summary  The aim of this study was to evaluate the success of one‐stage implants placed at the time of alveolar bone augmentation using simultaneous guided bone regeneration technique with a collagen barrier membrane in patients suffering from insufficient bone width. Seventeen patients were treated with 20 one‐stage OSTEOFIX (Oulu, Finland) implants using simultaneous guided bone regeneration technique. Dehiscence defects were filled by bovine bone mineral Bio‐Oss® and covered with collagen membrane. Clinical and radiographic parameters of the peri‐implant conditions were assessed at the moment of prosthesis placement and at 1‐ and 5‐year follow‐ups. Diagnostic dehiscence defect measurements after implant placement showed that the mean vertical defect varied from 3·8 mm to 10·0 mm. At the moment of prosthesis placement and at 1‐ and 5‐year follow‐ups all implants were stable, painless and without biological complications. Clinical and radiographic parameters of the peri‐implant conditions remained stable during follow‐up. The cumulative implant survival rate was 100% after the 5‐year observation period and the success rate for all pooled implants was 90%. The present study showed predictable treatment outcomes recorded after 5 years of function for one‐stage OSTEOFIX (Oulu, Finland) oral implants placed simultaneously with guided bone regeneration using collagen membrane and deproteinized bovine bone mineral.
