Abstract
We performed dental implant treatment following autogenous bone graft from the iliac bone to the sinus floor for a 68-year-old male patient with severe atrophy of the posterior maxilla. After bone grafting, the sinus floor was lifted up 10 mm to 15 mm. On the 14th day after the operation, fracture of the iliac crest occurred accidentally. An avulsion fracture of the anterior superior iliac spin at the lower part of the donor site was diagnosed. We treated the fracture conservatively, and after four weeks, the patient recovered to be able to go up and down the stairs. Four months later, four implants were inserted in the bone grafted area.
For patients with severe atrophy of the posterior maxilla, sinus elevation with iliac bone harvesting is considered to be an effective method. However, there are possible complications associated with iliac bone grafting, such as in this case. Therefore, careful management after such an operation is necessary.
