Purpose: The aim of this report is to quantitatively and qualitatively describe the bone tissue response to Brånemark implants retrieved from grafted sites in patients. Materials and Method: The material consists of consecutively received Brånemark implants retrieved from grafted sites. Thirty‐five of these implants, retrieved from 16 patients, were suitable for the histologic evaluation of undecalcified sections in the light microscope. Results: The unloaded implants were mainly lined with soft tissue, and sparse bone‐implant contact was observed only in some sections. The loaded implants, with the exception of one implant removed due to mobility, had mature and new bone‐implant contact. Resorption of graft through cutting cone structures was detected. Cement lines were found separating bone‐like tissue albeit no cellular content and bone tissue with detectable osteocytes. Conclusion: In this heterogeneous group of implants from grafted sites, the unloaded implants showed limited bone‐implant contact. The autografts showed seemingly mixed viability as judged by the cell content in the osteocyte lacunae and cement lines separating areas with filled and empty lacunae.
