[The interdisciplinary fixed restoration of an edentulous maxilla with a pronounced resorption of the alveolar crest. A case report. Part I: The immediate reconstruction]

Edentulous patients wearing a conventional complete denture often request a fixed restoration for functional, esthetical and/or psychosocial reasons. For these patients implant-supported fixed dental prostheses are a prosthetic means of choice. However, after years of edentulism often a marked resorption of the alveolar crest has taken place, asking for bone augmentation before implant placement. Thus, fixed implant reconstructions are time and cost intense and stressful for the patient. This case report documents the immediate fixed reconstruction in the edentulous maxilla after ridge augmentation with a cortical cancellous bone graft from the iliac crest and implant placement. A CAD/CAM-system was used for implant planning and the fabrication of a drilling guide. The prosthetic reconstruction was inserted immediately after implant placement.
