Objective: Atrophic posterior maxilla may pose a significant challenge for dental implant treatment. Various treatments are available for augmentation of the vertically defective. Segmental sandwich osteotomy is an alternative option for dental implant treatment that provided reconstruction of the bone defect (1,2). In recent years, iliac bone grafting has become one of the most widely used autogenous bone grafting techniques (3). In this case, we present segmental sandwich osteotomy with interpositional iliac graft for the treatment of vertical bone defect. Case: A 67-year-old male patient has been admitted to our clinic for dental implant treatment. As a result of radiographic and clinical examination, it was seen that the vertical bone volume was insufficient in the left maxillary and right mandibular areas where implants were planned (Figure 1). Segmental sandwich osteotomy with interpositional iliac graft planned for the treatment of vertical bone defect. Iliac bone harvesting were performed under general anesthesia (Figure 2, 3). Segmental osteotomy was performed in the left maxillary posterior region. The iliac graft was placed in the interpositional region and the plate was fixed using screws (Figure 4). The iliac graft was fixed to the right mandibular region with a screw and plate (Figure 5). Implants were placed at 6 months post-operative (Figure 6,7,8). Conclusion: Studies have shown that segmental sandwich osteotomy is a relatively simple technique that provides surgical success and a high level of predictability(4). In the treatment of moderate to severe vertical alveolar bone loss, segmental sandwich osteomies with iliac grafts can show successful results. Keywords: dental implants, iliac graft
