The inner wall 9 of the chamber 7 is the wall of the obturator 1 and has a shape similar to the outer surface of the chamber 7. 4 Il.

The invention relates to medicine, in particular to prosthetic dentistry and is intended to fill the defect of the upper jaw of various etiologies with resection of the anterior and upper walls of the maxillary sinus, when the formation of extensive keloid scars soft tissue component of the buccal region and sockets.

Known design resection of the denture in the upper jaw (see S. N. Radnaev "Prosthesis with unilateral resection of the upper jaw and no teeth" in the collection "Reconstructive surgery of the maxillofacial area", Krasnoyarsk, 1989, pages 99-102) [1], comprising a base, to which is firmly attached monolithic obturator is made of elastic plastic, which is used for partial restore chewing function defects top Celestia patient keloid scars soft tissue component of the defect of the upper jaw with anterior resection and the upper wall of the maxillary sinus due to the fact, what keloid scar and solid obturator made of elastic plastics are rigid in its structure.

The closest structural performance to the present invention is a prosthesis for the closure of the sky after complete resection of the upper jaw (see A. C. SU 1537239 A1, M CL 5 And 61 With 13/00, published 23.01.90, Bulletin 3)[2], taken as a prototype.

The prosthesis includes a base with artificial teeth, obturator, made in the form of a hemisphere of the basic plastic material, the base of which is rigidly connected to the base of the prosthesis. The configuration of the obturator after complete resection of the upper jaw is fully consistent with the configuration of the defect. Fixation of the prosthesis is carried out by the tides along the perimeter of the obturator and G shaped pelota mounted on the obturator front for insertion into one of the lower nasal passages.

The disadvantage of the prototype is that it cannot be used when a patient has a keloid scars soft tissue component of the defect of the upper jaw with anterior resection and the upper wall of the maxillary sinus due to the fact that the keloid scar is quite rigid in its structure.

When lifting and holding the-breaking scars relatively rigid frame is the friction, causing wounds and bedsores defects in the buccal region and sockets.

The objective of the invention is the creation of resection dentures, allowing you to completely eliminate friction keloids soft tissue component of the wall of the obturator, the motion of facial muscles (when eating, laughing and so on).

The technical result of the invention is to eliminate friction keloids soft tissue component on the surface of the obturator resection prosthesis in the upper jaw, by providing simultaneous movement of the surface of the obturator and the surface of the soft tissue component with keloid scars when working mimic muscles of the patient.

The technical result is achieved by the fact that in the known resection removable denture in the upper jaw, contains the basis of the artificial teeth and the obturator, the base of which is rigidly connected with the base, made in the form of a hemisphere and a corresponding configuration of the defect, according to the invention a base provided with an air valve with two-way conductivity, one end of which is connected with the cavity of the obturator, and the other by threaded connections, with tooth-cap. The obturator is equipped with a hole in the lower part, wherein located at the Meridian on its dome. The obturator is equipped with a chamber filled with a gel-like bioinert mass. The outer surface of the chamber adjacent to the defect jaw has a shape that mirrors operable spatial configuration of postoperative defect, and the inner wall is the wall of the obturator and is in working condition shape similar to the outer surface of the camera. The obturator and Luggage made of thin-walled elastic material.

The camera surface with elastic walls, filled with a gel-like mass, in working condition repeats the spatial configuration of the defect and therefore tight to soft tissue component with keloid scars defect. Therefore, when working the facial muscles, there is a simultaneous movement of the camera along with the soft tissue relative to the obturator, which is set on the basis of the prosthesis still. This friction force is transferred to the gel layer and distributed it in the gel layer transfers the force of friction on the surface of the fixed obturator, which eliminates friction on the outer surface of the camera, and therefore, the appearance of wounds and ulcers of the soft tissues of the t (vertical section).

In the figure 2, 3 and 4 show schematic drawings explaining the installation process obtenerse part of the prosthesis into the cavity of the defect, where the figure 2 - introduction obtenerse part in the cavity of the defect, on the figure 3 - the process of forcing air into the cavity of the obturator through the inlet valve, figure 4 shows the finally established obturator with a chamber filled with a gel-like mass in the cavity of the defect.

Resection removable denture in the upper jaw with resected front and top walls of the maxillary sinus (Fig.1) includes an elastic thin-walled hollow obturator 1 with an opening 2 at the bottom, equal to the inlet of the defect jaw, the base of which is rigidly connected to the base of the prosthesis 3. The prosthetic base 3 with artificial teeth provided with an air valve 4 with a two-way conductivity, one end of which is connected with the cavity of the obturator 1, and the other through the prosthetic base 3 by means of screw connections to the tooth cap 5. Wall of the obturator 1 is equipped with at least two ribs 6, located at the Meridian on its dome. The obturator 1 is equipped with a camera 7 with elastic 8 outer wall and filled with a gel-like bioinert mass. Poverhnostnoaguoe postoperative defect. The inner wall 9 of the chamber 7 is the wall of the obturator 1 and is in working condition shape similar to the outer surface of the camera.

Resection removable denture in the upper jaw mounted in the cavity of the defect as follows: remove the tooth cap 5 with threaded connections valve 4 (Fig.2). The obturator 1 together with the chamber 7 filled with a gel-like mass is compressed in the horizontal direction so that the magnitude of the obturator 1 together with the chamber 7 does not exceed the value of the input apertures of the defect, and injected into the cavity of the defect, and the Foundation of the prosthesis 3 establish into place in the mouth.

Then using a syringe pump air through the valve with two-way conductivity 4 into the cavity of the obturator 1 (Fig.3). When this elastic thin wall 9 of the obturator 1 is stretched, the obturator increases in volume and, since the outer wall 9 of the obturator 1 is the internal walls of the chamber 7, when the stretching of the walls of a gel-like mass of the camera, respectively presses on the outer wall 8 of the chamber 7, stretching her and filling the spatial configuration of the postoperative cavity, this creates a uniform pressure at all points of the defect. Then the tooth cap 5 connected to the valve DFCS is hero 7, repeats reliefwartrol spatial configuration of postoperative defect and the outer wall 8 of the chamber 7 adjacent to the walls of the defect, when the movement of facial muscles and postoperative scarring of soft-tissue component, there is a simultaneous movement of the camera 7 with a gel-like mass with respect to the obturator 1. Therefore, the friction of the soft tissues on the outer wall of the chamber 7, as the camera 7 moves together with soft tissues, therefore RUB sores, bedsores, wounds, soft tissue and scarring does not occur.

Remove the denture from the mouth can be as follows. The tooth cap 5 is removed from threaded connection with a needle with a blunt end, the valve opens with bilateral conductivity 4, removes the air and the obturator is removed from the cavity of the defect of the upper jaw.
