The experiences of the subtractingmethodshaveproventhatzirconiumox- idehasinitiallyonlybeenimplementedwithaveneer covering. More recent versions with a higher trans- lucency are on the other hand used monolithically. When today complete dentures are produced digitally in a working step in the laboratory and the tine-consuming procedure is limited down to two dentist appointment for the patient: why not printed table tops and temporaries soon too? Case studies are already showing now: An implant- supported top jaw complete denture can indeed be made out of PEEK (polyether ether ketone) using the 3-D printing technique and plastic veneers lend it an attractive appearance. PEKK (polyether ether ketone)couldalsobecomeoneofthebasematerials ofthefuture,especiallysinceincombinationwitha veneer composite it displays similar characteristics to veneered zirconium oxide. Digital workflows make 3-D printing additionally attractive In addition to new materials, the possibility of inte- gration in the digital worlds also provides a boost. For example, the 3-D printing of dental technology models could develop into a frequently used option as a result of the further distribution of intraoral scanners. “3-D printing offers extraordinary potential,” said Dr Martin Rickert, Chairman of the Association of the German Dental Manufacturers e.V. (VDDI) convinced. “This also applies to the closer col- laboration between the dentists and the dental technologists, which will be promoted through the joint work in the digital workflows. The backward planning in implantology is an example of this, where 3-D printing creates a concrete additional option in theform of the production of detailed drilling templates at the laboratory. At the Inter- national Dental Show in Cologne, the opportuni- ties of this modern production technology can be experienced close-up with tangible innovations and in direct contact to the respective manu- facturers.” The International Dental Show takes place in Co- logne every two years and is organised by the GFDI Gesellschaft zur Förderung der Dental-Industrie mbH, the commercial enterprise of the Association ofGermanDentalManufacturers(VDDI).Itisstaged by the Koelnmesse GmbH, Cologne.
