In patients with biltareral edentulous areas and resorbed alveolar processes in the maxilla a bilateral sinus augmentation with Bio-OssTM, CE certified (Geistlich Biomaterials, Wolhusen Switzerland) will be performed. In one side additionally autogenous stem cells, that were harvested from the proximal tibia 2 months before and cultivated over 2 months in vitro, will be applied in the test sinus. Histomorphometric analysis will be performed with Biopsies after 3 and 6 months.
