It is the most sophisticated root canal filling endodontic instrument available in the world today. The Elements Obturation Unit with System B produces results which are efficient, predictable, and accurate. It has replaced traditional method of using Plant based Cones (GP cones) to fill the canals. This system uses prefilled cartridges of flowable GP that is extruded into the root canal at very high temperature. The root canal fill thus achieved is accurate, complete in all 3 dimensions and all the potential root spaces inside the tooth are filled, greatly minimizing the risk of future infection and consequent RCT failure.
