[The interdisciplinary fixed restoration of an edentulous maxilla with a marked resorption of the alveolar crest. A case report. Part II: the definitive restoration]

Different materials and methods can be used for edentulous maxillae rehabilitations. A precise fit between the implant and the framework is assumed. Hence, often implant suprastructures made by conventional lost wax techniques lack such a fit and a secondary modification is necessary. Alternatively the CNC-milling technique provides implant frameworks with a passive fit made of titanium and recently also of zirconia. This article describes the fabrication of a fixed complete dental prosthesis supported by seven implants in an edentulous maxilla. Two prostheses were fabricated, one made of a titanium framework veneered with resin and one made experimentally of a zirconia framework veneered with ceramics. The clinical and technical steps are documented and discussed.
