(57) Abstract:

The invention relates to medicine, in particular to prosthetic dentistry and is intended to fill the defect of the upper jaw of different origin with complete or partial resection of the upper jaw. The technical result of the invention is to eliminate the injury and the formation of decubitus ulcers of the mucous membrane of the defect, improve chewing function and providing a hermetic separation of the nasal and oral cavities with complete resection of the upper jaw, with partial resection of the edentulous upper jaw and in the case when the inlet is wider prosthetic parts when there are teeth on the healthy side. This is achieved by improving the adhesion surface of the obturator with the walls of the defect during use of the prosthesis. The essence of the invention is that resection removable denture in the upper jaw contains the obturator 1 in the form of a hemisphere, is made of elastic material and has an opening 2 at the bottom, equal to the inlet of the defect, the base of which is rigidly connected to the base 3 and the artificial teeth. The base 3 is provided with an air valve 4 with bilateral conductivity. One end of the valve 4 is connected is Lino walls, enables the stretching of the obturator in the horizontal plane And when applying air under pressure through the valve into the cavity of the obturator. On the inner surface of the obturator 1 Meridian B relative to its dome is made of the ribs 7. 4 C.p. f-crystals, 7 Il.

The invention relates to medicine, in particular to prosthetic dentistry and is intended to fill the defect of the upper jaw of different origin with complete resection of the upper jaw, as well as with partial resection of the edentulous upper jaw, and in those cases, when the input hole defect wider prosthetic parts when there are teeth on the healthy side of the jaw.

Known design resection of the denture in the upper jaw containing the prosthetic base and hollow obturator of hard plastic, which is connected with the basis narashima (see A. D. A. lubotsky. "Orthopedic care after resection of the upper jaw" in the book "Questions of dentistry and maxillofacial surgery". M 1963, pages 246-251) [1]. The prosthesis obturator is made up of surgical intervention, modeling the replacement part of the prosthesis is done arbitrarily. 3-4 weeks after the operation correction obturate the KTA. Then the gutta-percha is replaced by plastic. Fixation of the prosthesis is carried out with the help of supporting and retaining clasps, telescopic crowns, and other known elements of the clamping devices laminar or clasp dental prosthesis on the healthy side of the upper jaw, if it has teeth.

The described prosthesis performs only a cosmetic function. Chewing with this prosthesis is impossible because when chewing because of the resulting reciprocating motion of pressure sores develop and rubs are violated, and pywikipedia teeth healthy side of the jaw. In cases where the inlet of the defect wider prosthetic part or total resection of the upper jaw, the prosthesis is not fixed at all, and therefore, the chewing function is not restored, does not create a hermetic separation of the oral and nasal cavities, which leads to preservation of gnyawali and leakage of liquid food through the nose. In addition, in the case of postoperative contracture of the lower jaw of the prosthesis to enter into the cavity of the defect is not possible.

The last problem is solved in the design resection dentures, consisting of two detachable parts basis and obturator, fix the a, 1985, pp. 33-34) [2]. In other respects this construction has the same listed disadvantages.

Known as resection removable denture in the upper jaw (see S. N. Radnaev. "Prosthetics with unilateral resection of the upper jaw and no teeth" in the collection "Reconstructive surgery of the maxillofacial area", Krasnoyarsk, 1989, pages 99-102) [3], with which you can use retention points if the inlet of the defect wider prosthetic parts. Resection removable denture in the upper jaw contains a basis, to which is rigidly attached monolithic obturator is made of elastic plastic.

The disadvantage of the described construction is the inability to fully restore chewing function of the upper jaw and to create a hermetic separation of the nasal and oral cavities. This is due to the possibility of using to hold the prosthesis only some, very few expressed retention points of the defect, which is insufficient for the fixation of the prosthesis.

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 SU auth.St. 1537239 A1, class 5 And 61 With 13/00, publ. 23.01.90, bulbalay in the form of a hemisphere of the basic plastics, 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 the l-shaped pelota mounted on the obturator front for insertion into one of the lower nasal passages.

