Current developments in aesthetic dental medicine and technology – New CAD/CAM-supported fabrication options – Digital workflow creates new opportunities for laboratories – a main topic at the IDS (International Dental Show) from March 22 to 26 in Cologne
Digital high-tech methods are becoming ever more widely used in the procedures of aesthetic dentistry, both in dentist’s practices and dental laboratories. This applies especially to the precise forming of ceramic or metallic foundations for crowns and bridges, as well as to implant prostheses and associated ceramic or plastic veneers. “This subspecialty has in recent years continued to gain in importance, since ever more patients ask their dentist how their teeth can be restored to both functional and aesthetic perfection,” explains Dr. Martin Rickert, Managing Board Chairman of the VDDI (Verband der Deutschen Dental- Industrie / Association of German Dental Manufacturers). To meet this strong demand for the latest in high-tech dental care more efficiently, users can now resort not only to conventional but also to digital methods, making CAD/CAM-supported ceramic veneer technique possible for the first time.
Digital technologies have been the focus of research and development in dental science and industry for years, and now they are increasingly shaping the daily working routines in dentists’ practices and dental laboratories. Aesthetic dentistry has made significant advances thanks to electronic colorimetric systems and digital metho100 ds for making intraoral moulds. In particular, the diverse methods of CAD/CAM-supported design in dental restorations – especially with the use of zirconium high-strength ceramics – and layered or pressed ceramic veneers are now providing excellent solutions for aesthetically and functionally superb dental prosthetics. Dentists, dental technologists and dental practice employees can now look forward to the International Dental Show (IDS) from 22nd to 26th March in Cologne as the very best source for information about the current status of aesthetic dentistry and for the opportunity of discussing issues with knowledgeable manufacturers’ representatives.
Among the latest versions of digital workflow are all-ceramics monoblock processes using CAD/CAM methods to make anatomically complete restorations from lithium disilicate or zirconium dioxide ceramics. And the dental industry supplies modern CAD/CAM veneer systems in which the restoration is first created virtually with all anatomical details and then subdivided into two partial data records. One of these datasets represents the foundation and is used for its fabrication from zirconium dioxide; the other dataset is used to mill the pre-sintered veneer ceramic. Then the milled veneer is attached on top of the foundation, coloured and sintered. Similar methods can also be used with lithium disilicate ceramics. At the IDS 2011, dentists and dental technologists have the opportunity of being introduced to the latest digital concepts in aesthetic dentistry by manufacturers’ specialists.
In addition to a comprehensive presentation of high-tech in dentistry, this unique globally leading trade fair also provides a thorough overview of proven traditional technologies. Conventional treatments using ceramics, precious metals or NEM alloys in their veneers – either processed in layer or in laminated forms – continue to be very useful in dental prosthetics. At the same time, plastics technology has also made progress in developing aesthetically pleasing plastic veneers: Innovative composite materials provide unprecedented abrasion resistance as well as the required colour fidelity for the creation of high-quality structural designs.
“Professional visitors from dentist’s practices and dental laboratories can look forward to the International Dental Show, the world’s largest trade fair for dental medicine and dental technology in Cologne from 22nd to 26th March 2011 as an excellent opportunity for gathering information from the exhibiting companies’ specialists, other experts and experienced users about the whole spectrum of aesthetic dentistry and especially the latest CAD/CAM methods for making perfect ceramic veneers and substructures,” asserts Dr. Markus Heibach, CEO of the VDDI. IDS takes place in Cologne every two years and is organized by the GFDI Gesellschaft zur Förderung der Dental-Industrie mbH, the commercial enterprise of the Association of German Dental Manufacturers (VDDI) and staged by Koelnmesse GmbH, Cologne.
