The Software-Module Prettau® is a tool for the manufacture of fully anatomical works. It enables the exact reduction of the fully anatomical modelations as the basis for a evenly strong ceramic layering. By doing this, it minimizes the danger of ceramic chipping. With the Software-Module Prettau® you have a greater freedom of design in case of restricted spaces and in combination with the specially developed coloring technique for full zirconia bridges without ceramics, a Prettau® bridge can be manufactured.
