The unique CEREC system enables dentists to prepare, design, and produce final restorations such as crowns in just one session. Patients are not only spared a temporary and a second appointment, but also the unpleasant tray impression. Ergosign's task for the UI redesign was to make this process for dentists even more natural: Trackball and keyboard were to give way to intuitive touchscreen operation. The graphical user interface should not only be modern, but also fit seamlessly into Dentsply Sirona's new corporate design.
Due to the new development of the hardware, there were numerous factors that had to be considered during the project. Our project team planned the testing of the hardware prototypes at various stages of development with Dentsply Sirona in order to optimally harmonize the hardware with a redesign and to gain valid insights into the operation of the software. Due to the change in operation from intensive use of a keyboard and trackball to a touch screen, the project also included conceptual changes and improvements. To gather enough feedback, the Ergosign design team works in weekly design sprints in close coordination with Dentsply Sirona - requirements are estimated and prioritized together with regard to their implementation and effort.
Since the beginning of the project, end users such as dentists and technical experts have been an integral part of the project: their feedback was collected at the earliest stage of the project - when testing the hardware. In addition, project participants with expert knowledge, e. g. in the field of dental technology, were also on board. Their expertise was a valuable asset in finding metaphors; the entire interface benefited from their in-depth know-how. The agile project approach was lined up with a long-term release plan.Once a quarter an on-site Jour Fixe took place with all project participants (design, development, customer) to discuss the current status. This also enabled the project partners to coordinate their activities in person.
However, digitization added work steps that were not available at the time of conventional impressions. Thanks to CEREC's powerful artificial intelligence, many of these steps are automated and shorten the workflow significantly. Like CEREC, the interface design is unique. It combines photo realistic 3D renderings of jaws and teeth with a user-friendly interface and a clear, simplified navigation structure.
We streamlined both the overall design and the effects and animations to support both a clear design language and focus on the most important: the relevant content on the work surface and the 3D models of the teeth and jaws. Thus, the new UI contributes to increasing the efficiency of work for end users. The time savings also make the treatment more pleasant for the patient and both sides - user and patient - benefit equally from the design. The scalable, cross-project design has been optimized for touch operation, which is another factor for improved operation.
