The invention relates to the field of medical engineering, in particular to dental devices. It is intended for the elderly, lost teeth, and replaces the last, i.e., allows full grinding of food.

Many dental devices are composed of u-shaped bearing base. This is caused by the need to simulate the shape of the jaws of the patient. Such devices, in particular, is dantesco - invention of the author of this proposal author.St. Abi with the features of the proposed device. However, the purpose of genoscope somewhat different from the purpose of this device. Therefore, genocop can be seen as a distant cousin.

The known device, replacing the natural teeth - single and multiple restorations. In fact, this artificial teeth fixed in the oral cavity of the patient on his left intact natural teeth. Or in the case of absence of the latter are fixed on solid grounds (on the artificial jaws). The first case is preferable, because then the dentures are functionally complete, and are almost exactly like natural teeth, are not inferior to them. But for the elderly with a single surviving natural teeth or a complete lack thereof have to use removable dentures on artificial jaws despite their annoying flaws. The essence of these dentures is as follows.

Creates a suction (vacuum) to the palate with a plastic plate. Its configuration is the same as the configuration of the sky, which leads to the suction effect as mounting phenomena. On the outer edge of this hard plate (it is thickened, has a horseshoe shape and plays the role of the upper jaw) is rigidly fixed to the number of the suit is massova arc. Its lower surface, suction to the bottom, the same as the configuration tubenoses surface of the lower jaw. This ensures that the suction effect of the lower denture to the alveolar surface. The upper part of the arc covered with artificial teeth.

Data dentures are the prototype of the claimed invention. They are not effective, and their use is accompanied by painful sensations. The reasons for these shortcomings are as follows:

- suction surface RUB the mucous membrane of the palate and sobnosky plots in both jaws (especially when eating);

- previous disadvantage is amplified by the unattainability of the ideal bodily match and plastic surfaces, providing the suction. Moreover, from the jaws protruding fragments of the former teeth or roots that prevent adhesion. These fragments before the prosthesis should be removed, which is painful and not all patients will agree to thereby subject themselves to the pain of dentures made with incomplete suction effect;

- bearing plate dentures should be thin (no thicker than 2 mm). But because they are brittle;

- the use of metal instead of plastic in this technology pelucchi as nails), etc. painful and therefore rarely used.

These drawbacks determine the need for a fundamentally new way of prosthetics. This is what provides the claimed product. It is free from the drawbacks of the existing prostheses described above.

The essence of the invention is that the characteristics of the prototype (the presence of two arcuate bearing bases with rigidly fixed on them a series of artificial teeth on the locking surfaces, and configuration of the bases follows the shape of the alveolar processes of the respective jaws) supplemented distinctive features: the presence of mutual connection of adjacent ends of the bases, and the ends (one or both) are cross bridge, through which (Oh) ends movably connected, so the Central part of the grounds can move towards and apart from each other vertically; the last action performed automatically due to the presence of springs, pushing the base toward each other; at the base is a guide extensions leading tangentially to the inner surfaces of the alveolar processes of the jaws of the patient, and this limits the backlash and offset ustroistvo soft cushioning pads.

The introduction of the distinctive features is intended to provide a solution to:

- elimination passively (along with the traumatic) a denture in the mouth.

- eliminate smexiest upper and lower limb bases relative to each other horizontally, thereby eliminating nesovpadaet the occlusal surfaces of opposing teeth relative to each other;

- providing semi-automatic mode chewing

- providing the perfect congruence of the occlusal surfaces of opposing teeth,

- to reduce the invasiveness of the contact device with the mucous membrane.

The solution of these problems is provided distinctive features as follows. The connection ends of both prostheses provided an intimate connection of the prosthesis in a single device. This unity gave the device volume and thus created the possibility of functional fixation of the device in the mouth entirely as a single conglomerate. The presence of arching springs gave the device a state of constant maximum volume that holds the device in the oral cavity due to the fullness inside her. Due to this fixation is achieved the possibility of refusing the ASS="ptx2">

The use of compounds of moving vertically and together with the fixed horizontally to the ends of the prosthesis, provided the dentures nameselect relative to each other horizontally and gave the best sovpadaet chewing surfaces. That is, provided their full congruence and thereby improves the quality of chewing.

