Dental Tribune Middle East & Africa Edition | 5/2017 LAB TRIBUNE B3 ◊Page B2 Fig. 24a and 24b: The press technique is also highly effi cient when the restorations are pressed to full-contour and then minimal layers are applied to add fi ne details. Since only a minimum amount of layering ceramic is applied, there is hardly any shrinkage and the results are highly predictable. Fig. 25: The contestants in the conven- tional group brought out the best in the IPS e.max materials. Here, one of the par- ticipants builds up the incisors to full con- tour on IPS e.max Press MO frameworks. Fig. 26: Technical talk: Three members of the CAD/CAM group visit a colleague from the conventional group for a chat. Fig. 27: Checking the length and align- ment of the all-ceramic crowns in the ar- ticulator. The marks on the wax-up serve as a guide. It’s diffi cult to believe that all these steps can be accomplished by a ma- chine. Fig. 28: Analog version of the try-in. A good fi rst impression was obtained by just fooling around. Fig. 29 and 30: Ondˇrej Adam hard at work. In order to faithfully recreate the translu- cent edge of the lower front teeth in the upper jaw, he completely veneers the upper incisors. The result after the fi rst fi ring cycle is shown in the picture. Fig. 31 to 36: Not to worry, the members of the CAD/CAM group aren’t spending all their time staring at their computer monitors. They’re also having fun and taking care of some steps manually. In the end, it’s not the method that counts, but the result, which has to look as natural as possible. Fig. 37: Mission accomplished: Helmut Berger has incorporated his virtual crea- tion into the picture of the patient in or- der to check the length and alignment of the teeth. Fig. 38: The day has come to an end and the excitement is palpable. Due to the large number of entries, the panel of ex- perts including Christian Smaha (centre), a recognized Viennese dental technician, is consulted to help with the shortlisting process. Fig. 39 to 41: And the winner is … the Slovakian dental technician Martin Ebringer from the conventional fabrication group. The patient im- mediately fell in love with his crowns. They are sparingly layered. Martin Ebringer focused on imitating the surface characteristics and the tooth shape. When he was asked about how he had managed to produce such a fantastic re- sult, he simply said that he had talked with the patient and tried to create what she wanted: in other words, very bright, monochromatic teeth. Consequently, he tried to impart the teeth with a natural appearance by incorporating morpho- logical details.