The disadvantages of the prototype are as follows.

1. The implementation of the obturator from the hard base plastic leads to injury of the mucous membrane of the defect.

2. Performing for the fixation of the prosthesis of the tides along the perimeter of the obturator create bedsores in contact with the mucous membrane of the defect, which is caused by the mismatch of the form of tides configuration of the defect.

3. The presence of pelota at one end of the prosthesis for fixing it difficult nasal breathing, and forms a lever of the first kind, fixing the prosthesis only in the front, which is insufficient to restore chewing function and promotes the formation of food bolus in the oral cavity.

4. The lack of complete sealing of the oral cavity from the nasal, due to exactly the same configuration d is the liquid food through the nose.

The objective of the invention is the creation of resection of the denture in the upper jaw, not having all these drawbacks.

The technical result of the invention is to eliminate the injury and the formation of decubitus ulcers of the mucous membrane of the defect, improve chewing function and providing a hermetic separation of the nasal and oral cavities with complete resection of the upper jaw, with partial resection of the edentulous upper jaw and in the case when the inlet is wider prosthetic parts when there are teeth on the healthy side.

This is achieved by improving the adhesion surface of the obturator with the walls of the defect during use of the prosthesis.

The technical result is achieved by resection removable denture in the upper jaw contains a basis with artificial teeth, 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 connection with tooth-cap. The obturator is made of elastic mother of the ri air under pressure through the valve into the cavity of the obturator. On the inner surface of the obturator along the Meridian relative to its dome is made of at least two ribs.

Another difference is the implementation of the obturator from elastoplast.

Another difference is that the dome of the obturator has a wall thickness of 4.0 mm

Another difference is that the obturator in place by its adhesion to the walls of the inlet of the defect has a wall thickness of 2.0 mm

Another difference is that the obturator in the remaining part has a wall thickness of 1.0 mm

In Fig. 1 shows resection removable denture in the upper jaw before joining the base with the obturator.

In Fig. 2 shows resection removable denture in the upper jaw assembled.

In Fig. 3 shows a schematic drawing of a tooth-cap in section with the valve bilateral conduction.

In Fig. 4 shows a cut in the horizontal plane of the obturator with eight ribs, where a) is the image of the obturator to blow compressed air; b) image of the obturator operable after blow with compressed air.

In Fig. 5, 6 and 7 are illustrations explaining the installation process of the obturator prosthesis in boost of the obturator through the inlet valve; in Fig. 7 shows the finally established obturator with tooth-cap.

Resection removable denture in the upper jaw (Fig.1,2) contains the obturator 1 in the form of a hemisphere, is made of elastic material and has an opening 2 at the bottom, equal to the inlet of the defect, the base of which is rigidly connected to the base 3 with artificial teeth. The base 3 is provided with an air valve 4 with bilateral conductivity (Fig.3). One end of the valve 4 is connected with the cavity of the obturator 1, and the other by threaded connection 5 - tooth-cap 6. The obturator 1 has a wall thickness that enables the stretching of the obturator in the horizontal plane (Fig. 1) when applying air under pressure through the valve into the cavity of the obturator.

On the inner surface of the obturator 1 Meridian B relative to its dome is made of the ribs 7.

In the particular case of complete denture obturator made of elastoplast and wall thickness of the dome is 4.0 mm, the wall thickness of the obturator in place by its adhesion to the walls of the inlet of the defect is equal to 2.0 mm, the Rest of the obturator has a wall thickness of 1.0 mm

For the manufacture of the prosthesis pre-SN is, in particular from the "Elastoplast", obturator with a given wall thickness. In a specific example, the thickness of the dome of the obturator 4 mm, wall thickness 1 mm obturator in place fit of the obturator to the walls of the entrance aperture of 2 mm defect Simultaneously in the manufacture of thin-walled elastic obturator on the inner surface of the obturator by polymerization of plastics place ribs 7 of hard plastic, for example, "Ftoraks".

