The invention relates to medicine, in particular to prosthetic dentistry and can be used for prosthetic teeth in the upper jaw when the flaws in the area of the alveolar ridge.

The known method of dental prosthetics in the defects of the alveolar part of the maxilla, not penetrating into the maxillary sinus, in the presence of estelles with a larger number of abutment teeth, duplicate dentition and artificial gums (Kostur B. K., Minyaeva Century A. "Maxillofacial prosthetics", Leningrad: Medicine, 1985, S. 17).

The disadvantage of this method is that it is not possible to effectively eliminate the imperfection of the face of the patient when the retraction of the soft tissues of the upper lip caused by such defects as: narrowing of the dentition relative to the bottom, the offset in the palatal side; the underdevelopment of the upper jaw, the lower height of the bite in the Central occlusion (e.g., teeth grew, and the alveolar underdeveloped), etc., Artificial gums in a known way prosthesis brings in the way the disadvantages of dentures, and it provokes the atrophy of the alveolar ridge. In addition, the design of the prosthesis, made in a known manner, makes it difficult, and in some cases makes it impossible hygienic care, difficult to repair and require removal when necessary dental treatment under the crown. All of the above reduces the physiology of the prosthesis, made famous by way of the prosthesis, and therefore the physiology of way.

Thus, identified as a result of a patent search method dentoalveolar p is a technical result, consisting in the increase of physiology and improve outcomes restore the aesthetic appearance of the face of the patient when the retraction of the soft tissues of the upper lip caused by such defects as: narrowing of the dentition relative to the bottom, the offset in the palatal side; the underdevelopment of the upper jaw, the lower height of the bite in the Central occlusion (e.g., teeth grew, and the alveolar underdeveloped), etc.

Closest to the present invention is a method of dental prosthetics at the flaws in the area of the alveolar ridge of the upper jaw, which entail zapadenia soft tissues of the cheeks or lips. In accordance with the method produces a full denture, what is it used for prosthetics with splinting of teeth, and aesthetic appearance of the patient recover, forming a thickness in the vestibular part of the prosthesis (C. K., Koster, C. A. Minyaeva "Maxillofacial prosthetics", Leningrad: Medicine, 1985, p. 16).

The known method subcellular prosthesis has disadvantages inherent in the methods of prosthetic dentures, namely: reliance on tissue prosthetic bed and transmission of masticatory pressure on the gums will eventually lead to atrophy Kosice prosthesis reduces its strength and in addition, increases the mobility of natural teeth. Rigidity is even more reduced when the prosthesis in terms of violations of occlusion, when the conditions for fixation of removable prosthesis violated. All this reduces the physiology of the identified method of prosthetics. In addition, the identified method does not allows to eliminate the imperfection with the retraction of the soft tissues of the upper lip, such as narrowing of the dentition of the upper jaw relative to the lower offset in the palatal side, with the underdevelopment of the upper jaw, etc. Physiology known way prosthesis reduced so from what used dentures take up much space in the mouth and require the placement of the elements of the prosthesis in the region of the hard palate. The latter causes some patients gag reflex, requires adaptation to the prosthesis.

Thus, the identified closest to the proposed method of dental prosthetics in the defects of the alveolar part of the maxilla when the implementation does not ensure the achievement of the technical result consists in increasing physiology and strength of implants made this way, and also in improving rezultacie defects, as the narrowing of the dentition relative to the bottom, the offset in the palatal side; the underdevelopment of the upper jaw, the lower height of the bite in the Central occlusion (e.g., teeth grew, and the alveolar underdeveloped), etc.

The present invention solves the problem of creating a method of dental prosthetics in the defects of the alveolar part of the maxilla, which ensures the achievement of the technical result consists in increasing physiology and strength of implants made of the proposed method, and also in improving outcomes restore the aesthetic appearance of the face of the patient when the retraction of the soft tissues of the upper lip caused by such defects as: narrowing of the dentition relative to the bottom, the offset in the palatal side; the underdevelopment of the upper jaw, the lower height of the bite in the Central occlusion (e.g., teeth grew, and the alveolar underdeveloped) etc.

