| Summary: | There are two main causes of endodontic instruments breakage in curved root canals: cyclic and torsion overloading. Detailed analysis of these factors and the evaluation of the root canal anatomy by microCT allowed to formulate the formation principles for instruments which are based on the anatomy of root canal systems. The main aim is to provide the high safety of root canal treatment. These principles, material parameters and physical calculations secured the creation of new type of instrument - super flexible instrument, which is free of disadvantages of existing instruments. The instrument is working always in elastic region of material deformation, so it is secured from cyclic overloading and at the same time disposes improved torsion stability. |
