summary In a controlled clinical trial, treatment effects of mandibular overdentures on two different implant‐systems in edentulous patients were compared one year after insertion of the new dentures. The implant‐systems used were the Brånemark system (Brå) and the IMZ‐system. Treatment was randomly assigned to 60 patients according to a balanced allocation method. Evaluation included peri‐implant and radiographical parameters. According to the Delphi method a clinical implant performance scale (CIP) was constructed based on all conceivable complications of the different implant systems. During the osseointegration period, five Brå‐ and one IMZ‐implants were lost. The results of one of the peri‐implant parameters and the radiographical score showed significant differences considering the (pseudo) pocket probing depth (Brå better than IMZ, P < 0.001) and the radiographic‐score (IMZ better than Brå, P < 0003). The results for the CIP‐scale were less favourable for the Brå‐group than for the IMZ‐group; however, these differences were not significant.
