The invention relates to orthodontics, is intended to correct the malocclusion, tooth number and positions of the individual teeth by retraction of the latter (the movement of teeth in the side of the mouth) and by applying additional orthodontic actions.

The known device retractors that contains the Palatine bone and retraction arc. The drawback of this device is that it, along with developing an active load on the front teeth, is reactive load on the rear teeth. Reactive load can lead to undesirable displacement of the posterior teeth in the mouth side.

This disadvantage is missing extraoral orthodontic appliances actions, because the reactive load distributed on the elements of the parietal and occipital poles. In addition, this device contains elements extraoral traction, front bearing and the coupling element with dentition, between which and the occipital support set of force feedback. While the front bearing, designed as a face-bow, stretched along the line of the lips and the cutting edge of the anterior teeth, which calls for the last significant tipping point there is a danger of injury to the vascular-nervous the jaw does not have this drawback, because it contains in it the front bearing is made along the line of the envelope the middle of the upper lip of the patient. Thus the insertion of the elements extraoral traction submitted in the space between the nose and the lip of the patient. This unit is the closest to the technical nature of the claimed device. It contains in addition to the front pillars and elements of extraoral traction elements parietal and occipital poles, additionally, the elements of communication with dentition. The disadvantage of the prototype is that the elements of extraoral traction contact with the skin of the patient, and when the mobility of the facial muscles may be offset extraoral traction, and therefore, the deviation vector develop its power load. Increases the probability of adverse effects of orthodontic treatment. The functionality of the prototype is limited only by the scope of the impact on the front teeth of the upper jaw. Developing this orthodontic load is purely static nature, which is not effective for the optimization of therapeutic process.

The aim of the invention is the elimination of these shortcomings.

This is because the device contains a hard unethically and dynamic loads, this site generate and display a static load is associated with the occipital support. In addition, the communication node with dentition designed as plug-in module. Site formation and display static load includes a housing located within its guides; forming a body laid input ends of the fibers; on the guides is mounted for movement along the input ends of the optical fibers by a spring-loaded stop with the light source, the output ends of the optical fibers displayed on the light Board; the housing has two adjusting rings, one of which is connected with the indicator to the zero position, and the other is associated with the spring loaded stop. Site formation and display dynamic load contains installed in the occipital pole axis with pulleys, one pulley is connected to the loop counter, and through the pulleys thrown extraoral traction, one ends fixed on extraoral base and the other ends through the load cells are connected to the arms, which are placed in the touch switches associated with the block sensorimotor commands. With the elimination of lip position of the anterior teeth of the upper jaw replacement unit made in the form of a crown with holes, through which about the form of the retaining ring, passing through the window of a reference frame, which is formed by forming longitudinal frame and transverse bushings mounted on the frame and containing a wire loop, the reference frame attached to the sagittal sleeve connected to the front pillar, through the sagittal sleeve will stretch the cable associated with the adjusting element, and the ends of the rope, envelopes side forming a frame, connected to the retaining ring.

When Troubleshooting anomalies of lip position of the third tooth of the upper jaw replaceable module contains the vestibular clamp connected to the front pillar, approximal and sphenopalatine clamps, approximal the clamp is formed of two sides of the triangular crowns, which set the base for movement in its plane, and vestibular and Palatine clamps located on the inside of the crown, and vestibular clamp rigidly attached to the base and through an adjustable rod connected to one of the corners of the crown.

In the paired sleeve 59 entered the front bearing 2, followed by bending. Bend, located at the bottom edge of the bushing 59 is a Cam 60. Between the sleeves 59 mandibular base 58 sampled (digital not specified). The location of the nodes is such that the element 53 is freely mounted in the lumen of the front pillars 2 and rests on the upper longitudinal forming a rectangular frame 57.

