The invention relates to medicine, in particular dental, and can be used to restore volume to the hard tissue and fill the defects of the dentition before the final prosthesis.

The recovery of the amount of solid tissue and supplying the defects of the dentition crowns of any type of metal, ceramic, plastic, combo, etc. is the most common way to restore chewing efficiency, aesthetics and prevent the development of dental anomalies and deformations in prosthetic dentistry.

An important stage of dental prosthetics crowns and bridges is the use of temporary crowns on the stage in the production of permanent structures, and also to prevent the development of dentofacial deformities. The manufacture and use of temporary makeshift crowns provides functional stability of the dentition (occlusive, phonetic and aesthetic) and the prevention of periodontal disease by restoring the anatomical contour of the clinical crown, and prevents irritation of the gingival margin (Zakharyan LO, 2011). After carrying out orthodontic realignment before committing permanent fixed structures for the prevention of relapse of the deformity red who needs to make the retention of the prosthesis, not allowing for the development of deformation dentition due to the absence or destruction of the teeth (Gavrilov E.A., 1984). However, quite often, clinicians ignore temporary crowns due to the high cost, complexity of manufacture, or to save their own time. However, the manufacture of improvised constructions, complementary defects of dentition at the time of manufacture of the permanent prosthesis, sometimes, indeed, raises a number of difficulties. The greatest difficulty is filling defect of dentition with tooth that are located in different anatomical planes: frontal and sagittal (front and side teeth departments). Multidirectional vectors acting on the denture during chewing, often lead to fracture of the provisional restoration at the junction of acrylic or composite crowns, the most commonly used in dentistry as temporary. And to create the aesthetic effect of the crown after fitting need to be refined in the laboratory, which is extremely time-consuming.

There is a method of temporary crowns by removing the stamp from the dentition, preparation of the abutment teeth and overlay seal with plastic cold polymerization on the prepared teeth (Kalamkarov HA Orthopedic treatment with the use of metal-ceramic prostheses. Honey is Aspera, 1996, page 53).

A significant drawback of this method is the fragility of the resulting structures and, consequently, a high risk of fracture design. Low aesthetics is not possible to use these crowns in the anterior.

Known a better way of temporary crowns by obtaining Invisalign to further amendments of the composite, with its subsequent polymerization. Then Kappa is removed (see RF patent №2402994 prototype. The method of restoring the occlusal surfaces of the chewing teeth group includes the manufacture of celluloid plate mouthguards on the number of teeth obtained by pressing in a vacuum apparatus model of the jaw of the patient after preparation of the problematic tooth restored dental wax using an automated analysis system bite T-Scan, consistent with the principles of modern gnathology, with subsequent submission to the Kappa bioinert composite material, it locks on the row of teeth and polymerization.

The disadvantages of this method include the fact that the crown, thus obtained, is as fragile and prone to breakage. The process of separation of the mouthguard after polymerization causes considerable difficulty in clinical practice and requires long-term improvements in the oral cavity. This method cannot be applied for manufacturing is the service temporary crowns after conducting orthopedic or orthodontic tooth movement. This is due to the fact that acrylic plastic has no practical elasticity and firmness on the break and in conditions not fully stable dentition quickly breaks down or raspoliruyte.

Thus, there is a need to create temporary crowns high strength and aesthetics that are installed on the teeth located in the same plane and in different anatomical planes, able to compensate for a defect of dentition, to stabilize the dental system after elimination of dentoalveolar deformities, and to prevent relapses. All this leads to improved efficiency in orthopedic treatment and is the object of the present invention.

Delivered to the invention this object is achieved by a combination of known characteristics, such as the fabrication of the plaster model of the dentition with the subsequent manufacturing of the mouthguard of cellulose plastics, obtained by pressing in a vacuum apparatus model of the jaw of the patient, cutting mouthguard on gingival line of restored teeth with subsequent submission to the Kappa bioinert composite material with fitting and polymerization, and new signs, namely, that on the plaster model carry out the filling of the defects of the dentition using artificial acre the new teeth to their pre-fixation on the model in the field of defects, then after fabrication of mouthguards with fixation of artificial teeth by compression of the teeth mouthguards with drawing on the inner surface of the artificial acrylic teeth pink elastic plastic and fill the inner surface of the mouthguard in the area treated teeth self-hardening plastic, followed by the fitting and fixing of the mouthguard to the stumps treated abutment teeth.

