Title:
ENDODONTIC INSTRUMENT
Document Type and Number:
WIPO Patent Application WO2007053746
Kind Code:
A9
Abstract:
A method of manufacturing endodontic instruments is disclosed. Each of the instruments includes a substantially non-cutting pilot portion, a relatively short working portion, and a flexible shank portion which is of a substantially smaller average circumferential span than the working portion. The working portion of one instrument may have a maximum circumferential span as that of the blank from which it is made. The instrument may be treated with either a surface treatment and/or a bulk treatment. The instrument may have a handle at its distal end for manual manipulation, or may be adapted for attachment to a mechanical handpiece. The non-cutting pilot, the short length of the working portion, and the flexibility of the shank combine to allow the instrument to be used in curved root canals without causing undue change in the natural root canal contours.