In the case of a managed communication with dentition site for uncoupling bite is installed on extraoral base 1 (Fig.8) on the front support 2 (Fig.8 is not shown using the support containing the guide galoa spring 64, tucked up the adjusting nut 65. On the guide cylinder 61 fixed the microswitch 66, in contact with which the rod 63 is placed on the adjustment nut 67. The rod 63 is completed the support elements 68, around the rack 69, mounted on the lower base 58.

The proposed device operates as follows. To eliminate protrusio (lip position of the anterior teeth of the upper jaw as a module, use the crown 29 (Fig.3) and the main operational nodes (Fig.1). Crown 29 without cementious set on the tooth to be moved, for example, the first right tooth (1 ). On extraoral base 1 fixed front support 2 so that the cervical region of the first tooth into the plane extraoral base 1. Thus regulate the tension of the support elements 3 on the head of the patient and the length of the elements extraoral traction 23 along the length of his hands. The formation of static load begin with the manipulation of the adjusting ring 9, the edge of which presses on the leash 18, bias the substrate 17 with the back support 19 to the back of the patient when the sensor triggers (not shown) and the light display 6 displays a dot of light output end of the fiber 16. Further manipulation to produce the adjustment is at the scoreboard 6, where is the illumination of the respective output ends of the optical fibers 16. Elements of extraoral traction 23 attached to oscam bushings 24. When periodic tension extraoral traction 23 produced by the patient with the help of knobs 27, is offset from the extraoral base 1 relative to the occipital support 19, with the front bearing 2 with the crown 29 has on roaming tooth retraction action. This dynamic effect occurring on the background of the static load, is controlled by the block sensorimotor commands 28. Block 28 pre-adjusted and gives the patient the rhythm of the hands: the signal switching diodes (communication) indicate the period of rise of the load, the period of its exposure and the period of its discharge. Readings of the dynamometer 26 and the loop counter 22 provides information to the orthodontist. Thus, the patient uses the device with the installed static load, for example, 2-3 hours a day for 1-2 months. The static load enhances the action of dynamic loads, implemented in the form of sessions under the supervision of a physician. Instead of crowns 29 can be used in the node shown in Fig.4. While the retaining ring 31 is connected to the first tooth 1 and tighten, Ormerod element 38 along the contours of the gingival margin of one or more of the front teeth (depending on the evidence, with vestibular side, and at the cutting edge of the wire goes to the palatal surface of the tooth (1 ). The wire element 38 includes a transverse sleeve 34. Through elements 37 this node connects to the front pillar 2, which is fixed on extraoral the base 1, and then perform steps similar to the above.

Thus the nodes of the formation and display of loads through extraoral base 1 is putting pressure on the front support 2. From the front supports (2) the pressure through the sleeve 36 and sagittal sleeve 35 is transmitted to the supporting frame 33, and from it to the tooth on which is placed the retaining ring 31 and the wire element 38, is placed in a transverse sleeve 34. The element 38 depending on the configuration passes the pressure on the cervical part of one or more teeth. Thus therapeutic load directed toward the mouth.

When gubna position of the third upper tooth used the site shown in Fig. 5. Preliminary fitting of the node to the tooth lies in the fact that vestibular 40, approximal 41 and sphenopalatine 43 clamps mounted on the respective anatomical parts of the tooth. Triangular crown 41, is made as of approximal clamp, wear on the teeth, and stretch marks 44 are tightened to BA is Lamento adjust thrust 36, it is shown in Fig.4) with approximal clamp 41 is shifted to the vestibular clamp 40 and covers the tooth approximal sides, then into the slots 47 enter the front support 2 and attach it to the extraoral the base 1 so that the cervical part of the roaming tooth into the plane extraoral base 1.

