The invention relates to medicine, aesthetic dentistry, to remedy diastema with the use of reinforcing wire mesh.

Diastema is a space between the Central incisors (2).

The level of technology

From publicly available sources of information at the priority date of the application it is known that to eliminate diastema apply orthodontic treatment with the use of removable plates with springs, vestibular arches, levers or fixed devices Angle, crowns levers, hooks, springs, rubber traction) orthodontic treatment (3). For fixed devices for the treatment of symmetric diastema, otosaka devices such as orthodontic rings, vertical, tube, wire alloy with the properties of shape memory effect (5). The disadvantages of these methods are the duration of the treatment, high susceptibility to caries, violations of aesthetics during treatment.

Also known orthopedic remedy diastema using artificial crowns (3). The disadvantage of this method is substantial preparation of hard tissue of teeth, the presence of the edge gap, which accelerates the destruction prepariruetsya teeth, poor control over the formation of defects of hard tissues under the denture, difficult correction and repair design, high abrasion eats the state of the teeth-antagonists.

In clinical practice, the use of auxiliary treatment method diastema - surgical, which promotes self-regulation diastema and facilitate orthodontic treatment (4).

Closest to the technical essence is taken as a prototype, the method of reconstruction of the dentition with the use of composite material (1).

The main disadvantages of this method are:

1) low mechanical strength of the reconstruction;

2) frequent chipped and split.

The problem to which the invention is directed, is to develop solution diastema with the use of composite material and a reinforcing metallic and non-metallic (synthetic) permeable or porous metal plates (end-to-end porosity), ensuring elimination of the above disadvantages.

The technical result is the elimination of the diastema with the use of composite materials and metallic and non-metallic grids, without resorting to the use of orthopedic and orthodontic method of eliminating diastema (leaving these backup methods).

Advantages of the proposed invention are:

1) the reinforcing element is fixed taking into account the anatomic-topographic structure and the contour of the tooth crowns;

2) mesh - connecting mechanical link not only between the composite m is a material and hard tissues of the tooth, but by the portions of the composite material that provides structural strength and eliminates chipped and split;

3) metal mesh helps to reduce shrinkage of the composite material, resulting in improved marginal seal of composite to the tooth tissues;

4) increase the service life of the structure;

5) high aesthetic quality.

The technical result is the elimination of the diastema is achieved with regard to anatomical form, function and appearance of the reconstructed teeth, with the use of composite material and a reinforcing metallic and non-metallic grids, by placing the formed l-shaped grooves of the teeth, previously conducted retraction of gum, on the medial surfaces of the Central incisors create vertical grooves and cutting edges create horizontal grooves, vertical and horizontal grooves are connected to each other and thus form an l-shaped grooves, and then reinforcing grids mechanically attach G-shaped and set in the formed l-shaped grooves so that they stress was included in the formed grooves, after fitting a reinforcing mesh is removed, cover with adhesive, lightly blow air for uniform distribution and conservation through acestei will polimerizuet standard method, then put vtoro the layer of adhesive and repeat manipulation, next, grooves are subjected to acid etching, rinse thoroughly with water, dried, adhesive is applied twice and will polimerizuet, then the slots fill flowable composite and simultaneously set them reinforcing mesh and conduct directed polymerization, then diastema eliminate with the use of composite materials for anterior teeth, the aesthetic effect is achieved after processing standard polishing disks of different thickness and grain size of the abrasive. Approximally surfaces of the strips Correction of the cutting edges are under the control of occlusal paper finish using burs, disks.

The invention

Diastema is eliminated with regard to anatomical form and function and appearance of the reconstructed teeth.

Mechanically clean the surface of the Central teeth toothbrushes using toothpastes that do not contain fluorine. Determine the right color of the crowns on the standard scale VITA.

The dal are insulated from the liquid environment of the oral cavity with the help of the cofferdam.

After gingival retraction on the medial surfaces of the Central incisors create vertical grooves and cutting edges create horizontal grooves with regard to anatomical features of the pulp. Vertical and horizontal grooves connect with the battle and thus form an l-shaped grooves.

Depending on the clinical situation (if necessary) as a reinforcing element in the elimination of diastema use a grid of metallic and non-metallic (synthetic: polypropylene, fiberglass, ceramic, or porous permeable metal plate (end-to-end porosity: porous titanium, nickelide titanium), or a grid in combination of metallic and non-metallic materials.

Reinforcing grids mechanically attach G-shaped and set in the formed l-shaped grooves so that they are without voltage included in the formed grooves, thus cutting the surface of the mesh should not reach the cutting edges of the Central incisors on average 1.5 to 1 mm to ensure transparency of the cutting edges. After fitting the reinforcing mesh is removed, cover with adhesive, lightly blow air for uniform distribution and conservation through acestei will polimerizuet standard method. Then put the second layer of adhesive and repeat manipulation.

The grooves are subjected to acid etching, rinse thoroughly with water, dried, adhesive is applied twice and will polimerizuet standard method. The slots fill flowable composite, simultaneously set them reinforcing mesh and conduct directed polymerization vestibular, oral, and then cut the her surface (as setprimarykey composite material shrinks in the direction of the directional light). The method of the directed polymerization can reduce polymerization shrinkage, improve the regional seal. Next, diastema eliminate with the use of composite materials for anterior teeth, layers causing opaque and enamel layers of the composite. Conduct directed polymerization. The aesthetic effect is achieved after processing standard polishing disks of different thickness and grain size of the abrasive. Approximally surfaces of the strips. Correction of the cutting edges are under the control of occlusal paper finish using burs, disks. Produce final adviceline with palatal and vestibular surfaces, remove the cofferdam. Thus, this method allows to eliminate diastema, to increase durability design along with high aesthetics.

Clinical example.

Patient 24 years. Complaint: on the aesthetic dissatisfaction. Objective: the gap between 1.1 and 2.1.

Diagnosis: diastema Central incisors of the upper jaw.

Treatment: mechanically clean the surface of the Central teeth toothbrushes using toothpastes that do not contain fluoride.

Determine the right color of the crowns on the common scale is e VITA.

On the medial surfaces of the Central incisors form vertical grooves and cutting edges form horizontal grooves, the grooves are interconnected and formed l-shaped grooves.

For the manufacture of a reinforcing part of the proposed design uses a grid of metal that is designed for reinforcing basic dentures.

Reinforcing metal mesh mechanically attach the l-shaped form and set formed l-shaped grooves. After fitting the reinforcing mesh is removed, cover the adhesive and conduct polymerization.

After acid etching of the l-shaped grooves acid wash water when the saliva ejector. Next, dry the grooves, causing the adhesive and conduct polymerization. The slots fill flowable composite, simultaneously set them in a reinforcing metal mesh and conduct directed polymerization vestibular, oral, and then cutting surfaces. Next, diastema eliminate with the use of composite materials for anterior teeth, layers causing opaque and enamel layers of the composite. Conduct directed polymerization. The aesthetic effect is achieved after processing standard polishing discs razlichaetsya and grit abrasive. Approximally surfaces of the strips. Correction of the cutting edges are under the control of occlusal paper finish using burs, disks.

Produce final adviceline with palatal and vestibular surfaces, remove the cofferdam. Complication after carrying out the above method was not found.
