Reciprocating files are especially useful as they allow particularly fast treatment. However, they can also have a severe strain on teeth by causing very fine fissures – so-called microcracks. This drawback is now a thing of the past with DentaPort ZX Set. The modular system is fitted with the Optimum Torque Reverse function (OTR) – and makes it particularly easy for you to protect teeth in the best possible way. The EndoWave OTR files were developed to optimally support the OTR function
In the root canal, the file is always subject to mechanical influences that act against the drive torque of the endomotor. These can lead to torsion and, consequently, result in a file breaking. In order to protect both file and teeth, it is therefore vital to restrict the torque acting on the file. With the OTR function, the file changes its rotational direction as soon as a specific torque level has been reached. After a reverse turn of just 90° it reverts back to the cutting direction. The advantage: this procedure is only repeated after a further turn of 180° if the file is under any strain. If there is no strain on the file, it continues cutting.
