Purpose: The purpose of this follow-up study was to quantify the change in the periimplant mucosal level after treatment of edentulous patients with fixed prostheses on osseointegrated endosseous implants. Materials and Methods: Twenty patients were included in the study: 10 were treated in the maxilla, and 10 were treated in the mandible. Both groups had fixed prostheses on osseointegrated Brånemark implants. Periimplant mucosal level was measured with a calibrated probe after removal of the prostheses at the 1-year follow-up. These measurements were compared to those made on the original master casts. Results: A larger mean retraction (–) was observed in the mandible (–1.6 mm) compared to the maxilla (–0.8 mm), but there was great variation. The individual values varied from –4.5 to +1.0 mm in the mandible and from –6.0 to +6.0 mm in the maxilla. Conclusion: Peri-implant soft tissue recession occurs during the first year in edentulous jaws after treatment with implant-supported fixed prostheses and more so in the maxilla than the mandible.
