The invention relates to medicine, namely to the field of dentistry.

Included defects in patients with partial primary and secondary edentulous occur in orthodontic patients often enough, according to some authors, this figure reaches 20% (1). On the stages of the orthodontic treatment of various types of braces patients included defects with partial primary and secondary edentulous addressed the issue of creating and maintaining a place in the dentition. The lack of tooth in front is a significant aesthetic problem for most patients.

In the treatment of patients with the included defects with partial primary and secondary edentulous known method of orthodontic treatment using braces without defect closure. In this case, at all stages of treatment of the edentulous area remains open, which in turn requires no additional material costs (2).

The disadvantage of this method is the reduced quality of life caused by the violation of the aesthetics of the smile, the difficulty in pronunciation hissing sounds, patients Shepeleva", splash saliva through a defect during a call, patients reduced sociability may be formed of psychological complex of self-doubt.

There is a method of closure included defects of the part is but removable laminar dentures (3).

The disadvantages of this method for patients is a bulky device, because in the process of treatment, the size of the replaced defective constantly changing and fixing partly removable laminar denture is deteriorating. Patients experience discomfort when eating, fear about the loss of the denture from the mouth, which leads to reduced quality of life. If the patient is partially removable laminar denture for the doctor increases the number of visits associated with the relocation of the prosthesis.

There is also known a method of closing included defects in the dentition by using a standard artificial plastic teeth. Plastic tooth is determined by the size of the defect from the set of standard teeth, it is soldered to the bracket and the whole structure is fixed to the arc ligature wire for braces.(4)

The disadvantage of this design is that during operation of the artificial tooth is closely adapted to the gum and it quickly formed a bed sore. Under the action of chewing load an artificial tooth plays in the arc, damaging the soft tissue. An artificial tooth is difficult to find an ideal fit for the size of the defect and the color palette of the patient's teeth.

This method is used for the prototype.

The aim of the invention is to develop a way to close the party included defects in the dentition, to improve the quality of life of patients with enabled defects with partial primary and secondary edentulous during orthodontic treatment.

This goal is achieved by the fact that the closure of defect occurs in stages:

prepare two glass tubes with a diameter of 1 mm, the length corresponding to the size of the defect; fiberglass tube is placed ligature wire with a diameter of 0.250 mm; fiberglass tube cross in the center of the defect and ligature wire with one hand engages the node so that it turned out "eight"; the free ends of the ligature wire is fixed to the abutment teeth braces; fiberglass tube impregnated with an adhesive system of the fifth generation, are polymerized led lamp, on fiberglass pipes made of composite material is made of individual artificial teeth.

The method is accompanied by graphical material. The figure 1 shows two fiberglass tubes placed in them ligature wire that intersects and is fastened in the form of "eight"; the figure 2 diagram of the fixing fiberglass tubes with ligature wire for braces supporting teeth; figure 3 - scheme of production of individual artificial teeth, on fiberglass pipes, fixed for the Breck is s abutment teeth built ligature wire.

On the graphic material shown:

1 - fiberglass tube with a diameter of 1 mm, the length corresponding to the size of the defect;

2 - ligature wire with a diameter of 0.250 mm;

3 - abutment teeth;

4 - bracket;

5 - custom made artificial tooth.

The method is as follows.

The patient at the stage of orthodontic treatment using braces removed casts silicone mass. Before removing the braces and casts arc were insulated white protective orthodontics.com wax, except for the braces on the abutment teeth. After receiving copies of their quality assessment are cast model plaster. The abutment teeth are moulded from super plasters 3 class. The supporting teeth are the teeth, limiting defect in the dentition. The model is covered with an insulating varnish.

Prepare two glass tubes with a diameter of 1 mm, the length corresponding to the size of the defect. In the fiber-optic tube is placed ligature wire with a diameter of 0.250 mm Fiberglass tube cross in the center of the defect and ligature wire with one hand engages the node so that it turned out "eight". The free ends of the ligature wire is fixed to the abutment teeth braces. Fiberglass tube impregnated with an adhesive system of the fifth generation, polymeris who are led lamp. On the fiberglass tubes of composite material is made of individual artificial teeth.

Tailor-made artificial tooth corresponds in shape, size and color of the patient's teeth. With the help of the positioner depending on group membership tooth on tailor-made artificial tooth is fixed bracket on the flowable fotokompozitsionnogo material. Polishing is carried out with design.

In the oral cavity of a patient design prepassivate, is fixed to the abutment teeth braces integrated ligature wire through the bracket, depending on its design. If you are using ligiously bracket, the design is tied to an arc short ligature wire. If you are using self-ligating bracket, the arc is placed in the bracket slot and closes the cover bracket.

