The invention relates to dentistry, and in particular to methods of prosthetics patients with partial loss of the front teeth bridges.

The prior art method prosthesis with partial loss of teeth on the patent of Russian Federation №2146505 by preparation of the abutment teeth and attach a prosthesis. A distinctive feature of this method is that the inside of the prosthesis is fixed thread extending from approximal sides and the envelope abutment teeth in the form of loops, the free ends of which pass through tunnels formed by oral prosthesis surface. The thread is placed in the grooves previously formed on the perimeter surface of the abutment teeth, tightly covers the abutment teeth and closes with a filling material.

There is also known a method of restoring the dentition by the RF patent №2160568 (seems to be the closest to the claimed invention). When implementing the known method is used bridge girder design, the middle of which is fixed inside an artificial tooth, and the speakers on both sides of the ends are designed for mounting on the abutment teeth adhesive material. Beam design is simultaneously supporting frame for an artificial tooth and a means for attachment of the prosthesis in the cavity, formed the Anna on the level of fixation of the supporting elements of the prosthesis in each of the abutment teeth.

As follows from the practice of prosthetics, the use of bridges is shown in connection with their good functional properties. With the help of matovina dentures is the full restoration of chewing function, they keep well established occlusal relationships. These properties are provided appropriate orientation and fixation of the bridge relative to the restored dentition.

In the known method for these purposes provide additional orientation of the upper surface of the beam structure parallel to the approximal plane working surfaces of the abutment teeth, additional alignment levels and ensuring the parallelism of the supporting elements in accordance with the level and orientation of sites cavities formed in the respective abutment teeth, additional fitting and the fitting of adhesive bridges, as well as a preliminary adjustment of the bite.

Unlike well-known in the claimed way to replace a missing front tooth functional quality reinforcing mesh-adhesive bridge is provided by a different method.

The formation of the adhesive of the bridge and its correction with respect to the tooth row is carried out directly in the mouth in accordance with the level of the s, anatomical shape, size and orientation of the abutment teeth and the teeth of the antagonists.

Unlike traditional girder bridges used in the known method, the bridge used in the claimed method, is basically a new design of beams. It is made from a rectangular gilt metal mesh used in dentistry. The grid size is chosen from the condition that its length is not less than the sum of the lengths of the supporting elements designed to lock in the grooves of the abutment teeth and the length of the supporting part is designed to form an artificial tooth crown with composite materials. The supporting elements are arranged three on each side of the grid and executed in the form of a number of twisted between the wires of the grid. The ratio of the thickness of the supporting elements of the grid and groove depth required for fixation, provides gentle preparation of the abutment teeth during the formation of this groove.

The formation and selection of the number of support elements of the beams used in the proposed method, as well as additional reinforcement of the artificial crown by a grid structure supporting part increase the rigidity of the bridge (one of the main technical requirements for prosthetics dentures) and, consequently, increases strength is rotazione in General.

To solve the same tasks directed the use of polypropylene mesh. It is fixed in the vertical grooves made on the opposite approximal surfaces of the abutment teeth. Due to the use of polypropylene mesh reinforced artificial crown from the vestibular surface. This increases the strength of the replaced tooth and restored dentition, precise orientation, replaced front of the tooth relative to the dentition of the patient, taking into account individual peculiarities of this series.

Given the possibility of adjustments to the prosthesis directly in the process of replacing a front tooth, and design features of the bridge, the use of the claimed method replacement front tooth as shown in the case of selection of abutment teeth within groups bearing one function, and within the groups of teeth with different function. In addition, by fastening the abutment teeth by reinforcing plated metal mesh and polypropylene mesh application of the inventive method shown in the case of the mobility of the abutment teeth with the provision of the claimed technical result.

When replacing a front tooth of particular importance for the patient acquires the aesthetics of prosthetics. Use in the claimed method of reinforcing etok, the shape of which matches the shape of the oral and vestibular surfaces of the coronal part of the replaced tooth, allows to form the crown in accordance with its anatomical characteristics, and anatomical features of the tooth row.

Typically, the prosthesis included defects of the anterior dentition using permanent dentures appropriate after 5-6 months after removal of the front teeth, as soon as the alveolar ridge. Otherwise, due to the atrophy of the alveolar crest between the body of the prosthesis and a crest, you may receive the slit and, as a consequence, the speech. The application of the inventive method shown in this case. The specified defect can be eliminated by the restoration of the coronal part of the replaced tooth composite materials without violating the integrity of the prosthesis.

Technical result achieved during the implementation of the claimed invention is to improve durability, reliability and aesthetics of the restoration of the dentition with minimal injuries of the abutment teeth, as well as in the reduction stages of the replacement of a missing anterior tooth by eliminating used in traditional methods of prosthetics bridges laboratory stages of their manufacture and adjustment.

