I 31 industry report _ digital technologies I CAD/CAM 1_2015 pre-visualization using the prototype (Fig. 24). The prototype is also very important for the dentist in order to check the relationship between the teethandlips(intermsofaesthetics,phoneticsand support of the soft tissue). After this step, according to the volumes obtained, the framework to support the acrylic teeth was constructed in DentalCAD (Figs. 25a & b). Our goal was to create a framework in titanium by reducing the prototype on which the teeth were to be placed—exactly as planned in DSS. We created and submitted the CAM file for order pro- cessing through software integrated into DentalCAD. After the milling cycle (fourth step of the digital dentistry workflow), the product was carefully adapted to the model in order to finalize the work. In particu- lar, the titanium framework was prepared and the acrylic teeth positioned using a verticulator (Fig. 26). By means of these new digital technologies, the dental technician is given the opportunity to express and enhance his or her skills and creativity by focusing on finalization of the aesthetics and functionality. As can be seen, the final result is perfectly in accordancewiththescheduleestablishedwiththe patient during the first step of the digital dentistry workflow (Figs. 27 & 28). Following a precise workflow, the protocol covers all stages of the project, from the material choice to the production and finalization, aiding the work of both the dentist and dental technician and providing several new benefits to the patient too. _Conclusion This article clearly demonstrates the precise working protocols provided by digital technologies and the reason they are being increasingly im- plemented in daily work in dental practices and laboratories. In particular, it has shown how the use of 3-D scanners and dedicated software is becom- ingpartofthedigitalworkflowindentistry.Itallows a complete aesthetic and functional preview of the final result and facilitates working in CAD with very accurate data. The digital dentistry workflow presented with this particular example has shown that the benefits arising are not limited to the work (a time and cost saving, as well as more accurate results), but also extend to the patient, who is given a reliable preview of the treatment outcome._ Massimiliano Rossi is a CAD/CAM specialist and dental technician working for EGS.
