Described below are the fol- lowing individual steps, which consist of: 1. Order preparation 2. Scanning 3. CAD construction 4. Preparation for manufacture 5. Manufacturing 6. Completion Orderpreparation:30seconds First, the practitioner, the pa- tient and the respective tech- nician are defined in the order entry form. The second step consists of the definition of the indication including all param- eters. In the present case, this concerns the creation of two full crowns to be made of Vita ENAMIC Regio 46 and 47. The parameters for the respective practitioner can be referenced in the KaVo multiCAD soft- ware. This function guarantees consistent quality regardless of the originator of the order (Fig- ure 1, 2). Scanning: 180 seconds This case is scanned with the new fully-automatic ARCTICA AutoScan. The scan process is very simple as the software guides the user step by step through the scan process. The individual scans are performed completely automatically. First, the upper jaw is scanned, fol- lowed by the lower jaw. If nec- essary, single stumps may then be scanned separately. This is Figure 1 Figure 4 Figure 7 Figure 8 Figure 9 Figure 5 Figure 6 Figure 2 Figure 3 followed by a vestibular scan allowing the correct position- ing of the jaws by the software Figure 3. The next step consists of matching the individual jaw scans and the vestibular scan by marking three identical points on the respective jaw and vestibular scan. After- wards, the software calculates the exact position of the upper and lower jaw scans(Figure 4, 5, 6). Construction of the restora- tion in the KaVo multiCAD software: 180 seconds In the KaVo multiCAD soft- ware, the contact relief of the corresponding jaw is displayed in the scan software. For analytical purposes, it may be displayed in color. The re- spective color and intensity indicate the distance to the an- tagonist. Afterwards, the articulator KaVo PROTAR evo 5B is started in the KaVo multiCAD software. The respective patient-specific settings of the physical PRO- TAR articulator such as, for ex- ample, the condyle track incli- nation and the Bennett angle, are entered into an entry mask. The correct positioning of the models in the virtual articula- tor (KaVo PROTAR 5B) is done automatically. Based on the scan of the articulated models in the ARCTICA AutoScan and the positioning of the models by the KaVo Splitcast system, the correct positioning is au- tomatically transferred to the CAD software. This positioning also applies to models that were inserted into the articulator by means of a facebow. After the adjustment of the pa- tient-specific parameters, the motion tracks are simulated and any interferences are cor- rected by the software (Figure 7, 8, 9). The illustration shows a lat- erotrusion to the left (Figure 10). In the subsequent construction process, the movements of the jaws may be visualized at any time (Figure 11). The manufacture of the two VITA ENAMIC crowns on 46 and 47 is performed quickly and easily by means of library teeth that are automatically po- sitioned onto the preparations and may be loaded into the situ- ation via a simple mouse click. Furthermore, the library teeth may subsequently be matched to the individual occlusal relief of the chewing surface. The user is able to adjust the sug- gestions of the software via a wizard (step-by-step assistant) at any time during the con- struction process.