For the introduction of the prosthesis into the cavity of the defect elastic obturator 1 with the ribs 7 is folded like a fan and injected into the cavity of the defect (Fig.4,and, Fig.5). In the cavity of the obturator 1 by means of a syringe through the valve bilateral conductivity 4 (Fig.6) when removing the tooth-cap 6 (Fig.6) to introduce compressed syringe air. When this wall of the obturator 1 is stretched in the horizontal plane, since the wall thickness is small (1 mm). But as the wall thickness of the obturator 1 in the upper part more than in the horizontal plane, it is not stretched in the vertical plane. This leads to the retraction of the obturator 1 into the cavity of the defect and retention basis of the prosthesis in the oral cavity (Fig.7).

Under the pressure of the air in the obturator valve 4 is closed and screwed the tooth-number of the no face. In the area of the ribs 7 of the wall of the obturator 1 is not stretched (Fig.4,b), and between the ribs of the wall of the obturator 1 is stretched, while the edge is drawn inside, and the walls bulge out and touch the postoperative defect cavity. Since the rib in place retracting inside the obturator does not touch the wall of the obturator, there is formed an air bag 8, which eliminates the painful sensation of fullness during use of the prosthesis and preventing pressure sores from pressure. The volume of the obturator depending on pain and for good fixation of the prosthesis can be adjusted yourself by filing or lowering of air through the valve 5.

Withdraw the obturator of the postoperative cavity should be done as follows: using a needle with a blunt end at the removed tooth-cap pressure valve 4 and the excess air is removed, then the obturator is carefully extracted from the cavity.

Clinical examples of the application of resection of the denture in the upper jaw.

Example 1. Patient A., 1947, R., operated in 1998 for cancer of the upper jaw, turned with the aim of orthopedic treatment in the clinic 5, Rostov-on-don. The patient made a full the chewing function could not be reached, as the prosthesis were not recorded in the oral cavity. On the basis of the clinic that the patient was manufactured resection removable denture in the upper jaw with a thin-walled elastic obturator, with 10 ribs and flap with two-way conduction. The obturator is made of elastic plastic "Elastoplast, and prosthetic base and ribs on the obturator plastic "Ftoraks". After fitting the prosthesis made one correction. The masticatory function of the upper jaw restored at the level of removable prosthetics. The patient himself controls the degree of stretching of the obturator depending on their senses as appropriate. Bedsores no. Foncia and cosmetic effects completely restored.

Example 2. Patient G. , 1970 R., operated in 1991 for benign tumors of the upper jaw, turned with the aim of orthopedic treatment. When viewed detected postoperative defect of the upper jaw, the inlet is wider prosthetic parts. The saved part of the alveolar ridge on the healthy side with the presence of four teeth . The hard palate and the alveolar bone, except for the foregoing portion of the alveolar ridge is absent. Patient projectors and rigidity, with valve bilateral conductivity and klammern fixation. The obturator is made of elastic plastic "Elastoplast, and prosthetic base and ribs - plastic "Ftoraks". Chewing function, cosmetic effect, foncia recovered fully, achieved a complete sealing of the oral and nasal cavity, bedsores no.

Example 3. Patient U., 1924 R., operated in 1999 for cancer of the upper jaw. In the result of the operation has the postoperative defect of the upper jaw to the right, there is a portion of the hard palate (1x2 cm and a part of the alveolar ridge at four teeth inlet in the defect already prosthetic part, but on the healthy side missing all his teeth. The patient made resection removable prosthesis with a thin-walled hollow obturator according to the above design, with three ribs and a valve with two-way conduction. The obturator is made of "Elastoplast, and prosthetic base and ribs from Veraksa". In this case, the fixation of the prosthesis is carried out only at the expense of the obturator. Restored chewing function, foncia, achieved good cosmetic effect and complete separation of the maxillary and oral cavities.