Filling mouthguard self-hardening plastic temporary prosthesis carry out at least two times, the first layer of plastics cold-curing thickness of 1.0 to 1.5 mm to compensate for loss of hard tissue, the second 0.5-1.0 mm to restore the pink aesthetics and fixing an artificial acrylic teeth.

Filling defects of the dentition using artificial acrylic teeth is done by creating between the artificial tooth and the tooth-antagonist clearance equal to the thickness of the mouthguard.

Fixing dental acrylic teeth and self-hardening plastic on the dentition of the patient carried out at the time of manufacture a permanent structure.

The novelty of the proposed method is to replace the gypsum model of the defects of the dentition using artificial acrylic teeth to their pre-fixation on the model in the field of defects, then after fabrication of mouthguards with fixation of artificial C is a scale by compression of the teeth mouthguards with drawing on the inner surface of the artificial acrylic teeth pink elastic plastic and fill the inner surface of the mouthguard in the area treated teeth hardening plastic carry out the fitting and fixing of the mouthguard to the stumps treated abutment teeth.

So, fill in the plaster model of the defects of the dentition using artificial acrylic teeth allows in combination with the fill-hardening plastics and Kappa create a durable and aesthetic design that allow you to replace the defects of dentition in the same plane and in different anatomical planes, as well as to stabilize the dental system, to prevent the development of dentoalveolar deformities and relapses after orthopedic or orthodontic movement of teeth in their normal position.

Signs: fill mouthguard self-hardening plastic in the area of the occlusal surfaces of the temporary prosthesis carried out at least twice, the first layer of plastics cold-curing thickness of 1.0 to 1.5 mm to compensate for loss of hard tissue, the second 0.5-1.0 mm to restore the pink aesthetics, filling defects of the dentition using artificial acrylic teeth is done by creating between the artificial tooth and the tooth-antagonist clearance equal to the thickness of the mouthguard, and fixing the mouthguard with acrylic teeth and self-hardening plastic on the dentition of the patient, carried out at the time of manufacture a permanent structure, are in what nakami, revealing the specific implementation of core topics, and is aimed at achieving the invention of the task.

Thus, the fixation of dental acrylic teeth and self-hardening plastic on the dentition of the patient, carried out at the time of manufacture a permanent design that allows you to keep chewing, phonetic function, and aesthetics of the patient's face.

According to a patent information search characteristics of the proposed method have the criteria of patentability - novelty, involve an inventive step and are industrially applicable.

The proposed method is as follows.

Originally from imaut alginate mass of impressions of the teeth of the upper and lower jaws. Next, print cast plaster model of the jaw. The area of the defects of the dentition complement artificial acrylic teeth with the selection of their color. When the defect is implemented by its replacement by drawing on the plaster model of self-hardening plastic on the anatomical shape of the tooth. Then the obtained model with fixed artificial teeth are made mouthguard of cellulose plastic method of thermoforming, whereby a working model is placed in a vacuum apparatus and squeezed it warmed celluloid plate. From the obtained plate cut mouthguard with coverage far from the problematic teeth. Then trim the mouthguard on gingival line of restored teeth. After preparation of the abutment teeth to produce the fit mouthguard with artificial teeth to the dentition of a patient with pre-made self-hardening plastic. After polymerization plastics excess removed by cutting with a cutter, and make relines mouthguards by layering (application) self-hardening elastic pink plastic on the inner surface of artificial teeth. The final operation is to fix the fabricated structures to the abutment teeth on temporary cement (for example, "Repin", SpofaDental, Czech Republic).

A specific example of using the proposed method.

P is roncallo for each individual patient are preparing the problematic tooth (teeth) in compliance with a number of standard rules i.e. the removal of plaque from all tooth surfaces with a brush and polishing paste, complete removal of carious tissue, to the sound of crepitate, removal of pigmented dentin, test using a caries-marker. Then listed below perform the required operations of the proposed method.

A patient (age 38) appealed with complaints about aesthetic defect, expressed in the absence of 1.5 and destruction 1.4 and 1.6. Physical examination asymmetry of the face is not found, the third face is proportional. From the anamnesis: 1.5 no more than 10 years, 1.4 and 1.6 were previously covered cast dental bridges with intermediate part 1.5. The mucosa in the region of 1.4, 1.5, without pathological changes. Stump 1.4 supplemented pin tumbler-stump tab.

