A 42-year-old male patient presented with severe periodontal disease requiring extensive vertical bone augmentation (VBA) prior to implant placement. Following tooth extraction and periodontal treatment, VBA was achieved using a xenogeneic graft and stabilized with a native bilayer collagen membrane and fixation screw. Owing to the limited volume maintenance of the resorbable membrane, the implant was installed with reinforcement using a sinus crestal approach. Over an 8-year follow-up period, the implant exhibited stable alveolar bone without signs of peri-implantitis or significant bone resorption, suggesting the efficacy and longevity of this technique.