The technical effect of the invention is to improve the quality of life of the patient due to double fixation tailor-made artificial tooth using the built-ligature wire and bracket system, improves the aesthetics of a smile at the expense of defect closure tailor-made artificial tooth, the lack of fit design to the mucous membrane of the mouth during long wearing eliminates the trauma of the oral mucosa RT and facilitates the conduct of oral hygiene.

CLINICAL EXAMPLES

Example 1. Patient S., 25 years old, came to the clinic complaining of aesthetic disadvantage, diastema and Treme between the teeth. The difficulty in pronunciation hissing sounds. The patient experiences a lack of self-confidence when communicating with others. After the necessary diagnostic tests, the patient was diagnosed Natroalunite. Partial primary edentulous lateral incisors of the upper jaw. Included defects in the upper jaw. The patient was fitted with self-ligating braces, the Damon system 3. At the stage of orthodontic treatment in the process of creating space for the missing lateral incisors, defects in the dentition were closed using standard plastic teeth fixed on them braces. This design has been committed to an arc using the lock bracket. The patient was satisfied with the aesthetics. After a week of using this design, the patient began to experience pain in the area of fixed artificial teeth. The patient experienced discomfort while wearing this design, when biting food artificial tooth is moved on the arc and hurt the gums. The patient had experienced difficulties when performing oral hygiene, a tight fit of the artificial tooth to the gum prevented qualitative plaque removal and OS is Atkov food.

Objective: artificial teeth closely adjacent to the gum. Gums hyperemic, edematous, in place fit the artificial tooth to the gum identified erosion.

To improve the quality of life of the patient, we have produced individual artificial teeth with double locking system.

Closure of the defect occurs in stages: prepare two glass tubes with a diameter of 1 mm, the length corresponding to the size of the defect; fiberglass tube is placed ligature wire with a diameter of 0.250 mm; fiberglass tube cross in the center of the defect and ligature wire with one hand engages the node so that it turned out "eight"; the free ends of the ligature wire is fixed to the abutment teeth braces; fiberglass tube impregnated with an adhesive system of the fifth generation, are polymerized led lamp, on fiberglass pipes made of composite material is made of individual artificial teeth. With the help of the positioner on tailor-made artificial tooth is fixed bracket on the flowable fotokompozitsionnogo material. Polishing is carried out with design. In the oral cavity of a patient design prepassivate, is fixed to the abutment teeth braces integrated ligature wire and using the lock bracket.

P is ciento noted the improved quality of life, beginning more confident smile. This design is easy to use, the patient did not experience pain and discomfort, convenient holding of oral hygiene. When eating design is tightly fixed and does not move in an arc, which eliminates the trauma of the soft tissues of the oral cavity. This design is not adapted tightly to the gum and previously existing erosion quickly epithelials. The patient reported an improvement of diction and self-esteem. The patient continued to wear tailor-made artificial tooth after the implantation.

Example 2. Patient D., 20 years old, came to the clinic with complaints on the aesthetic disadvantage of anterior teeth, displacement of the middle line to the left and subulate right lateral incisor of the upper jaw. After the necessary diagnostic tests, the patient was diagnosed Natroalunite. Partial primary edentulous lateral incisors of the upper jaw on the left. The defect in the upper jaw. The displacement of the middle line on the upper jaw to the left. Subulate right lateral incisor. The patient had been installed ligature braces system Inspire ICE. At the stage of orthodontic treatment in the process of creating space for a missing lateral incisor on the left of the defect in the dentition was closed with the help of partial removable laminar denture. First the initial the patient was satisfied with this design, but after a month of wearing the distance between the teeth is increased and partial removable laminar denture began to subside. From that moment she began to constantly worry, fearing that the prosthesis may fall from the mouth.

To improve the quality of life of the patient, we have made individual artificial teeth with double locking system. Closure of the defect occurs in stages: prepare two glass tubes with a diameter of 1 mm, the length corresponding to the size of the defect; fiberglass tube is placed ligature wire with a diameter of 0.250 mm; fiberglass tube cross in the center of the defect and ligature wire with one hand engages the node so that it turned out "eight"; the free ends of the ligature wire is fixed to the abutment teeth braces; fiberglass tube impregnated with an adhesive system of the fifth generation, are polymerized led lamp, on fiberglass pipes made of composite material is made of individual artificial teeth. With the help of the positioner on tailor-made artificial tooth is fixed bracket on the flowable fotokompozitsionnogo material. Polishing is carried out with design. In the oral cavity of a patient design prepassivate, is fixed to the brackets supporting ubov integrated ligature wire and using a ligature wire for braces.

