Definitions
- Instrument for mechanical reaming of root canals and sequence of instruments comprising at least one such instrument.
- the present invention relates to the field of endodontic instruments for boring dental canals, and more particularly to a specific instrument for boring dental canals.
- the invention also relates to a sequence of instruments comprising at least one specific instrument of this type.
- the endodontic treatment consists, first of all, in a mechanical bore of the root canal then in its obturation, final aim sought.
- the obturation is achieved by adding an external material, for example gutta-percha.
- the gutta-percha is introduced into the channel prepared for this purpose in the form of heated cones, which has the consequence of softening the gutta-percha and therefore making it malleable, which are condensed by mechanical action at using glanders to ensure either a so-called “vertical” condensation or a so-called “lateral” condensation, relative to the longitudinal axis of the reamed root canal.
- the gutta-percha can also be placed in the canal by implementing the devices described in documents US-5,588,835 or Q 93/14714.
- the main object of the present invention is to provide a specific instrument for the preparation of the root canal at the apical level which makes it possible to solve the aforementioned problems.
- the invention also relates to a sequence of endodontic instruments for reaming the root canals comprising at least one specific instrument according to the invention.
- the invention relates to an instrument for reaming the root canals, in particular in the apical zone receiving at its proximal part a handle allowing its manual use or on the head of a dentistry contra-angle, the distal part of said blade being a tip of a type known per se, characterized in that the active cutting part of the blade has, from the tip and in continuity, two conical sections such that, in addition to the tip, each conical section has a stronger taper than the least distal part which is immediately adjacent to it.
- the invention also relates to a sequence of endodontic instruments for the progressive boring of the root canals, characterized in that it comprises at least one instrument of the above type.
- the invention will be better understood using the description given below of an operating mode implementing a sequence of instruments in accordance with the invention, with reference to the appended schematic diagrams, referenced from 1 to 7, which illustrate the progressive boring of a root canal to arrive at the desired canal profile with apical base.
- the following sequence of instruments is used, for example:
- n ° 1 has an apical diameter of 0.20 mm and a taper of 6%.
- - instrument No. 2 has an apical diameter of 0.20 mm and a taper of 4%.
- - instrument No. 3 has an apical diameter of 0.20 mm and a taper of 2%.
- n ° 4 is identical to n ° 2
- n ° 6 has an apical diameter of 0.20 mm and a taper of 8% over 4 mm then 3% over the rest of the active length
- No. 7 has an apical diameter of 0.20 mm and a taper of 10% over 4 mm then 2% over the rest of the active length.
- instrument No. 1 which gives the channel the reference profile (1) in Figure 1.
- the instrument is engaged in the channel up to approximately 7 mm from the apex. We see that this first action determines the maximum bore diameter with, as a corollary, the minimum depth.
- Instrument 3 is the first to be engaged up to the apical level.
- Instruments No. 5, No. 6 and No. 7 are then engaged sequentially each to the apical level.
- the material is gradually extracted according to the hatched areas in Figures 3, 4 and 5 to arrive at the profile of the desired channel with apical seat (8).
- At least two instruments of a series of instruments have a conical part of the same conicity.
- each conical section of each instrument has an identical conicity for all the instruments of the same sequence.
- At least one instrument has a conicity different from that of the other instruments of the sequence in their equivalent part.
