[0104] The control button 7 has an elongated shaped profile allowing ease of use for the user depending on the positioning of his hand (FIGS. 2 and 3). It should be noted that the control button 7 consists of an oblong slat 7a of low thickness implanted in the upper part of the body 2 so as to come above the connection zone traversed by the thrust axis 6.

[0105] The control electronic card 4 is connected to the electric motor 5 in order to control the latter according to the control program recorded in said card.

[0106] The electronic card 4 currently comprises 6 different control programs allowing the user to perform treatments and/or injections of products with different densities in order to perform: [0107] anesthesia; [0108] anesthesia with vibration; [0109] injection of dense composite; [0110] injection of fluid composite; [0111] vibrations alone without injection; [0112] injection of liquid.

[0113] The electric motor 5 comprises a drive shaft 5a which cooperates with the thrust axis 6 by means of a connecting element 8 ensuring the transmission of the rotational force of said motor about the axis XX to the thrust axis 6 so that the latter can move in translation along said axis XX.

[0114] For this purpose, the connecting element 8 consists of a sheath 8a comprising a first internal bore 8b inside which the drive shaft 5a of the electric motor 5 is immobilized.

[0115] The sheath 8a of the connecting element 8 comprises, in the extension of the first bore 8b, a second internal bore 8c which is threaded so as to cooperate with a threaded rod 6a integral, on its outer periphery, with a thermowell 6b constituting the thrust axis 6 of the dental electronic device 1.

[0116] The thermowell 6b of the thrust axis 6 is guided in translation inside the elongated body 2 of the dental electronic device 1 so that the latter moves along the axis XX.

[0117] The elongated body 2 comprises, in its internal part, at its working end and above the thrust axis 6, a window 2d that frees access to sensors 4a integral with the electronic control card 4.

[0118] The dental electronic device 1 comprises connection means (not shown) for placing it on a charging base ensuring the maintenance and the electric charging of the battery 3.

[0119] The dental electronic device 1 comprises a range of connection tips 10 that lock inside said elongated body 2 in the extension of the thrust axis 6.

[0120] FIG. 5 shows the electronic dental device 1 with controlled thrust comprising, below the thrust axis 6 and near the connection tips 10, a vibrating device 11 connected to the electronic control card 4.

[0121] The vibrating device 11 allows the wave diffusion inside the tip in order to put it in vibration to ensure certain treatments or during the diffusion of anesthetic product, for example.

[0122] The vibrating device 11 is actuated according to the type of connection tip 10 and the associated control program contained in the electronic card 4.

[0123] The range of connection tips 10 comprises currently: [0124] A connection tip 10a for performing anesthesia; [0125] A connection tip 10b for the injection of composites; [0126] A connection tip 10c for the injection of silicone; [0127] A connection tip 10d for the injection of liquid; [0128] A connection tip 10e for vibration treatment; [0129] A connection tip 10f for the injection of dual-component composites; [0130] A connection tip 10g for filing the inter dental space by vibration; [0131] A connection tip 10h for the treatment of gums by vibration; [0132] A connection tip 10i for vibration abrading; [0133] A connection tip 10j for the dental devitalization of canals by vibration.

[0134] Each connection tip 10a to 10j consists of a hollow cylindrical body 100 comprising an internal bore 100a and on its outer periphery locking means 13 cooperating with those arranged inside the elongated body 2 located near the thrust axis 6 of the dental device 1 (FIGS. 31 to 34).

[0135] The locking means 13 consist, for example, of a quarter-turn bayonet system whose pins 13a extending from the cylindrical body 100 cooperate with housings 13b of complementary shapes formed in the inner wall of the elongated body 2 (FIG. 31).

[0136] The locking means 13 may be constituted, according to a first embodiment, of an elastically deformable system 13c comprising, on the outer periphery of the cylindrical body 100, at least two resilient blades 13d that are housed during the fastening of the connection tip 10a to 10j in a window 13e of complementary profile formed in the elongated body 2 of the dental electronic device 1 (FIGS. 32, 33).

[0137] The locking means 13 may be constituted, according to a second embodiment, of a magnet system 13f comprising, at the end of the cylindrical body 100 and on its outer periphery, a magnetically charged metal ring 13g magnetized on a magnetically charged metal ring 13h fixed inside the elongated body 2 of the dental electronic device 1 (FIG. 34).

[0138] The internal bore 100a of the hollow cylindrical body 100 comprises, on the side of the locking means 13, an opening 100b allowing passage and positioning into the connection tip 10a to 10j of the thrust axis 6 so as to be able to extract, at the opposite end of said cylindrical body, the product contained in said corresponding tip.

