Definitions
- endodontic instruments such as files and reamers, are used during the root
- the tooth is typically filled with
- high-quality nickel-titanium endodontic instruments can be used.
- the invention also provides a
- the tapered rod is subjected to successive passes of a grinding
- the present -5- invention overcomes this limitation by utilizing multi-pass grinding and
- present invention is that the depth of cut and the feed rate for each grinding
- Figure 1 A is an elevational view of a rod and a grinding wheel
- Figure 4A shows a transverse cross section of the distal end of
- Figure 4B shows a transverse cross section of the proximal
- the rod 10 may be composed of titanium
- Such titanium alloys typically have a titanium
- the alloy consists of 44%
- the preferred speed is 5730 rpm for a six inch wheel. High ⁇
- pass entrance point 60 somewhere between the distal end 24 and the
- microns to a depth of about 100 microns or more, with about 40 microns
- the grinding wheel 1 2 may move at a rapid feed rate, such as 1 800
- This grinding feed rate can vary while the grinding
- wheel 1 2 is removing material along a pass or from pass to pass, but is -1 1 - more preferably held constant while the grinding wheel 1 2 is removing
- the grinding wheel 1 2 can move at a
- the flutes 1 00 also form
