ENDO PILE FOR DENTAL ENDODONTIC TREATMENT

摘要

The present invention provides an endo file for dental endodontic treatment, the endo file including: a head portion inserted into and detachably coupled to a hand piece; a tissue removing portion inserted, from the lower side of the head piece, into a patient's root canal for removing the nerve of a tooth; and a stress dispersion portion provided between the head portion and the tissue removing portion and having at least one horizontal penetration hole so as to buffer stress concentration generated during the rotation of the endo file, and to minimize endo file breakage.