The patient reported an improved quality of life, her smile became more confident. This design is easy to use, well fixed in the oral cavity, the patient did not experience pain and discomfort. The patient reported an improvement of diction and self-esteem. When eating design is tightly fixed and does not move in an arc, which eliminates the trauma of the soft tissues of the mouth and loss of structures of the oral cavity. The patient continued to wear tailor-made artificial tooth after the implantation.

During orthodontic treatment significantly decreased the quality of life of patients. This is due to the wearing of orthodontic appliances, the pain and difficulties when performing oral hygiene. Reduction of self-esteem is celebrated in most orthodontic patients, but greater feelings experienced by patients with defects of dentition in the anterior. Closure included defect in the anterior stage of the treatment, first of all, improves the aesthetics of the smile and diction, and consequently, improves the quality of life of the orthodontic patient during treatment. Secondly, tailor-made artificial tooth with double locking system reduces the risk of injury to the mucous membranes of the oral cavity. It is also possible to binyavanga application opens spring with this design and fixation distances by increasing the width of the tailor-made artificial tooth addition of a composite material on approximal the surface of the artificial tooth. The use of tailor-made artificial tooth after surgery implantation exclude injury in the affected areas during the entire period of osseointegration of the implant.

The method is intended for closure included defects in the frontal section at stages of treatment of patients with partial primary and secondary edentulous braces and can be used in orthodontics and prosthodontics.

SUBSTANCE: invention relates to dentistry and is intended for application in orthopedic and therapeutic dentistry. Gypsum models of patient's jaws are made. Biomechanics of lower patient's jaw movements is studied. Angles of sagittal and transversal joint paths of patient are determined. Obtained values are marked on scale of joint units of articulator, which imitates individual movements of patient's lower jaw. Gypsum models are placed in claimed apparatus and ceramic thin half-crowns are modelled on them under constant control of interaction of dentitions and articulation contacts, proper to patient. Preparation of teeth before application of prosthesis according to method includes grounding off sharp enamel crests and processing teeth surface by airbrasive machine with powder with size 50 mcm under pressure 20 atm until dull surface of enamel appears.

EFFECT: method makes it possible to reduce trauma and preserve viability of teeth with prosthetic appliance due to elimination of preparation of hard tissues of said teeth.

SUBSTANCE: invention refers to medicine, namely to dentistry and may be used in the orthopaedic treatment of the patients with partial and/or complete denture defects using removable laminar dentures. A method involves making the removable laminar dentures, taking the oral hygienic measures, cleaning the removable laminar dentures. Ozonised olive oil is applied on an internal surface of the prosthetic basis that is followed by applying the prosthesis on the denture defect for 10-30 minutes. The prosthesis with ozonised olive oil applied on the internal surface of the basis is attached once a day for 8-16 days.

EFFECT: method provides more effective patient's adaptation to the removable laminar dentures due to the polycomponent mechanism of ozonised olive oil in the same environment with no negative side effects.

SUBSTANCE: invention refers to medicine, namely dentistry, and aims at the prosthetic dentistry quality assessment. High-viscosity elastomer 0.5-0.6 cm3 that is a basic layer A of Silagum Putty silicone is divided into two equal portions and placed on occlusal surfaces of the patient's fifth and sixth lower prosthetic teeth on the right and left. The patient is asked to occlude the teeth for 3-4 seconds. The test result is considered to be positive if the prosthesis keeps on the lower alveolar process once the mouth is opened. If the prosthesis is retained by the material at the upper teeth, the test result is considered to be negative.

EFFECT: method enables obtaining the objecting data of the complete denture attachment to prosthetic bed due to the visual assessment of the test result.

SUBSTANCE: method involves producing an opening of diameter reaching 2 mm with diamond or hard alloy bore in adhesive cover after preparing abutment tooth and prosthesis or widening already available perforation also to diameter of 2 mm. The prosthesis is set on the abutment tooth and place is marked for creating and directing pin-canal in the area of cutting one-third of the frontal abutment tooth or in the lateral abutment tooth equator area. The pin-canal direction is to correspond to path for introducing the prosthesis. The pin is screwed-in with screwdriver and holder to a depth of about 2 mm into dentin. The prosthesis is set on the abutment for making control. The pin is filed-off to adhesive cover layer after having fixed the prosthesis on composition cement.

EFFECT: prolonged service life; high functional value.
