed by the same prosthodontist. The development group included the first 10 patients and the routine group included the following 20. Fixture survival in the development group was 54.4%, whereas 88.3% of the fixtures in the routine group have survived after 2 years. The average fixture survival in the study was 77.4%. Three patients in the development group lost all fixtures, primarily the result of trauma to the grafted region. With respect to the difficult situation many of these patients experienced, the survival rate should be considered most acceptable.

- One of a series of patients with extremely resorbed maxillae treated with bone grafts from the hip in combination with Brånemark self-tapping fixtures died in a car accident 4 months after implant surgery. Autopsy specimens from this patient were analyzed to evaluate the amount and extent of "osseointegration" after 4 months of healing. Histologic examination revealed that minimal bone was in direct contact with the titanium and the general pattern was that of soft tissue screw anchorage. There were no signs of sequestering of the transplanted bone. The connection between the nasal cavity and the sinus mucosa with respect to the transplants seemed to be without adverse reactions. The superior part of the transplant did show signs of newly formed bone. The grafted specimens showed indications of delayed bone response compared to the nongrafted situation. All implants were clinically stable as studied postmortem.
