An endodontic reamer and a method for manufacturing endodontic reamers and
files, more specifically an endodontic reamer having a cylindrical shaft
and a working portion extending forward from a removed end of the shaft.
The working portion includes, typically, a pair of wedged shaped
projecting sections that extend beyond the diameter of the shaft. Forward
from the wedge shaped sections is a nose, typically non-cutting nose,
that has a diameter of about equal to diameter of the shaft. There are
typically two (2) wedge shaped sections projecting outward opposite one
another. Applicant also provides a novel method for manufacturing an
endodontic reamer, which consists of using a two piece mold and placing a
wire blank between the mold, followed by forcing the mold together, under
compression, against the wire blank, to deform the blank into the shape
of the mold parts.
