The University of Mainz determined a precision of 99.6 percent in an unpublished study on digital tooth shade determination using VITA Easyshade. In comparison, the precision for visual shade determination was 72.5 percent. The new VITA Easyshade Generation also offers, in addition to shade determination in seconds, an intuitive touch operating concept as well as interfaces for wireless shade communication. PD Dr. Lehmann reports on his first experiences in this article.
"The innovative design and high-quality workmanship of the new VITA Easyshade V make an immediate positive impression." The smooth surfaces in combination with the practical touch operation are not only visually appealing, but also provide an advantage with regard to hygiene - for example, there are no difficult-to-clean crevices around buttons, according to PD Dr. Lehmann. The color touch display and Bluetooth interface also simplify handling in everyday practice.
The following main recommendations should lead to precise measurement results:
1. Follow the operating instructions exactly,
2. perform multiple measurements, and
3. measure before the start of treatment.
The last recommendation is especially important since teeth can become dehydrated by the suction process, which can lead to shade alteration. This applies both for direct restorations with filling material and for prosthetic restorations.
"In addition to tooth shade measurement, we also make digital photos," reports PD Dr. Lehmann. He has discovered that with the help of photos and the VITA Assist software, information for making prosthetic restorations can be transmitted very comfortably and precisely to the laboratory. The software can also be used well for documentation.