[0139] FIG. 6 illustrates the portion of the hollow cylindrical body 100 of each connection tip 10a to 10j comprising recognition means 12 which are activated when the tip is connected inside the elongated body 2 of the dental electronic device 1 to initialize one of the control programs previously integrated in an electronic card 4.

[0140] For this purpose, the hollow cylindrical body 100 comprises, on its outer periphery and between the locking means 13, the recognition means 12 which are positioned when locking the connection tip in front of the window 2d arranged in the elongated body 2 so that the latter come into contact with the sensors 4a of the electronic control card 4.

[0141] The recognition means 12 may be constituted by a code 12a printed on the outer face of the cylindrical body 100 which is in the locked position of the connection tip 10a to 10j, and identified and read by optical sensors 4a.sub.1 arranged on the electronic control card 4.

[0142] The recognition means 12 may be, according to another variant not shown, constituted by printing, on the outer face of the cylindrical body 100, a Tag or Rfid code which is analyzed by remote sensors.

[0143] Alternatively, the recognition means 12 may consist of studs 12b positioned in a line or in a star on the outer periphery of the cylindrical body 100, at least one of which coming into contact with the corresponding switch 4a.sub.2 when the connection tip 10a to 10j is in locked position inside the elongated body 2 (FIGS. 6 and 7).

[0144] FIGS. 7 to 10 show the connection tip 10a for the realization of simple or vibration anesthesia by means of the dental electronic device 1 according to the present invention.

[0145] The hollow cylindrical body 100 of the tip 10a comprises, opposite the first opening 100b, a threaded head 100c having in its center a small diameter hole 100d opening inside the internal bore 100a. The threaded head 100c allows the fastening of a needle holder 14, a part of the needle 14a cooperating with the hole 100d opening inside the bore 100a.

[0146] The hollow cylindrical body 100 comprises on its outer periphery a sheath 100e which can slide between an open and a closed position, covering the threaded head 100c in order to protect the needle holder 14.

[0147] The cylindrical body 100 comprises, inside the internal bore 100a and in the extension of the threaded head 100c, a cylindrical support 100f traversed by the hole 100d and allowing the tight fastening of a capsule 15 filled with anesthetic liquid and provided with a push rod 15a.

[0148] When the capsule 15 is fastened on its support 100f, it also cooperates with the portion 14a of the needle holder 14 previously mounted on the threaded head 100c of the cylindrical body 100.

[0149] Before mounting the tip 10a inside the elongated body 2, it is necessary to position on the thrust axis 6 a cylindrical plunger 100h which will be directly in contact with the push rod 15a of the capsule 15 to allow, during the translational displacement of said thrust axis 6, the ejection of the anesthetic product contained in the latter through the needle holder 14.

[0150] The connection tip 10b, shown in FIGS. 11 and 12, is designed for the injection of composites by means of the dental electronic device 1 according to the present invention.

[0151] The hollow cylindrical body 100 of the tip 10b comprises, opposite the first opening 100b, a second opening 110a enabling the positioning into the internal bore 100a of a piston 110c secured to a longitudinal rod 110d around which is placed a spring 110e for maintaining said piston within the cylindrical body 100 in the rest position.

[0152] The hollow cylindrical body 100 is secured, opposite the first opening 100b, to a double-spout body 110f having a shoulder 1102 with a hole 110h in the center which allows the passage of the rod 110d of the piston 110c.

[0153] The double-spout body 110f comprises two receiving spaces 110i and 110j centered on the hole 110h for the positioning and retention of a standard capsule 16 containing a composite material.

[0154] When the tip 10b with its cap 16 is fastened inside the elongated body 2 of the dental electronic device 1 and when the thrust axis 6 is actuated by the electric motor 5 driven by the electronic card 4, the latter penetrates inside the hollow cylindrical body 100 through the first opening 110b to come into contact with the piston 110c.

The thrust axis 6 allows the translational displacement of the piston 110c inside the hollow cylindrical body 100 so that the rod 110d of the piston comes into contact with the capsule 16 through the hole 110h formed in the spout-shaped body 110f. The rod 110d exerts a push on the capsule 16 held in the spaces 110i and 110j in order to extract the composite material contained therein.

[0155] Alternatively, FIGS. 13 and 14 illustrate the connection tip 10b whose hollow cylindrical body 100 is integral with a spout-shaped body 120a having a single receiving space 120b centered on the hole 110h and traversed by the rod 110d of the piston 110c for the positioning and retention of a double-mixing capsule 17.