The formation of static loads, as well as other therapeutic actions produce similar actions produced in clinical cases. While the front bearing 2 transmits the pressure through the intermediate elements 45 on the vestibular clamp 40, which pressurizes the tooth, displacing it in the dentition. In the case of clinical indications for distal movement of the fourth upper tooth, for example, to a remote location fifth baby tooth, use the node shown in Fig.6. The grippers 51 sets with the buccal and palatal sides of the fourth tooth plate 52 move in his direction to the state of the fixation site on the tooth, then the front support 2 is connected with extraoral base 1. Then the form loads, putting pressure on the front support 2. From the front supports (2) the pressure is transferred to the grippers 51, bias the fourth upper tooth to a remote location fifth baby tooth is Fig.7), fitted at extraoral database 1: the node to divide the bite hold on sleeves 24, into which is injected a rectangular frame 57, and the ears of these bushings fix the ends of the elements extraoral traction 23, which is transferred through the hooks of the sleeves 56. The length of the traction elements 23 regulate the coils 25 along the length of the patient's hands. Site for retraction of the lower teeth so that the guide element 53 were located in the lumen of the contour of the front support 2. Mandibular base 58 mounted on the occlusal surfaces of the dentition of the lower jaw, and the plunger 60 is led to vestibularapparat part of the lower cutter, and then adjust the elements of the parietal supports 3 and form a static load (as described), on the background of the static load is the formation of dynamic loads similar to those described cases. When the static load extraoral base 1 is shifted toward the occipital pole 19 and the front bearing 2 with the plunger 60 has a retractive action on the lower cutter. Dynamic load actuates the linkage site to the dissociation of the bite. In this guide element 53, as a lever with a bearing axis on the longitudinal forming a rectangular frame 57, plementa 53 experiencing jet action transmitted on extraoral base 1 and fixed on its front support 2 with its plunger 60. Thus, the retraction action of the follower 60 on the lower cutter is enhanced. In this process, the components are present in the form of periodic contractions of the masticatory muscles, whose strength can be controlled by the managed node communication with dentition (Fig.8).

To set this node to divide bite containing a rectangular frame removed, and the site shown in Fig.8, fixed on extraoral base 1, setting it on top of the front support 2 (Fig.8 not shown). The rod 63 connected to the mandibular base 58, with fixed thereto hour 69 encircles the support element 68. Mandibular base 58 is placed in the oral cavity of the patient, then, by manipulating the knob 62, achieve alignment plane of the support element 68 with the palatal surface of the Central incisor of the upper jaw (the cutter is debnam abnormal position). The patient is instructed to maximally compress the teeth, the incisors of the upper jaw passes the pressure on the supporting element 68, and the rod 63 will move into the oral cavity. By manipulating the adjusting nut 65, minimize the stroke at maximum compression of the teeth. Then down roushie elements is possible in the case when the force of contraction of the masticatory muscles of the patient reached the maximum, in this case closes the circuit of the microswitch 66 and will light the led channel feedback, located on the front Board block sensorimotor commands 28. As a result, a signal, following which the patient activates the function of the masticatory muscles and exerts maximum pressure on the abnormally located Central incisor of the upper jaw, and contributes to a more successful elimination of anomalies Along with this, when shifting in the direction of the rod 63 is compressed spring 64 and increases the load on extraoral base 1, and through it to the front pillar 2 and the pusher 60. Thus, simultaneously with the action of the upper tooth retraction increases the effect on the bottom.

The proposed device minimizes the side effects of traditional orthodontic loading, as the load is applied in the cervical area roaming tooth, reduces the overturning moment and eliminates the danger of injury to neurovascular bundle at the apex of the tooth root.

The device with its sites on a hard extraoral base does not touch the skin of the patient, therefore the mobility of the facial muscles does not affect the Deposit account opened more adequate therapeutic effect and is a great convenience for the patient.

The proposed device has a reserve of forming a therapeutic load: static load is combined with a dynamic load; load indication and possibility of its activation in the system managed communications and so on, i.e., the proposed device is effective remedy for multidisciplinary impact in the elimination of dento-maxillary anomalies.

The proposed device through the use of plug-in modules has a large range of functional activities than similar known device. The proposed device is uniform. In contrast to the process it is used without pre-casts, fittings, etc.
