Latest Patents

Otsen's latest patents include a method of manufacturing superelastic endodontic files and the files made therefrom. This method involves grinding a superelastic wire to create a file blank, while rotating one end of the blank and preventing the rotation of the other end. The file blank is kept in the austenite phase until it is twisted to form a stress-induced martensite, which is then plastically deformed by the twisting process. Additionally, a heat treatment step can be performed at various stages of the process. This innovative method allows for greater flexibility in the design of endodontic files, including the production of a rhomboid superelastic file. Another patent focuses on the superelastic endodontic instrument itself, detailing similar manufacturing processes and the potential for heating the blank through electrical methods or heated liquids.
