Claims22
A highly flexible dental instrument for endodontic applications having a free end insertable into a root canal of a tooth, comprising:
- an elongated tapered instrument body having a proximal end and a reduced diameter distal end and formed of a plurality of elongated flexible metallic strands extending from adjacent said proximal end to adjacent said distal end, at least one strand having at least one scraping edge.
A highly flexible endodontic instrument having a free end insertable into a root canal of a tooth comprising;
- an elongated tapered body made up of at least one center strand and at least one outer strand wound spirally around the center strand, at least one outer strand having at least one scraping edge thereon.
A highly flexible endodontic instrument having a free end insertable into a root canal of a tooth comprising;
- an elongated body made up of a plurality of flexible metallic strands, at least some of which are twisted with respect to others and at least one of which has a non-circular cross-sectional configuration providing at least one spiral scraping edge.
A highly flexible instrument for endodontic applications comprising;
- an elongated instrument body formed of a plurality of elongated flexible metallic strands including at least one central strand that is tapered in cross-section from a larger dimension adjacent said body proximal end to a smaller dimension adjacent said body distal end, said at least one central strand being surrounded by at least one spirally wound strand having at least a portion that is non-circular in cross-section.
