36 I I industry report _ Tizian CAD/CAM symmetry and composition. In this case, which would have been a challenge for every CAD/CAM system on the market, the Tizian Creative RT design software demonstrated significant advantages during the shape-forming process, especially for the attachments and the distal implants. We were able to call the antagonists every time we needed to during the entire modelling process. The software automatically arranged the occlusal and approximal contacts but these can also be adaptedmanuallyifnecessary.Aftertheconstruc- tion had been adapted to the bite, we proceeded to shrink the crowns and pontics. With the entire paletteofformingtoolsavailableforreshaping,we reduced as much as we needed to. The connectors were set quickly and easily, while one was able to choose between different shapes, move in all di- rections,andchangeheight,weightandthickness. Figures 9 to 15 show the final construction before and after being seated in the patient’s mouth. _Case II (Figs. 16–24) This 40-year-old female patient was not sa- tisfied with the look of her smile. By restoring her teeth, we were able to change the way the patient felt about her appearance. We selected a 12-unit zirconiumframeworkwithceramiccover,ahighly aesthetic solution. _Case III (Figs. 25–27) For this 54-year-old female patient, we creat- ed two temporary constructions from advanced PMMA composite materials for teeth #15 to 25 and #35 to 45. The two bridges, which she was required to wear for three months, were then replaced by zirconium constructions. The two bridges were placed on implants. The modelling processfollowedwasthesameasdescribedinthe previous cases. _Conclusion The Tizian CAD/CAM system enables rapid manufacture of highly accurate restorations, both permanent and temporary. With user-friendly software and a large variety of software tools, as well as a fast and easy scanning, modelling and millingprocess,thematerialsareprocessedquickly and accurately with results hardly distinguishable from natural teeth. This exceptional piece of tech- nical equipment proved to provide reliable and consistent results and product quality, as well as excellent bio-compatibility of the materials. Additionally, compared to cast-metal techniques, considerably less time was needed, while accuracy of fit and precision increased._ CAD/CAM 2_2010 Art Dental Hristo Botev 40 7000 Russe Bulgaria artdental.bg@abv.bg CAD/CAM_contact Fig. 22 Fig. 23 Fig. 24 Fig. 25 Fig. 26 Fig. 27
