The work to be manufactured and the predefined material to be used may be reviewed in a 3D view. If necessary, additional modifi- cations such as, for example, a change of the material may be made. After the selection of the KaVo ARCTICA engine as the produc- tion machine and a VITA EN- AMIC for KaVo ARCTICA block, which was previously booked into the KaVo CSS via RFID technology, the nesting, i.e. the positioning of the restoration in the virtual material block, may be performed (Figure 18). Figure 18 Figure 22 Figure 23 Figure 24 Figure 25 Figure 19 Figure 20 Figure 21 Production on the KaVo ARC- TICA engine: 25 minutes per crown Now, the blanks are inserted in the block bracket of the ARC- TICA engine and affixed with a torque wrench with a defined tightening torque (Figure 19, 20, 21). Afterwards, the tool stack with the tools required for the Vita ENAMIC - in this case, 4 different grinding tools with di- ameters between 0.6 – 3.6 mm - is inserted. These tools were also previ- ously booked in the KaVo CSS software via RFID chip and assigned to the glass ceramic tool stack. The advantage is that the tool service times are precisely logged and that the ARCTICA engine uses a traf- fic light pattern (green, yellow, red) to show the user when a tool should be exchanged. This also helps to minimize applica- tion errors. In case of an automatic tool change in the KaVo ARC- TICA engine, the tools are once again inspected with a laser for breakage or faulty positioning once they have been removed from the stack. The processing is started at the touch of a button on the touch-screen of the ARCTICA engine or, alternatively, direct- ly at the PC (Figure 22). Completion of the VITA EN- AMIC crowns: 180 seconds each After the succesful produc- tion of the two restorations on the KaVo ARCTICA engine, the VITA ENAMIC crowns may be separated from the material block. The ARCTICA engine may be connected to a KaVo lab handpiece (ERGOgrip and POWERgrip) and used to fur- ther process the works. Prior to the start of the grinding proce- dure, there is also an opportu- nity to reduce the diameter of the connectors to a minimum at the end of the production process, so that the time ex- pended for the separation of the restoration becomes negligible. After the grinding pro- cedure, the VITA ENAMIC crowns are polished in a time- saving manner with the tools from the VITA ENAMIC pol- ishing set. An additional sub- sequent individualization of the work is possible with the colours of the VITA ENAMIC stains kits. In this case, an ad- ditional individualization was omitted upon the request of the patient (Figure 23, 24, 25). Thanks to the use of the vir- tual articulator during the con- struction in the KaVo multiCAD software and the precise 5-axle technology of the ARCTICA en- gine, the work could be insert- ed directly into the mouth of the patient and corrections of the occlusal relief could be waived. As can be seen, precisely inte- grated process chains pay off.
