RESUMO
The combination of scanning technology and CAD/CAM procedures allows to significantly reduce working time clinically as well as for the dental laboratory. In comparison to conventional complete denture fabrication, the AvaDent® system provides specific trays and registration plates to complete all the required patient recordings and steps in the first appointment. By virtual modeling (CAD) and milling of the denture (CAM) out of a solid acrylic puck, time-consuming flasking and packing procedures are needless. Due to the abscence of any polymerisation shrinkage of the dentures, the precision of fit remains accurate. This system allows to efficiently deliver high-quality and cost-effective complete dentures for the edentulous patient in only two appointments. The clinical procedure is presented step-by-step and critically evaluated from the clinicians point of view.
RESUMO
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.