Rastamaniak bridge prosthesis with support for 1.4 and 1.6 happened about two years ago. To the dentist is not addressed. The result was dentoalveolar moving 4.5 and 4.6. After holding the position correction 4.5 and 4.6 began to compensation defect 1.5 and restore anatomical form 1.4 and 1.6. Diagnosis: Partial secondary edentulous 1.5. Class III according to Kennedy. Etiological sign of caries and its complications.

In order to bridge the defect of dentition, normalize the function of chewing on the stabilization time of dentition pic is e move 4.5 and 4.6, the patient was asked to make a temporary fixed prosthesis retention based on 1.4 and 1.6 and the intermediate part 1.5. In the future it was planned to replace it by a bridge of metal-ceramic prosthesis based on 1.4 and 1.6 with the intermediate part 15 on the upper jaw.

During the first visit alginate dental impression mass "Hydrogum" (Zhermak, Italy) took an imprint of the upper and lower jaws. Then carried out the casting from plaster working and auxiliary models, the modeling of the composite anatomical forms 1.4, 1.6 teeth. No 1.5 compensated artificial acrylic teeth and anatomical 1.4 and 1.6 restored using composite material chemical polymerization "Evicrol" (SpofaDental, Czech Republic). Then the obtained model with fixed thereto an artificial tooth in the region of 1.5 and restored anatomical forms 1.4 and 1.6 have produced a Kappa of cellulose plastic method of thermoforming, whereby a working model was placed in a vacuum apparatus and pressed her heated celluloid plate. From the obtained plate was cut Kappa. Pruning was carried out according gingival line of restored teeth. From mouthguards removed the remains of the composite, washed.

During the second visit were treated abutment teeth for porcelain fused to metal crowns, took a two-layer duatepe prints silicon "Speedex" (Coltene, Switzerland). After processing has made the relocation of temporary crowns by making the inner surface of the mouthguard sa is overdouse plastic "Temp S" (Bisico Germany), matched in color to the natural teeth of the patient. After solidification cut cutter plastic excess and made his second relines mouthguards by layering (application) self-hardening elastic pink plastic "PattemResin LS" (GC, Japan) on the inner surface of artificial teeth. Further recorded design to the abutment teeth on temporary cement ("Repin", SpofaDental, Czech Republic).

In the third visit was extracted temporary crowns from the oral cavity, probasbly constant construction and fixed permanent structure on glass ionomers cement.

The use of the proposed method created a temporary prosthesis aesthetic appearance, was sturdy and easy to use. Further observation showed that recurrence of dentoalveolar deformities was not.

A second specific example of implementation of the proposed method. Initially the patient B. with damaged crown parts 3.4 and 3.5, a diagnosis of partial secondary edentulous 3.6, 3.7 II class at Kennedy, alginate mass took impressions of the teeth of the upper and lower jaws. Further prints were cast plaster model of the jaw. Anatomic shape 3.4 and 3.5 restored with composite material chemical polymerization. Then the resulting model produced a Kappa of cellulose plastic method thermoform the Finance. Next he produced a scrap of mouthguards on dental line of restored teeth 3.4 and 3.5. After recovery stump 3.5 pin tumbler-stump tab and preparation of the abutment teeth made the fit of the mouthguard to the dentition of a patient with pre-made self-hardening plastic material to "Temp S" (Bisico, Germany). After polymerization plastics excess removed by cutting with a cutter. Then made design fixed to the abutment teeth on temporary cement ("Repin", SpofaDental, Czech Republic).

The construction is made aesthetically pleasing fit and had high strength provided by the combination of bonded splints, artificial acrylic teeth and two layers of plastic.

Using the proposed method allowed us to store the geometry and aesthetics of the surface of the dentition. Staying in the Kappa-hardening plastic gave her the necessary rigidity, and Kappa gave the whole structure elasticity and played the role of the skeleton (framework). This feature has allowed to create temporary crowns on teeth that are located in different anatomical planes. Transparency and luster Kappa create the illusion gloss enamel, expanding indications for the use of such temporary crowns in the anterior. The elasticity of the mouthguard explains the possibility of its application without stress for the entire masticatory apparatus is in condition not fully stable dentition after tooth movement in orthodontic and orthopedic indications.

Currently, the authors have developed methodological recommendations on the use of the proposed method, experimental work on its implementation. Decided after conducting patent examination method essentially to proceed to its implementation.
