摘要

The invention concerns a blank for making an endodontic instrument using a grinding technique, characterized in that it comprises a cylindrical portion (1) and a generally conical portion (2) designed to be machined, said machined portion forming the active part (3) of the final endodontic instrument. The generally conical portion (2) constituting the housing (8) of the final shape provided to the endodontic instrument after machining. The invention also concerns the method for making an endodontic instrument provided with at least one lip with helical cross-section using the inventive blank.
