To restore masticatory function, dental implants require adequate bone support. For extensive maxillary bone loss, sinus lift surgery with bone grafting is often employed, favoring the autogenous iliac crest bone for better implant integration. Guides aid in the precise placement of implants and can reduce surgery time. In this context, an approach that combines of sinus lifting, bone grafting, and implant placement can be beneficial. In April 2020, a 58-year-old male presented with severe left maxillary alveolar bone atrophy and peri-implantitis of the right maxilla. Implants #15i, # 16i, and # 17i were removed, followed by bilateral sinus lift, bone grafting, and implant placement. During the 2-year follow-up after prosthesis placement, both the graft material and implants remained stable without complications. Iliac bone grafts exhibit greater resorption than other graft materials. In this case, implant positioning based on virtual planning and modifications guided by experience was performed without complications.
