IDS is showing all facets of outstanding concepts and materials – established for decades – pioneering thanks to continual further development
Announcements of disruptive technologies continue to dominate the headlines. However, at the same time there are stable constants - trusted materials and methods over decades, which still impress us and show the way forward. We are highlighting four examples of such below that are representative of many others: a colour measurement system, an alloy and an occlusion tester.
For 90 years: A colour measuring ring has been the standard In order to allow prosthetic restorations to look natural or make them "invisible" in an existing row of natural teeth, the first and elementary step is determining the colour of the teeth. To this end, 90 years ago the Dr. Hiltebrand Zahnfabrik that had just been renamed Vita Zahnfabrik developed a colour scale with 24 sample colours.
The preceding VITA classical A1-D4 colour-measuring ring has established itself as the standard in the fields of dentistry and dental technology ever since. Today, it comprises of 16 natural tooth colours and three bleached colours. The success is based on its reliability over decades and also on innovative enhancements. Above all, in the form of the classic colour-measuring ring with the VITA SYSTEM 3D-MASTER one has provided a further option. With 26 natural tooth colours and three tooth bleaching colours it has enabled both a differentiated and systematic approach in three steps for the past 22 years. In a modern form of execution, intermediate colours can even be achieved to fulfil the highest aesthetic demands.
A further success factor lies in the product-related and didactically elaborate concepts for users. For instance, since 2008 the company has been offering a special system called the VITA Linearguide 3D-MASTER to facilitate the transition between conventional colour-measuring systems and a precise shade determination and shade communication using the VITA SYSTEM 3D-MASTER.
For over 85 years: Remanium For decades non-precious alloys have also been providing new answers to basic dentistry and dental technology questions over and over again. It may amaze some people, but the problems one faced one hundred years ago were very similar to those of today: High prices for gold and platinum, a frantic search for alternatives, which of course had and have to be suitable for implementation in the mouth - both physically as well as physiologically.
One of these most early non-precious metal alloys was called Remanit at the time, meanwhile it is known as Remanium. A very high biocompatibility, flexible in processing and very favourably-priced - boasting these characteristics, the success was pre-programmed. An important step in the further development was the possibility of ceramic veneering.
The cobalt/chrome-based material has also been available in ceramic alloy versions since the end of the 1960/start of the 70s. An additional material option brought further modifications at the beginning of the 1980s, which was able to be implemented for both metal crowns and bridges as well as for veneered frameworks. In the course of the present century, the assortment was enhanced by a laser weldable titanium and carbon-free model casting alloy and by further options: one with a very low hardness, another with a particularly high processing reliability and yet another that can be veneered with the same ceramics as for bio alloys with a high content of gold.
At present, Remanium is making the trend shift from casting to milling materials and to an even greater extent to metal powder for the laser melting method ("selective laser melting, SLM). Whereby casting remains interesting, especially in combination with semi-digital model casting processes in accordance with the CAD/Vest method: Digital work preparation via a model or mouth scan, digital design, 3D printing or milling in wax or plastic, followed by casting and elaboration as usual. However, the demand is shifting more and more away from the well-known casting cylinders for the dental technological precision casting, to milling blanks for machining and micro-powdering in the scope of the SLM method. The latter demands that the manufacturer strictly observes certain qualities regarding the particle size and particle size distribution. This ultimately creates the necessary prerequisites for the dental technician for a high level of precision and reduces the material consumption. Because the laser melting method works practically without any waste.
Off into the digital era with a classic: BK articulating paper Dr. Hans Mathias Bausch combined the abilities of a dentist and a great interest in chemistry in one person and in the year 1953 he developed the product "BK 01 articulating paper 20 microns" - at last paper that draws accurately even in a moist environment. Together with his father, the dentist, Dr. Jean Bausch, he founded Dr. Jean Bausch KG. The cornerstone for modern occlusion materials had been laid and in the period that followed the task at hand was to answer fundamental questions with suitable innovations: How does pressure-sensitive articulating paper have to be designed so that it can illustrate different chewing strengths in different shades? How can a good staining be achieved on metal and ceramic surfaces and on moist occlusal surfaces? How can one prevent the static charging of an occlusal film?
One found convincing answers to these and many other questions. One approach consisted of wafer-thin films with great hydrophilicity, coated with a novel colour mixture, allowing the colour to have a better effect on smooth surfaces.
Occlusal testing has also moved forward into the digital era, a system has namely been developed that unites the traditional and digital representation of the pressure ratios. Here a handheld device is used in combination with a 60-micrometre thin, one-time pressure sensor with a red colour coating. This enables the traditional colouring on the occlusal surfaces of the patient. At the same time, the data of the occlusal pressure ratios is transmitted to an iPad and illustrated as a 3D diagram including the chewing strength distribution via an app.
Known quantities and small niche products - both make IDS attractive "The current top innovations belong to every IDS, but for me personally reliable constants, the evergreens over decades are equally important," stated Mark Stephen Pace, Chairman of the Association of the German Dental Industry e.V. (VDDI), enthusiastically. "In all sections, I sense the innovative power of the exhibitors at the International Dental Show and of course well-established products react to current trends, indeed they often help them advance into market leaders. Incidentally, apart from known products and big names these also include many niche products. Because at the first glance it is often small assistants that prove to be of great and indispensable use for the daily routine in the practice and laboratory. For this reason alone, I personally find it absolutely worthwhile visiting IDS."
About IDS IDS (International Dental Show) takes place in Cologne every two years and is organised by the GFDI Gesellschaft zur Förderung der Dental-Industrie mbH, the commercial enterprise of the Association of German Dental Manufacturers (VDDI) and is staged by Koelnmesse GmbH, Cologne.
