I case report _ smile design & CAD/CAM intraoral scanner (Figs. 10 & 11). Both the upper and lower arches were scanned and the digital im- pressions were immediately available for wax-up designing. The smile design silhouette was exported from the smile design software to the CAD software for wax-up designing (Fig. 12). The silhouette was ad- justed on top of the digital impression and used as a guideline for creating veneer designs in the soft- ware. The tools in the CAD software were used to design and finalise the digital wax-up (Fig. 13). Next, the digital wax-up was 3-D printed for mock-up creation. A silicone key was prepared from the 3-D printed model. Using the silicon key andthe3MESPEProtemp4TemporisationMaterial, a mock-up was created into the patient’s mouth (Fig.14),withitsfitandfunc- tionality checked. At this point, the patient had the opportunity to experience the design of her new teeth and understand the altered feel and look (Fig. 15). _Preparations and temporary veneers After confirming the proper fit, the patient’s teeth wereprepared(Figs.16&17) and the preparations were scanned, again using an in- traoral scanner. Next, tem- porary veneers were created with the same silicon key and 3D ESPE Protemp 4 Temporisation Material. The temporaryveneersweretried on the patient and fixed by spot-etching. 40 I CAD/CAM 1_2016 Fig. 16 Fig. 17 Fig. 14 Fig. 15 Fig. 12 Fig. 13 Fig. 9 Fig. 10 Fig. 11 CAD0116_38-41_Linden 21.01.16 11:16 Seite 3 CAD0116_38-41_Linden 21.01.1611:16 Seite 3
