Given that the existing product had been identified as hard to understand and use by many of Sybron’s customers; a heightened effort was made to ensure that the new interface would be much more intuitive. Nectar developed the graphical user interface to be an iconic representation of the procedure itself. The “V” is representative of the root canal while the file is visually represented as it travels down to the apex of the root. The depth information is communicated is several redundant layers; first iconically, then reinforced numerically and also with the bolded linear graphic which matches the travel of the file.

During the procedure; the dental surgeon may retract the file – nectar evolved the idea of leaving a graphical “carrot” behind indicating the last position which was a valuable piece of information in improving the process. This was later called out specifically in their patent as one of the unique aspects of the new design.
