Abstract In order to anchor implants in the severely atrophic maxilla, the method of sinus floor elevation has been introduced about ten years ago. For this purpose the bony support is extended into the sinus floor by filling it up with bone graft. It was not clear yet which degree of maturation the augmented bone must reach to distinctly reduce stress peaks in the bony structures. The results of this FE‐study show that it seems to be essential for the bone graft to attain at least the stiffness of cancellous bone. (© 2004 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