The essence of the invention lies in the fact that in the way of dental prosthetics in the defects of the alveolar part of the maxilla, including splinting teeth and manufacture of removable backup dentition, chinaroot teeth that are not in occlusion, which of manufacturing the beams, then make a hollow cast metal frame in the form of the outer telescopic crowns and connecting beams, congruent splinting designs, with beams splinting designs rigidly fixed Patricia attachments, and on the beams of the frame are rigidly attach the corresponding matrix attachments, then made removable duplicate set of teeth with artificial gum made from plastic, with artificial gingiva is made on the skeleton and teeth are set on grounds of orthognathic occlusion, after which the frame is put on splinting design and fixed it by combining matrices and corresponding Patric attachments, geometrical dimensions of the crowns and beams of the frame is chosen so that the frame tightly worn on splinting design.

The technical result of the proposed method is achieved due to the fact that it involves a combination of removable and fixed prosthesis that allows you to combine the positive qualities of both methods of prosthetics. This is achieved as follows. In the proposed method is used as a support teeth that are not in occlusion. What they chinaroot and splinting design is in the form of telescopic crowns with rigidly connecting beams. Splinting of the abutment teeth of the proposed method captures the teeth, bringing them together in a hard arc, provides rigidity and durability of the prosthesis. The Association of the teeth in a single system unloads them parodont and redistributes the masticatory load on all the teeth, which increases the physiology of way. The manufacture of the frame, congruent splinting designs, which subsequently make artificial gums with the attached teeth, provides the possibility of using the proposed method removable backup dentition. However due to the fact that the removable duplicate set of teeth fixed on splinting design, it relies on the teeth. This provides a natural mechanism for transmission of masticatory pressure on the tissue of the alveolar process and eliminates the harmful effects of denture supporting tissue that prevents atrophy of the alveolar process and increases the physiology of way. Due to the fact that the geometric dimensions of the crowns and beams of the frame are made so that the frame tightly worn on splinting design, virtually eliminated the horizontal offset of the removable part of patuvania teeth and lengthens the period of use of the prosthesis. All this increases the physiology produced offered by way of the prosthesis, but also increases its durability. Reliable retention of the frame by splinting designs and rigidity removable backup of the dentition in the Assembly are provided, in addition, the rigid connection of their castle mount, which on the beams splinting designs rigidly fixed Patricia attachments, and on the beams of the frame - corresponding matrix attachments and by combining matrices and corresponding Patric is rigidly fixed on the abutment teeth of removable backup dentition. Using the proposed method plastic artificial gums, as well as the manufacture of hollow frame facilitate the removable part of the prosthesis construction, which increases the physiology of the prosthesis, made of the proposed method. In addition, the use of plastic artificial gums improves the aesthetic appearance of the face of the patient. Due to the fact that the duplicate row of teeth at the gum set on the grounds of orthognathic occlusion, restore occlusion. Since the dentition of the maxillary denture is a reference to the soft tissues of the upper lip, visually increases the size of the middle third of the face to nonopiate affects his psychological status. Restoration of occlusion also provides recovery of articulation points, important in the formation of sound and chewing function, which also increases the physiology of the proposed method prosthetics.

In addition, there is a method allows you to use the prosthesis, without touching the sky that does not cause gagging. However due to the fact that the hard palate is open, not broken tactile, gustatory and thermal sensitivity. All this increases the physiology of the proposed method prosthetics.

