Simultaneous implant placement in sinus floor augmentation using iliac bone block grafts in severe maxillary atrophies: case report.

The placement of implants requires adequate basic conditions. Insufficient bone height and width in the area of the maxilla, because of expansion of the maxillary sinus and atrophic resorption of the alveolar ridge, represent a common anatomical complication, which can be solved by augmentation of the floor of the maxillary sinus. It is commonly shared that autologous bone graft is the gold standard method in the augmentation of the Higmoro antrum. The reconstruction of atrophies with adequate bone volume and density has become a viable treatment option with high predictability and success rates. The purpose of this study was to present the results obtained with a surgical procedure aimed at reconstructing (rehabilitating) advanced maxillary atrophies. This method includes the use of intramembranous, corticocancellous bone grafts harvested from the iliac crest. These are then fixed to the residual bone by endosseous implants.
