Definitions
- the present invention relates to an endodontic instrument, in particular an instrument for boring a root canal of a tooth of a patient, said instrument having a longitudinal axis and comprising a working zone arranged to form and / or shape and / or or cutting and / or cleaning the wall of the root canal of the tooth, this working area being provided with a holding tip arranged to be fixed on a support.
- the cleaning and shaping of the root canals of a tooth for receiving the filling substances is carried out by the use of boring instruments having an active part, called a working part, which has the purpose of to shape and clean the root canal to prepare it for receiving treatment and sealing materials.
- the root canals often have particular geometries with complex curvatures and reduced sections, such as constrictions or oval areas, which are not well suited to the introduction of preparation and shaping instruments. This is why instruments called limes must have sometimes contradictory characteristics: These files must be thin but resistant while being flexible enough to follow the curvatures of the root canal and reach its end while remaining hard enough to cut and cut the walls of the root canal. this channel.
- the US publication US 2010/0233648 discloses an endodontic instrument which is made of a superelastic material which has a first shape at the time of its introduction into the root canal and which takes a second shape when it is inside this channel.
- This shape modification 5 is related to the property of superelasticity of the material, which allows the instrument to undergo deformations due to mechanical constraints imposed by the profile of the channel.
- the present invention proposes to overcome all of the above disadvantages and to provide means for ensuring effective preparation of the root canal, by providing the practitioner with an adaptable instrument that is easily introduced to the patient. interior of the root canal and which may nevertheless have a suitable shape to ensure the preparation for the root treatment and the closure of this channel.

- said second predetermined variation of the temperature of this instrument is a lowering of the temperature.
- Said lowering of temperature, to a value called transformation temperature which advantageously causes the passage of the austenitic phase to the martensitic phase, is in a range of temperatures between 60 ° and 0 ° C and preferably between 40 ° and 40 ° C. 25 ° C.
- said at least one working zone may be made of a metal alloy having shape memory properties enabling it to take a retracted form at room temperature and a structured form expanded to a higher temperature at the time of or after its introduction into said root canal.
- said metal alloy having shape memory properties is an alloy chosen from the following alloys: nickel-titanium, copper-zinc-aluminum-nickel, copper-aluminum-nickel, or zinc-copper-gold -fer or a combination of at least two of these alloys.
- said expanded structured form may have a twisted appearance, a substantially flat twist shape or a twisted twisted form of substantially circular section.
