Only a few years ago, the idea of using CAD/CAM to fabricate removable dentures seemed scarcely realistic even though such technologies had already become an indispensable component of the work- flow for fixed superstructures on natural teeth and implants. Recently, digital tools that help to provide rapid and predictable treatment of edentulous pa- tients have become available. This report describes a digital system (Digital Denture System, Wieland Dental) that allows complete dentures to be pro- duced in only three appointments. A 70-year-old female patient wearing a complete maxillary denture had suffered an avulsion of the anterior mandibular teeth four weeks prior to her first visit. Lack of support in the posterior mandibu- lar region and continued pressure in the anterior maxillary region had led to severe atrophy. The clinical situation was therefore akin to the dental condition described as combination syndrome (Figs. 1a–c, 2a&b). Since the patient wanted a rapid and cost-effective rehabilitation with removable dentures, we opted for the Digital Denture System protocol. First appointment For the preliminary impression, a prefabricated impression tray was coated with a tray adhesive (Virtual Tray Adhesive, Ivoclar Vivadent) and the impression material was mixed with the catalyst (Virtual Putty Regular Set, Ivoclar Vivadent).
