The study is a controlled randomised study whereby each patient will receive 5-6 implants placed in the edentulous upper jaw supporting a 10-12 unit screw-retained fixed partial denture (FPD). The main objective of the study is to evaluate the performance of Straumann implants supporting a FPD using Straumann Implants and Cresco restorative components in early and delayed loading protocols at one year post-loading. The treatment groups consist of an early loading and delayed loading arm using Cresco restorative components loading time 10 days post surgery and at 6-8 weeks respectively. The control group comprise the standard delayed loading protocol (healing period 6-8 weeks) and Straumann restorative components. The primary objective is to compare changes in crestal bone levels on radiographs between implants in the control group and test groups at 1 year.The patients will be followed for 3 years.
