Minimal iliac bone harvesting in sinus lift surgery.
For sinus grafting, the authors propose a minimal posterior iliac bone harvesting, with local anesthesia. Autogenous bone grafting continues to be considered the gold standard for sinus grafting. The classic harvesting sites are calvarial, anterior iliac, and tibial, and harvesting is usually practiced under general anesthesia. We performed this technique in 7 patients under local anesthesia. In the posterior iliac crest, with a specific trocar for bone puncture biopsy, bone was harvested. We performed 1 cm longer for 5-mm diameter of bone. Three bone biopsies were harvested on each side. The harvested cancellous bone (5 cm(3)) was mixed with triphosphocalcic (TCP) material (2 cm(3)), and blood (1 cm(3)). A classic sinus lift was realized. After 6 months, the success rate of bone grafting was 100%. Each of the 7 patients could be implanted by an average of 4 dental implants by superior maxillary. For sinus lift, this simple posterior iliac-bone biopsy harvesting under local anesthesia is very comfortable for the patient and also safe. It provides enough marrow bone to be mixed with TCP for a sinus lift.