Thus, due to the fact that in the proposed method, the dental prosthesis when the defects of the alveolar part of the maxilla receive a combined denture removable duplicated dentition, which is fixed on the fixed part of the prosthesis splinting structure of teeth, non-occlusion, and are fixed to each other by means of attachments, eliminates some disadvantages of removable prosthesis, and it provides support removable part of the prosthesis to the natural dentition, which provides a natural mechanism for transmission of masticatory pressure on the tissue of the alveolar process; recovering occlusion; ensures the durability of the prosthesis; use for fixation of removable backup of the dentition of a hollow frame, congruent splinting designs, and the use of key fasteners (male mould, matrix attachments) provides reliable fixation of the prosthesis when the occlusion, as well as easy installation; with easy installation and removal of the prosthesis excludes the possibility of injury at this; the sky is still open, which facilitates the process of adaptation to the prosthesis (reduces the likelihood of a gag reflex), preserves the tactile, temperature, taste sensitivity; the ability to remove duplicate dentition facilitates the hygienic care of teeth and gums and, if necessary, facilitates repair, correction of the prosthesis, replacement of artificial teeth out of the mouth of the patient.

Thus, implementation of the proposed method of dental prosthetics in the defects of the alveolar part of the maxilla provides the achievement of the technical result consists in increasing physiology and strength of implants made of the proposed method, and also in improving outcomes restore the aesthetic appearance of the face of the patient when the retraction of the soft tissues of the upper subsuite the upper jaw, reducing the height of the bite in the Central occlusion (e.g., teeth grew, and the alveolar underdeveloped), etc.

In Fig. 1 shows a removable dental prosthesis for the upper jaw, made in accordance with the proposed method, the view from the oral side of Fig. 2 - splinting design for abutment teeth; Fig. 3 is a view of the removable part of the prosthesis from the teeth;

Dental prosthesis made in accordance with the proposed method contains a removable backup dentition 1 and splinting design 2. Duplicate tooth row 1 contains the plastic gum 3, artificial teeth 4 mounted on it on the grounds of orthognathic occlusion and the frame 5. Desna 2 is rigidly fixed on a metal frame 5, which with the use of prosthesis wear splinting structure 2 of the abutment teeth. Splinting structure 2 made of a metal, cast in the form of telescopic crowns 6 is rigidly connecting beams 7. The frame 5 is made congruent splinting designs 2. The frame 5 is hollow, cast in the form of the outer telescopic crowns 8 and connecting beams 9. The geometric dimensions of the crowns and beams of the frame 5 is selected in such a way that it was put on shinich 9 frame 5 - matrix 11 attachments.

The method of dental prosthetics in the defects of the alveolar part of the maxilla perform the following way. Chinaroot teeth that are not in occlusion. This is made of metal cast splinting structure in the form of telescopic crowns with rigidly connecting beams. Then make a hollow cast metal frame in the form of the outer telescopic crowns and connecting beams, congruent splinting designs. On the beams splinting designs attach Patricia attachments, and on the beams of the frame - corresponding matrix attachments. After this is made removable duplicate set of teeth with artificial gum made from plastic. When this artificial gum made on the skeleton and teeth are set on grounds of orthognathic occlusion. Assembly frame put on splinting design and fixed it by combining matrices and corresponding Patric.

The dental prosthesis is made specifically for each case. One of the options shown in Fig. 1 to 3. Chinaroot teeth that are not in occlusion, and if the patient has teeth missing height to occlusal bite - they also wear crowns the s series. After preparation of the teeth of the upper jaw is made congruent splinting designs 2 hollow metal cast frame 5. For good adhesion of the armature 5 with plastic artificial gums 3 the surface of the frame cover the metal crystals. Patricia 10 and the plates 11 attachments installed in several places on the basis of the location klammern line. Then in the usual way in occludator produce a duplicate tooth row 1. On the frame 5 of the removable part of the prosthesis is made of artificial gingiva 3 of plastic material in the missing volume of the alveolar ridge. The teeth 4 are putting on the grounds of orthognathic occlusion. Ready duplicate set of teeth 4 with the frame 5 and attachments 10, 11 fixed on splinting design 2 teeth that are not in occlusion.

When implementing the method can be used, for example, multiple push-button attachment VKS-SG company Bredent.
