Purpose: The purpose of this clinical follow‐up was to document the 7‐year outcome of immediately loaded implants exhibiting an oxidized surface. Material and Methods: Thirty‐eight patients received a total of 51 implant‐supported fixed prostheses. The restorations were supported by 102 implants, the majority of which were placed in posterior regions (88%) and primarily in soft bone quality (76%). Radiographic examinations were performed at prosthesis insertion, at 1‐ and 6‐month follow‐ups, and annually at the 1‐ through 5‐year follow‐up visits. Marginal peri‐implant soft tissue evaluations were conducted at all these follow‐ups. This report presents the results after at least 7 years of loading. Results: After 7 years of prosthetic loading, the cumulative implant survival rate was 97.1% and the mean marginal bone remodeling was −1.51 mm (SD 1.00, n = 73) with significantly more initial remodeling at sites having received marginal guided bone regeneration procedures. A low rate of biological and technical complications was detected after 7 years of function. The quantification of intrasulcular plaque sampling showed no significant difference between teeth and implants. Conclusion: The 7‐year follow‐up data indicate that the introduced immediate loading protocol is a successful treatment alternative also including regions exhibiting soft bone conditions.
