Definitions

• the present invention relates to the field of processes for filling the teeth with a canal, and more particularly to the phase of filling, properly speaking, the canal of the tooth using a filling product of the gutta percha or other type.
• a paste which is introduced into the dental canal using a canal instrument called a “condenser” comprising a propeller and placed on a handpiece.
• the present invention also relates to a device for providing sealing product as well as to a container for sealing product.
• the prior art already knows methods of canal obturation.
• the prior art knows, for example, the method which consists in using instruments whose body is made of plastic and on which gutta percha is attached. To achieve the obturation, the assembly is introduced, after heating, into the channel, but the major drawback of this method is that the plastic body remains in the channel and considerably interferes if subsequently it is necessary to take up the shutter work performed.
• the prior art also knows the method which consists in placing the obturation product on an instrument called a “condenser” in the form of a canal instrument provided with a propeller oriented for example to the left and placed on a part to hand, in order to allow to deposit, or “condense” the obturation product in the channel by reverse rotation of the pitch of the propeller of the instrument.
• a condenser in the form of a canal instrument provided with a propeller oriented for example to the left and placed on a part to hand, in order to allow to deposit, or “condense” the obturation product in the channel by reverse rotation of the pitch of the propeller of the instrument.
• obturation product such as gutta percha for example
• the gutta percha is placed in a syringe placed in a heater and the plunger of the syringe is actuated, when the gutta percha is ready, so to deposit it on the canal instrument positioned just at the exit of
• This method has a double disadvantage, on the one hand it does not allow to precisely control the amount of gutta percha applied to the canal instrument and on the other hand, the amount of gutta percha contained in the syringe being important, the temptation is great, for the practitioner to treat multiple dental canals belonging to different patients with the same syringe. In the latter case, the practitioner then risks contaminating the second patient (s) with bacteria coming from the first patient (s).
• the present invention intends to remedy the drawbacks of the prior art by proposing to present the filling product in the form of at least one dose placed in a cartridge-type container, each dose being individual and corresponding substantially to the quantity necessary for the treatment and obturation of a single canal, the canal instrument being immersed in rotation or stopped, in one of said cartridges comprising a dose of obturation product, which makes it possible to collect on the walls of the canal instrument the quantity of obturation product just necessary for the operation of obturation of the dental canal.
• the method according to the invention therefore makes it possible to carry out the filling phase strictly speaking of the tooth canal using the just necessary quantity of filling product and under optimum hygienic conditions.
• the device for providing sealing product according to the invention is remarkable in that it comprises means making it possible to bring and maintain at the desired temperature at least one cartridge containing sealing product in the form of a dose corresponding substantially to the amount necessary for the treatment and obturation of a single channel.
• the cartridge-type filling product container intended to allow canal filling according to the invention is remarkable in that it comprises at least one dose of filling product corresponding substantially to the quantity necessary for the treatment and single channel shutter. It can therefore be sold independently or in large quantities, ready to use and disposable after use.

• the process according to the invention is a process for obturating the canal using a obturation product (1) of the gutta percha or other type, in the form of a paste, which is introduced into a dental canal using a canal instrument (2) called a “condenser” comprising a propeller and placed on a part hand (3).
• the method is characterized in that said sealing product (1) is in the form of a plurality of doses (4) each arranged in a cartridge (5), each dose (4) corresponding substantially to the quantity necessary for single channel treatment and obturation.
• the root canal instrument (2) is immersed, in rotation or stopped, in one of said cartridges (5) comprising a dose ( 4) of filling product (1) in order to collect on its walls the quantity of filling product just necessary for the filling operation, as illustrated in FIG. 2.
• a dose ( 4) of filling product (1) in order to collect on its walls the quantity of filling product just necessary for the filling operation, as illustrated in FIG. 2.
• the present invention also relates to a device (6), illustrated in FIG. 1, for providing filling material (1) of the gutta percha or other type, in the form of a paste, which is introduced into a dental canal using a canal instrument (2) called a “condenser” comprising a propeller and disposed on a handpiece (3), characterized in that it comprises means making it possible to carry and maintain at the desired temperature at least one cartridge (5) containing obturation product (1) in the form of a dose (4) corresponding substantially to the quantity necessary for the treatment and obturation of a single channel.
• the device (6) can, for example, be in the form of a housing (7) comprising a plurality of recesses (8) in each of which can be positioned a cartridge (5).
• the means making it possible to bring and maintain at least one cartridge (5) at the desired temperature can consist, for example, in that the said recess (s) (8) are arranged in a heating body (9) heat conductor heated to using an electrical resistance.
• the device (6) can also include a switch button (10) and an operation indicator (11).
• the present invention also relates to a cartridge (5), illustrated in FIG. 3, intended to allow a canal obturation using a obturation product (1), characterized in that it comprises a dose (4) individual filling product (1) corresponding substantially to the quantity necessary for the treatment and filling of a single channel.
• Said cartridge (5) is, for example, in the form of a hollow cylinder provided with a bottom and is made of plastic.
• said cartridges (5) are furthermore provided with sealed closure means, of the plug or heat-sealed type, for example, which can be opened just before removing the filling product.
• the cartridges (5) of sealing product (1) can be offered for sale ready to use and disposable, that is to say, ready to be heated in the device (6) and capable of being discarded after use of the sealant which it contains.
• the device generally referenced (6 ′) essentially comprises a box (7 ′) provided with the usual controls and power supply for an electrical device (switches, on-off display indicator, timer, etc.)
• the cartridge (5 ′) is placed in a pot (13) comprising: a central housing (14) for receiving the cartridge, a thermal mass (15), respectively thermally insulating exterior surfaces (16) around the body of the pot and (17) on the upper surface of said pot.
• the thermal mass (15) is accessible towards the bottom of the pot and has a
• the insulating surface (17) forms a cap on the pot (13). It has a circular shoulder (19) which cooperates with a trigger (20) articulated on the body (7 ') making it possible to block / release the pot, possibly provided with its cartridge in the device.
• the function of the trigger is to keep the pot in its housing and, when the latter is removed, to completely close the housing to prevent dirt from entering the housing, which would disturb contact between the heating body and the thermal mass of the pot. In addition, this avoids the risk of contact between the fingers and the heating element at high temperature.
• the thickness of the trigger will be such that it can be erased under the single pressure of the pot held manually by the user.
• the thermal inertia of the mass (15) allows the user to work by leaving the device permanently and by only handling the jar and the cartridge that it contains.
• the jar and its thermal mass can be sterilized, while the doses (cartridges) can be sold sterile.
• This device is more flexible to use than that of the variant of FIGS. 1 to 3.
