Piezoceramics shorten root canal treatments
When carrying out root canal treatment procedures, dentists need to insert a file deep into the root canal to remove the inflamed tissue. The rotating file often gets jammed and must be cleaned regularly. Researchers at the Fraunhofer Institute for Ceramic Technologies and Systems IKTS have developed a piezoceramic stack actuator that overlays the rotating motion with a vibrating motion. The file does not get jammed as often, meaning that procedures on patients can be completed faster. This technology is also useful for other medical applications, for example in diagnostics and cancer treatmen...
