Abstract

A case is reported of a 66-year-old woman who could not use a conventional, full upper denture because of a gag reflex. In the maxillary alveolar ridge, restoration was performed on a moderately atrophied, edentulous anterior area and a small defect in the right-side posterior area. In the mandibular alveolar ridge, restoration was performed on a moderate osseous defect in each molar area resulting from tooth extraction due to severe periodontal disease. Based on careful treatment planning, four types of bone graft were used with previously designed osseointegrated implants. The atrophied maxillary alveolar ridge was restored with veneer iliac bone grafts to avoid fenestration during implant placement, while alveolar process deficiency was restored using inlay and sinus bone grafts as placements for long implant fixtures. The defects in the mandibular alveolar bone were filled with corticocancellous bone chips at the implant placement sites. A combination of immediate and secondary placement of Brånemark fixtures was used. Bone-anchored bridge-type implant prostheses were fitted approximately twelve months after surgery. Three years later, there had been no failure of implant fixtures and satisfactory functional and cosmetic restoration had been maintained.
