Unanimous conclusion of ceramic professionals: unobtrusively beautiful – a true Creation!

Experts’ round table on the new zirconia ceramic Creation ZI-CT with Willi Geller in Zurich

Years of experience, constant developments and continuous exchange of information with users: tradition, innovation and communication have been part of the concept of Creation Willi Geller for 25 years – for even better, safer and more aesthetic products in dental technology. Thus the suggestions from the front line to the branded ceramic supplier provide valuable pointers to material and system improvements. Twenty European dental technicians and oral designers recently met with Willi Geller in Zurich in order to exchange information about the latest innovation, the leucite crystal zirconia ceramic Creation ZI-CT, which is being launched at IDS 2013. Of course, they also had lively discussions about their own professional sphere and about trends in dental technology.

To find out how the new feldspar ceramic performed in the first laboratory trial, Willi Geller had invited all participants in the beta-phase to Zurich for an exchange of opinions and experiences. In his laboratory, the aesthetic and material science aspects of Creation ZI-CT were discussed and commented on for a whole day. In his assessment, dental technician Andreas Nolte put what everyone was saying in a nutshell: “The new zirconia ceramic is unobtrusively beautiful and hence a true Creation.“


High-fusing, high aesthetics and high stability

After seven months and up to 800 fabricated units per participant, the beta-phase for the new ceramic system from Creation is completed. The verdict of the ceramic pros was unanimous: high-fusing, high aesthetics and high stability! Willi Geller was excited about the “natural play of light”, Joachim Maier ZTM found Creation ZI-CT set a “new benchmark among zirconia ceramics”, Ulrich Werder ZTM praised “the clear colours and the consistent brilliance” and from the viewpoint of Peter Biekert ZTM it was a “sensational ceramic which is perfectly coordinated in all areas”.

As well as the impressive aesthetics, for which the high feldspar content is partly responsible, the opinion leaders also praised the material science properties of the new leucite crystal veneering ceramic. For instance, it was felt that the micro-fine crystalline structure would greatly improve the mechanical strength and thereby provide a durable ceramic structure.

Furthermore, thanks to the extremely low shrinkage, which the dental technicians compared with the proven metal-ceramic Creation CC, fewer correction firings would have to be done. Peter Biekert: “And physically Creation ZI-CT is dynamite!“Due to the basically low thermal conductivity of zirconium dioxide, it is important to watch for any slow heating of the framework material. According to Patrick Boche ZTM, Technical Manager at Creation: “Zirconium is a poor heat conductor, which is often forgotten in everyday laboratory practice.” To prevent stress changes and flaking, when setting the pre-drying time, heating rate and linear long-term cooling, the volume of the work must always be taken into account and the individual parameters adapted to the particular situation in line with the material being used.


Willi Geller: “The laboratory’s future lies in aesthetics!”

After a thorough exchange of experiences regarding Creation ZI-CT and evaluation of the field study, the ceramic specialists talked about the latest trends in dental technology, also discussing the fast-paced development of CAD/CAM technology and the monolithic materials. As well as all the dental technology achievements, it was felt that the nature of teeth and their uniqueness should still remain paramount. That presupposes a high degree of experience but also a passion for the profession. According to Joachim Maier ZTM: “But afterwards you get back the visibly satisfied smile of your patient!”.

Many participants in the experts’ round table in Zurich found there was a negative trend in the area of dental technology education and a considerable need for training. Young technicians ought to be taught the trade more rigorously again – starting with knowledge about firing (furnace parameters and assessment of firing results) and lifelike layering of ceramic materials. Willi Geller’s conclusion: “As seasoned ceramists we should pass on our own experience and our knowledge to the younger generation. Then they can copy and add to that knowledge base intuitively and integrate it into their own personality. The scope for differentiation and hence our future lies in the aesthetics and quality of our work. In this respect, the new Creation ZI-CT is an absolute asset, after all it was developed by dental technicians for dental technicians – by ourselves for ourselves!”
