KKG today supplement IDS 2015 13 March

interview 11IDS 2015 – 13. März 13 March job into the job of a dental technician. Pri- marily,Iamadentistandnotadentaltech- nician but modern dentistry has to face the constantly increasing expectations of patients. Therefore, I was also looking for ways to simplify the process of care and provide a high-quality service — gaining moreandmaybeworkingless,sotospeak. You are also testing KaVo’s Lythos scanner. In your opinion, how does the product differ from other intra-oral scanners currently available on the market? I had a little experience with two other scanners, both with a high perfor- mance and a striking user interface. The Lythos System does not require the use of powders to read the dental elements. Certainly, this is an advantage. But the real difference I noticed was what you did not see: the final result, which I think is what really changes the way of working. The Remote Design Service is another new component in the full prosthetic solution system. Could you please describe the interface? Nowadays, to obtain the best result in the planning process, the dentist and the technician have to get together to agree upon the selection of materials and methods of production. I think KaVo’s designers are the added value that makes the difference. I will continue to work as a dentist! The KaVo Remote Design Service offersplentyofsolutions;it’salwaysthere to listen and to solve problems. Could you please explain a specific workflow in which you used the chairside system together with other new products? KaVo’s CAD/CAM procedures are mainly based on three key moments. First, a data-capturing system, which offers information on the morphology of the dental elements and the scan- abutment involved in the treatment. From this, a three-dimensional digital model is obtained. Second, a powerful software that helps the user plan a specific prosthetic reha- bilitation with the chosen material. Third, a milling machine that, after having received the information processed by the software, performs the prosthetic restoration. I use KaVo’s scanner system almost always now. For me as a dentist, it did not change anything in my workflow. While the procedures on natural teeth are the same, impression taking for implants is simplified considerably. I think that, as clinicians, we cannot lose this chance to obtain a customised abutment. Nowadays, patients’ demands are increasingly related to aesthetical prob- lems and to time savings. The titanium for theabutment,thezirconium,theceramics and new materials such as Enamic, where prevalent ceramic network is reinforced by a polymer network, can be processed with CAD/CAM technology. In a clinic with this technological equipment,weareabletodeliverthepros- thetic tooth with its customised abutment to our patients in only one hour. As a pilot user, how would you describe the learning curve for dental professionals? What does a dentist need to know or prepare for before embracing a fully digital workflow? The learning curve with the first proto- type was frustrating initially, but later on, with the new version, I got a better feeling for the scanner. n KaVo-Technikerin Ester Moll zeigt, wie mithilfe der ARTICA-Software innerhalb von nur zehn Minuten ein Design umgesetzt wird.

Zahn 21 soll mit einer Krone versehen werden. Designvorgaben sind der aktuelle Zustand (Abb. 2), sowie der Spiegelzahn 11. Ein Abdruck der aktuellen Situation wurde gemacht, gescannt und gespei- chert. Der Zahn ist vorbereitet. 14.23 Uhr: Daten sind eingespeichert. 14.26 Uhr: Daten des vorbereiteten 21 und dem Abdruck der Ausgangssituation sind hochgeladen. Die Krone ist im vorbereiteten Stumpf platziert. 14.27 Uhr: Der Schritt-für-Schritt-Assistent zeigt den nächsten Prozessabschnitt an. Die Vorbereitungsschritte werden von der Software über „1-click“ angezeigt. 14.28 Uhr: Die Software zeigt die berechnete Wiederherstellungsform an. Dieser Vorschlag der Software kann immer noch verändert oder angepasst werden. 14.29 Uhr: Mesiale und distale Kontaktpunkte werden festgelegt. 14.30 Uhr: Die Software hat den datenbasierten Zahn positioniert. 14.30 Uhr: Der Schritt-für-Schritt-Assistent bietet an, den datenbasierten Modellzahn (weiß) an die aktuelle Situation zu adaptieren (türkis). Der Prozessabschnitt in der Box (rechts) heißt „Adaptation des Modellzahns“. Die Software berechnet die Abweichungen. 14.30 Uhr: Die Designadaptation ist abgeschlossen. 14.31 Uhr: Dieser Prozessabschnitt erlaubt noch einmal nachträgliche Veränderungen oder Verbesserungen. Weiter geht es mit dem „Continue“-Button. 14.31 Uhr: Das System bietet an, den Antagonisten zu beschneiden (lila). Kontaktpunkte zu den angrenzenden Zähnen können aufgebaut oder eingeschränkt werden. 14.33 Uhr: Das MultiCAD Softwarepaket berechnet jetzt die vordere Zahnkrone, fasst die Daten zusammen und generiert die Fräswerte. Jetzt kann der Fräsbefehl gegeben werden. In die „KaVo Software Suite“ gelangt man über den „CAM“-Button in der DentalDataBase. Darüber wird das Gerät kontrolliert. Über das Start-Menü werden der jeweilige Auftrag und die Werk- zeugpalette ausgewählt und der Befehl ausgeführt. n KaVo technician Esther Moll presents a design made with the ARTICA software package in just 10 minutes. The DentalDataBase user interface shows all individual steps,fromordercreation,scanning,designtodatatransferto the milling machine. To illustrate the rapid and simple realisa- tion of a design, the description of the “step-by-step wizard” contains the time code. Tooth #21 is to be supplied with a crown. Design inputs are the current situation and the mirror tooth No. 11. The impression of the current situation is taken, and the scanned data is stored. The tooth is prepared, and the impression is scanned. 02:23 p.m.Data is stored.  02:26 p.m. Data of the prepared #21 and the impression of the current situation is uploaded. The crown is positioned on the prepared stump. 02:27 p.m.The step-by-step wizard leads to the next step of the process. The preparation line is created by the software via “1-click”. 02:28 p.m.The software shows the calculated restoration shape (stump). This proposal by the software could still be individualised or changed. 02:29 p.m.Mesial and distal contact points are set. 02:30 p.m.The software has positioned the database tooth. 02.30 p.m.The step-by-step wizard offers to adapt the database tooth to the situation. The process step in the box is called “Adaptation of model teeth”. The software calculates the correction. 02:30 p.m.Adaptation of the design is complete. 02:31 p.m.This process step would allow additional changes or corrections. Proceed to the next process step with the “Continue” button. 02.31 p.m.The system offers to trim the antagonist. Contact points to the adjacent teeth can be created or reduced. 02:33 p.m.The MultiCAD software package now calculates the anterior tooth crown, compiles the data and generates the milling data). From here, the order for milling the crown can be issued. Access the “KaVo Software Suite” via the “CAM” button in the DentalDataBase. This controls the engine. Use the start menu to select fabrication job and tool magazine and complete the order. In 10 Minuten vom Design zur fertigen Restauration In 10 minutes, from design to restoration At first, it took me long a time to take a complete impression. Now, I am able to scan a “difficult” mouth in only seven minutes and a “normal” mouth in five minutes. Furthermore, I had to learn how to do a retraction for intra-oral scanning, but this helped me a lot in improving the scanning quality. It’s always necessary to keep in mind that the analogical workflow is not at all easy and free of errors. Taking a tra- ditional impression is one of the most difficult steps in the process of making a precise restoration. Digitalimpressionshavealotofadvan- tages: the improvement of the acceptance by the patients, the chance to preview the preparation in 3-D, the absence of inevi- tabledistortionoftheimpressionmaterial and of the model. I think the pivotal question for dentists is not whether they want to engage in a fully digital workflow, but rather, when they start to do so.
