SUBSTANCE: root canal of a broken tooth is filled up to a physiological opening under X-ray control. The root canal is milled at two-thirds of overall length in diameter equal to that of a fibre glass pin to be used in the tooth. A seat protrusion with a cylindrical side surface surrounding a root canal aperture is formed. The milled root canal and an outer surface of the root are imprinted in silicone to produce a model, wherein the fibre glass pin is mounted into the reflected root canal. Intraradicular and supraradicular root inlays are modelled in wax on top of the pin. Along the outline of the modelled inlay, a circular shoulder skewed at an angle of 45 degrees is milled, and the fibre glass pin is removed. The produced wax structure is scanned in a module of CAD/CAM system. The virtual image is transferred to a computer unit, followed by milling of a ceramic block. The produced structure is mounted in the oral cavity on glass-ionomer cement. An artificial crown is made and attached to the above structure.

SUBSTANCE: method of repairing a demountable dental prosthesis of the upper jaw consists in matching and fixation of fragments of the demountable dental prosthesis by glue, manufacturing a stone model by the fixed prosthesis, extension by a dental cutter of fracture borders and formation on external borders of retention cavities, parallel to the fracture line, in the quantity of three, on the entire length of the fracture line, equally distant from each other. The ratio of the area of the line, which passes on the fracture line, and the area of the retention cavities must correspond as one to three, while initially the area corresponds to the diameter of the cutter, selected individually by a value obtained as a result of division of the fracture line length by five. After the described preparation the prosthesis is washed, dried, placed on the model, and the formed in the process of milling slots are filled with plastic with the following polymerisation in boiling water under pressure. The obtained prosthesis is processed, ground, polished and fixed in the oral cavity.
EFFECT: restoration of durability and functional characteristics of the broken demountable dental prosthesis by the method affordable for the patient.
SUBSTANCE: in oral cavity of patient in prosthesis bed flexibility of mucous membrane is measured in oral cavity of patient in prosthesis. Borders of poorly flexible areas are determined. Before packing basic plastic paste on model in cuvette, on prosthesis bed borders of poorly flexible areas are outlined. They are extended for 1.5-2 mm in towards flexible areas. Durable insulating material with width not less than value of flexibility of mucous membrane is fastened on said extended boarders of poorly flexible areas. Cuvette with gypsum model is filled with paste of basic plastic and placed under the press. Plastic polymerisation is carried out. After polymerisation prosthesis is extracted from cuvette and processed.
EFFECT: method, due to preparing gypsum model of jaw before packaging basic plastic, makes it possible to reduce excessive pressure, trauma and atrophy of prosthesis bed tissues in the area of poorly flexible areas of prosthetic bed.
SUBSTANCE: computer analysis of the patient's speech material is performed. The frequency of sound is determined in the norm for a phoneme, selected from the group: "s", "ts" and "f", the frequency of the same sound for the patient before prosthetics, the frequency of the same sound after prosthetics. After prosthetics the phonetic rehabilitation index (FRI) is calculated by the mathematical formula. If FRI is larger than one, successful phonetic adaptation of the patient to dental prosthesis by the phoneme is determined.
EFFECT: method makes it possible to increase the accuracy of estimating the quality of performed dental intervention, and correction.

SUBSTANCE: odontopreparation is followed by impression taking. A dental model is injected into cast. Anatomic forms of retainer teeth is restored in wax, and an intermediate part of the prosthesis is modelled. The cast model is imprinted in silicone. The teeth are prepared. A reinforcing fibre tape is prepared. A segment of fibre tape impregnated with universal adhesive is placed on the teeth along the full length taking into account a profile of the masticatory surface up to an equator. The prepared segment is fixed on the teeth with the universal adhesive by polymerisation in halogen light. Self-hardening plastic is placed into the silicon impression to be inserted into the oral cavity.
