Abstract

Introduction: Instrument separation during endodontic treatment decreases treatment success rate up to 19%. Only a limited number of devices are available for the removal of these fractured instruments. The present paper introduces patenting and electromechanical design of a new device consisting of a spring-like instrument for the removal of fractured endodontic instruments from the root canal space.Materials& Methods: This device as been designed in the field of biomedical engineering and consists of mechanical and electrical parts. This article has been adopted from patent #87785 and International Classification A61C; A61K. The device which is the same size as the hand files consists of a spring-like head that can shift from the coaxial mode to the non-coaxial mode. The electric part of this device gives an alarm when a broken file is entangled. The innovative device in fact has a completely different mechanical design and is a combination of a new mechanical design with that of the apex finder.Results: This project consisted of: 1) designing and 2) manufacturing of a prototype. The initial plan and studies began in 2014 in Isfahan Faculty of Dentistry. The patenting procedures began in 2014 and the device was patented in 2015.3D software program was used for designing of the device.Conclusion: There is no similar national or international device available. This registered idea and invention could increase success rates in endodontics by reducing the failure rates if it is mass-produced and used in vitro and in the clinic.
