The DentaPort OTR Rotary is an advanced endodontic handpiece designed to enhance root canal preparation by integrating both rotary and reciprocating motions. This device utilizes Morita's Optimum Torque Reverse (OTR) technology, which combines the efficiency of continuous rotation with the safety of reciprocation. The OTR function allows the file to rotate continuously in the cutting direction until a preset torque limit is reached; at that point, the file reverses by 90° to release stress, then resumes forward rotation. This mechanism reduces file fatigue and the risk of breakage, ensuring safer and more efficient canal shaping.
Please note that the DentaPort OTR Rotary does not include the apex locator module. For comprehensive functionality, it is recommended to use this handpiece in conjunction with the DentaPort Root ZX apex locator, which allows for simultaneous canal measurement and preparation, thereby improving treatment efficiency and accuracy.
