A wide range of splints, models, drilling templates, indi- rect bonding trays, in the near future temporary and permanent dentures—almost everything can be printed. Laboratory systems now offer even bigger building platforms and convenient remote maintenance for network-compatible models. Meanwhile, the speed is picking up—just to get an idea of the magnitude: seven splints in one hour are definitely possible today. Innovative software even enables a combined ad- ditive/subtractive production: where it comes down to the highest precision, the machine subsequently carries out an automatic milling process and thus cre- ates overall a consistently high surface finish. Today, multi-material printers are perhaps visible on the ho- rizon. For example, six plastics are mixed to make a new compound with the defined required properties; for instance, with specific colouring or interior colour gradients for a patient-specific design. As an alternative to their own production, the labora- tory can also outsource jobs to a central or industrial sup- plier. Models can be delivered within short lead times, prompt service is offered using digital technology. Target figure = primary stability If a tooth is no longer worth preserving despite to- day's endodontic and tooth preserving possibilities, im- plantology treatment is more and more frequently an option, which is now becoming even more interesting: new instruments with sharp working tips and a thin profile enable a tissue-saving extraction and thus of- ten make elaborate bone augmentations superfluous. Fibre-reinforced composites are used as super- structure material to provide a “shock absorber” effect, which offers a plus in durability and biting feeling. Corresponding CAD/CAM blocks can be processed chairside in the meantime even without separate firing processes. When fixing implant prosthetic constructions us- ing locators (often an alternative to full dentures) a high pivoting capacity now allows divergences of up to 40 degrees between two implants. And thanks to a special holding mechanism, the dentures can be extracted particularly easily using a hydraulic release system during the recall appointment. If a conventional mucosa-supported full denture is chosen, cold curing resin with many of the material characteristics of heat curing polymer offer the dentist totally new possibilities. Such pink denture plastics are high impact, lie nicely on the gums of the patient and can nevertheless still be comfortably processed in the laboratory. Step towards the practice and laboratory of tomorrow New super-sharp scalers, new tiny mini implants, new ceramics for press technology processing, new embedding materials—this list is ongoing. The industry heads the ranks in many areas with both analogous and digital innovations. During their tour around IDS in Cologne the dentists and dental tech- nicians took advantage of this to collect ideas for their practice and laboratory of tomorrow, based on well-founded knowledge thanks to the compre- hensive offer of the exhibitors._ New implant systems are appearing that consider- ably increase the primary stability through compre- hensive further developments. Certain engines now dispose of a non-invasive stability measurement so that the optimal service life of an implant can accu- rately be determined. Editorial note: 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.
