Brief Summary

Research with DXA has shown the pattern of bone remodelling around an implant. The baseline and reference value for such calculations is the first measurement after the operation. The baseline measurement is performed at different time from study to study. If there is a rapid bone loss the first weeks after an operation, this will influence the reference value and then the results. To evaluate DXA as a method we decided to set up a study with 3 DXA measurements within the first 2 weeks. Our hypothesis is that there is a rapid bone loss the first 2 weeks after operation and that timing of the first post operative measurement will influence the later results.
