Tell 2: Die definitive Rekonstruktion.

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.

Part I: The immediate reconstruction]. / Die interdisziplinäre festsitzende Rekonstruktion eines zahnlosen Oberkiefers mit ausgeprägter Resorption des Alveolarfortsatzes. Ein Fallbericht. Teil 1: Die Sofortversorgung.

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.

[Navigated implant placement using a bone supported CT-guided surgical template. Case report]. / Die navigierte Implantation unter Verwendung einer knochengestützten Operationsschablone. Ein Fallbericht.

Surgical navigation allows precise implant placement and minimizes the risk of interferences with anatomical structures. Computerized implant planning based on tomographic data can be clinically realized by surgical templates. These are normally produced by stereo lithographic rapid prototyping. Accurate placement of virtually planned dental implants depends on a precise fabrication and positioning of the surgical template. Bone-, tooth-, implant-, and/or soft tissue-supported surgical templates allow for different micromovements. This report documents the diagnostics and surgical procedures of implant placement in an edentulous patient. Implant fixed complete dentures in the maxilla and mandible were planned. In the maxilla implants were inserted with the aid of a conventional surgical template. In the mandible a bone supported CT-guided surgical template was used.

A case report]. / Asthetische und technische Aspekte in der konventionellen abnehmbaren Prothetik. Anfertigung einer Totalprothese im Ober- und einer Teleskopprothese im Unterkiefer--Ein Fallbericht]

Removable partial dentures and complete dentures are still an important part of the daily prosthetic work of dentists and dental technicians. Thereby the esthetic design of conventional fixed restorations is challenging the dentist and the dental technician in removable prosthodontics. The result is mainly influenced by the clinical and technical procedure as well as by the choice of material. In this article, the reconstruction of a patient with a complete removable dental prosthesis in the upper jaw and an overlay denture on four telescopes in the lower jaw is presented.