Application arching springs provided the automaticity of expanding the top and bottom of the device while opening the mouth. This is beneficial for both mentioned volumetric fixation device in the mouth, and to a General feeling of lightness act of chewing that care for older persons.

The use of soft pads provides atraumatically and comfort of the contact device with the mucous membrane.

Thus, these distinctive features are useful, give a new positive result. They do not occur in the prototype and its analogues, which allows to consider these new signs.

In Fig. 1 depicts the inventive device (hingeless option), front view. In Fig. 2 - side view. In Fig. 3 - in swivel modification, side view. In Fig. 4 is a top view.

Removable pads lei and nodes, in functional-structural unity. Horseshoe-shaped (arcuate) bearing base 1 and 2 are mapped so that their subopcode surface are adjacent and smykanie.

Grounds 1, 2 and the teeth 10, 11 (as well as all other teeth) made of durable hard plastic or stainless steel. Strip covering the upper outer surface of the guide appendices 3, 4, 9 and lower outer surfaces of the guide appendices 6, 7, 12, made in the form of plates of microporous rubber or foam rubber, is fastened to the processes of glue plasma and because of their simplicity, the thumbnails are not shown.

Springy plate 5, 8 or springs 13, 20 tend to push the base 1, 2 relative to each other. Moreover, in a hinged embodiment (Fig. 3,4) extracting accompanied by movement of the ends of the bases around the axes 16, 17, 18, 19 in the areas of mobile connections 14,15. In hingeless variant (Fig. 1,2) extracting grounds 1, 2 is due to the extension spring plates 5,8.

Cross bridge 23 of the ends of the bases can be performed in a spring form, i.e. of the spring plates 5, 8. In this case, the previously mentioned spring 13, 20 and screw connections 14, 15 in the construction of isdel is standing.

One of the functional joints 14, 15, namely the joint 15 connects a gap between the substrate 2 and the crosspiece 23 (Fig. 3). The presence of joint 15 provides congruence - sovpadaet teeth of the upper and lower row of bearing bases.

The use of pads next. Clean washed with soap (or disinfecting solution) the device according to Fig. 1 is compressed by the force of arms vertically, reducing the base 1, 2 to the closed state, as shown in Fig. 2. Then spring 8 forward device vidvigayt in a widely opened mouth of the patient and let him go for independent automatic retraction. Thanks to the guide appendices 3, 6, 9, 7 and 4, 12 (21, 22) the unit yourself focused in the mouth, taking the correct working position. In cases of insignificant deviations from this position it is restored minor correction efforts of language. In the future, the patient has the ability to reduce the base 1, 2 masticatory muscles and thereby clamping the upper and lower dentitions. The breeding grounds are made automatically through the efforts developed by the springs 13, 20 or plates 5, 8. Thus is achieved the ability to make voice funktsii to free the mouth of the lining, the patient can move the base 1, 2 with the thumb and index fingers, then pull the pads entirely out of his mouth.

The advantages of the inventive device in comparison with the prototype are: the almost complete absence of trauma mucous membrane of the mouth during use, the ability of the patient to perform self-service without having to resort to paid services of a dentist (you don't need a very complicated procedure of fitting and fits dental prosthetist for a considerable fee, comparable to the price of our products); full nesmachivaemost products (steel version), no need to purchase new products other configurations as resorption of the alveolar processes of the patient, improving quality and speeding up the process of mastication due to the perfect sovpadaet chewing surfaces of your dentures, simplicity of operation of the device. These advantages create significant quality and economic efficiency of the invention.

Thus, our product more attractive to patients, their superior performance characteristics than the prototype. It is quite technologically advanced: for its production does not require the development of new Neizvestny absence of teeth, consisting of a u-shaped bearing bases with artificial teeth to adjacent contiguous surfaces, the ends of the bases are connected in pairs by transverse vertical jumpers with the possibility of providing mobility of the bases relative to each other vertically and immobility horizontally, characterized in that the ends of the bases are connected by jumper by hinges, ensuring congruence bite.

2. The prosthesis under item 1, characterized in that between the ends of the bases on each side of the front swivel posted by spring planting bite.
