The problem of insufficient alveolar bone in the edentulous maxilla caused by resorption and pneumatization can be overcome by augmentation of the sinus floor to increase bone volume for the placement of dental implants. The quality of bone which is achieved after sinus floor augmentation is hardly known. This study describes the histologic results obtained three till six months after sinus floor augmentation with autogenous bone from the iliac crest in patients with severe maxillary bone resorption. The bone biopsies taken from the implant sites showed a substantial bone volume with a mature trabecular pattern and active bone growth. It was concluded that with the obtained bone quality, the sinus floor augmentation procedure can be a good treatment modality for the rehabilitation with implants in patients with severe maxillary bone atrophy.