<> The invention

Mechanically surfaces of the teeth adjacent the defect, clean toothbrushes using a polishing pastes, and determine a suitable color according to the standard scale VITA.

On the abutment teeth from oral surfaces form three horizontal groove to a depth not exceeding the thickness of the enamel. The grooves are used to hold the support elements (upper, middle and lower) grid-adhesive bridges.

On the other approximal surfaces of each of the abutment teeth form vertical slots for fixation of polypropylene mesh. The vertical depth of the grooves is also within the thickness of the enamel.

Thus, each of the abutment teeth formed three thin horizontal groove of the oral surface and one vertical on approximal surfaces.

Next are forming a grid-adhesive bridges directly in the mouth. To do this, take gold plated metal grid, the height of which no more than the height of the coronal part of the replaced tooth, and the length not less than the sum of the lengths of the supporting elements designed to lock in the grooves of the abutment teeth and the length of the supporting part that follows the contour of the oral surface of the replaced tooth and is designed to form artificially the crowns with composite materials. On both sides of the longitudinal grid wires are released from the cross at a distance equal to the length of the supporting elements, divided into three parts on each side and twisted together. The thickness of the supporting elements of the grid provides a gentle method of preparation of the abutment teeth.

Thus, from a grid form the skeleton of the bridge, consisting of three supporting elements moving in the carrier portion, consisting of gold-plated metal mesh, formed in accordance with the contour of the oral surfaces of the missing tooth.

In order to give rigidity of the formed bridge prosthesis from the vestibular surfaces of the missing tooth, place an additional reinforcing element of polypropylene mesh. Width polypropylene mesh should be 1-2 mm greater than the width of the missing coronal tooth structure, and height not exceeding the height of the crown part. After the installation of polypropylene mesh in the pre-formed vertical grooves grid acquires a concave shape to fit the shape of the vestibular surfaces of the missing tooth. The concavity formed by the grid due to the set-difference grid size and the missing coronal tooth structure.

Thus perform a double reinforcement of a coronal part of the replaced tooth: from the oral surface is STI - gold plated metal mesh, and from the vestibular surface of the polypropylene mesh. After fitting and correction of reinforcing elements hold the acid etching of the abutment teeth. Acid wash running water while running the saliva ejector, air dried and applied the adhesive, lightly blow air to evenly distribute, perform a standard polymerization method according to the instructions. After spending the fixation of the flexible support elements gold plated metal mesh and polypropylene mesh with cement in the respective grooves of the abutment teeth.

Then the metal and polypropylene mesh mechanically connected by means of thin metal filaments, forming a combined grid frame, consisting of gold-plated metal and polypropylene mesh. Then proceed to the final restoration of the missing front tooth in accordance with its anatomical shape and anatomical features of the restored dentition.

Of mechanically strong (microfilaraemia) composite material from the oral surface form of artificial enamel layer in accordance with the anatomical shape of the tooth. This metal mesh is located in the environment of the composite artificial enamel layer and form on Traut oral surface of the tooth crown.

The space formed between oral formed artificial enamel layer and a polypropylene mesh, fill microfilament composite, forming artificial dentin.

From microfilaraemia composite form of artificial enamel layer from the side of the vestibular surface of the crown part, with concave polypropylene mesh is located in the environment of the composite artificial enamel layer and form repeats the vestibular surface of the tooth crown.

Restored declared by way of a coronal part of the tooth consists of artificial enamel layer, reinforced with oral surface of the metal mesh, and on the vestibular surface of the polypropylene mesh, between which is located an artificial antinomy layer of microfilaraemia composite material.

To achieve the aesthetic effect of process and grinding restored tooth standard polishing disks of different thickness and grain size of the abrasive and diamond forests.

Occlusive editing is performed under the control of the occlusal paper, finish using burs, disks.

Restoration of the claimed way to replace the missing tooth with the use of reinforced grid-adhesive bridges of metal and polypropylene PP is lenovos grids allows to increase the strength and durability of the missing tooth along with providing high aesthetics.

The way to replace a missing front tooth with the use of reinforcing mesh-adhesive bridges, including the formation of three horizontal and vertical grooves, respectively, by oral and approximal surfaces of each of the abutment teeth, the formation of the skeleton of the bridge from a rectangular gilt metal mesh, fixed in a horizontal slots through three supporting elements made of longitudinal wires of the grid, the pre-formed on its opposite sides, and polypropylene mesh fixed in the vertical grooves and additionally sealed with a metal grid of thin metal filaments and the consequent formation of the composite materials of the tooth crown in accordance with its anatomical shape, reinforced gold plated metal mesh and polypropylene mesh respectively with oral and vestibular surfaces.
