A 59-year-old patient in good general health presented with advanced peri-implantitis at site 1.3, leading to the removal of the implant. Twenty days later, a three-dimensional reconstruction of the alveolar ridge was performed using the Sausage Technique, with simultaneous placement of a new implant. The bone defect was regenerated using a 1:1 mixture of autologous bone and collagen-preserved cortical-cancellous granules, stabilized by an equine pericardial membrane secured with osteosynthesis pins. At five months, a connective tissue graft was performed and the abutment was placed to optimize the soft tissues; after six months, the final prosthesis was delivered.
