Severe alveolar atrophy and anatomic limitations make the construction of an implant supported fixed prosthesis impossible without advanced surgical procedures. The purpose of this case report is to present the reconstruction of severely atrophic maxilla with autogenous iliac crest bone graft and subsequent 4 implant supported fixed zirconia dental prosthesis. The clinical examination of an otherwise healthy 61-year-old woman, referred with the requirement of a fixed prosthesis, revealed an edentulous maxilla except a single tooth and bilateral posterior edentulous mandible. Total maxillary alveolar crestal augmentation and bilateral maxillary sinus grafting were performed with autogenous corticocancellous iliac bone graft harvested under generla anaesthesia. Following the graft consolidation period, 4 implants were inserted in the maxilla while 2 and 1 implants in the mandible to the right and left respectively. After 4 months, implant supported fixed zirconia prosthesis were reconstructed for the maxilla and mandible. The patient’s aesthetic and functional expectations were achieved immediately. At one-year follow-up no aesthetic, biological, functional and biomechanical complications were observed.
