The most common oral problem faced by 90% of people is caries. He is treated with a filling. There are a lot of varieties of filling composite now. Consider the modern high-quality Japanese-made material "Estelight". These are light-curing filling materials used by dentists for filling and restoring the dentition. Due to the presence of a large number of shades, both posterior and anterior teeth can be filled.
What is a light filling and how is it different from a regular one?
Light filling refers to modern composites, which are made under the influence of a strong light source. This material contains a substance that is sensitive to light. Under the influence of ultraviolet radiation, it decomposes into radicals and thus occurs in the seal itself.polymerization process. Due to this, the shade that the filling material acquires for the teeth is quite similar to the color of the nearby dentition.
Unlike a conventional filling, the light material hardens under the influence of a polymerization lamp, and the dentist can more accurately fit it in shape. In addition, such a filling is more durable than a conventional one, and it is also easier to match the color to the dentition. To an outsider's eye, the light composite or reflector is invisible.
Estelight filling material: features and release form
Recently, dentists have been using materials from the Japanese company Estelight to restore or restore tooth enamel. They polymerize in just 10 seconds (one layer), while the composite retains softness and plasticity.
With the help of the material, you can mask through and volumetric defects, choose the appropriate shade, which over time will acquire the color of the dentition. Dentists note that it is very convenient to use the composite, because it does not stick to the instrument and keeps its shape well.
Estelight filling material is available in special 3.8 gram syringes and 0.2 g single doses, depending on shades.
Common Shades:
- BW - for pre-bleached teeth;
- WE - light-colored enamel;
- CE - transparent enamel;
- OA1-OA3 - opalescent shades that are used to restore the oralcavities of the 3rd and 4th grades.
You can also use shades as dentine, if you restore tooth enamel in several layers at once. The material is suitable for deciduous teeth, but is not suitable for metal dentures.
The composition of the composite contains 82% silicon and zirconium, due to which shrinkage is minimal, and strength and wear resistance are high. It is versatile and easy to use.
Application areas
Dentists actively use Estelite fillings to treat dental caries. The material is used both for the posterior (chewing) teeth and for restoring the aesthetics of the enamel on the front teeth. Thanks to a special composition developed by Japanese scientists, the composite is resistant to mechanical abrasion, and the surface shines.
Since such a filling material is universal, therefore it is used for both adults and children for the treatment of milk teeth. Also, the composite worked well on the dentition with veneers, when removing the diastema, restoring the occlusal surface and the opacity of the tooth. In total, there are more than two dozen shades of fillings. But they do not apply to the dentition, which has lost its color under the influence of tetracycline.
Working principle
Working with Estelight filling material is easy and simple, besides, filling is fast, dentists say. Thanks to the same depthdemineralization and penetration of adhesive substances, dentinal structures are filled simultaneously. The design as a whole turns out to be monolithic, without gaps, regardless of the structure of the surface of the tooth enamel.
An aesthetically attractive, high-quality and durable filling is placed in the minimum amount of time. At the same time, caries in this place no longer occurs, since the material releases fluorine ions.
How to use:
- The surface of the dentition is treated with a paste (without fluoride).
- The appropriate shade is selected (filling of bleached teeth can be carried out no earlier than two weeks after the manipulation).
- The tooth is isolated with a rubber dam and the cavity is sanitized.
- In order to avoid sharp drops from the restored area to the edge, the enamel of the posterior tooth is smoothed, and a bevel is made along the edge on the anterior dentition.
- To restore an artificial tooth (ceramic or composite), a diamond bur is used to increase adhesion and roughen the surface.
- Etching is done with phosphoric acid.
- Glass ionomer material or calcium hydroxide spacer provides pulp protection.
Benefits
The main advantages of using the Japanese material "Estelight" is its versatility and aesthetics. The brand's nanocomposite called Sigma Quick is suitable for the restoration and restoration of both posterior and anterior teeth.
Estelight Sigma Quick filling material has many advantages:
- used both to restore color and to give the correct shape to the anterior or lateral dentition;
- high wear resistance (tooth enamel is not erased or deformed with prolonged use);
- a large number of shades, which makes it possible to choose the most suitable for the dentition;
- has a “chameleon effect” (the filling acquires a tooth shade over time, this in turn minimizes material that is incorrectly matched in color);
- ease and speed of application;
- tooth surface is shiny and smooth.
But the Russian market also has Italian-made material "Estelight Asteria", which has similar qualities and advantages with the Japanese product. The only difference between these two filling materials is that "Asteria" has a somewhat limited range of colors, and is also applied to the tooth in two layers. Other characteristics, high quality, and also the price are almost the same.
How is the preparation and recovery going?
In order to choose the right shade of the nanocomposite "Estelight", there is a certain scale. But you need to pay attention not only to this. When in doubt, dentists prefer a lighter shade, because the comparison takes place on wet teeth, and they are known to be somewhat darker. You should start working with bleached teeth no earlier than 14 days after the procedure, as they tend to darken.
The material is applied to the cavity in layers of 2 ml each. Polymerization occurs after each applied layer. It is important to monitor the thickness and curing time. Finishing with a diamond bur and polishing with a rubber head.
Often the question arises when installing a light seal, after how much you can eat or drink liquid. Here the dentists were divided into two groups. The first one believes that you can eat and drink immediately after the manipulation, but you need to limit the intake of products with coloring pigments for the first two days.
Another group of dentists is sure that you should still refrain from eating or drinking for two hours after installing a light filling. They motivate this by the fact that after exposure to light irradiation, the place of the tooth where the filling is installed is sensitive for some time and has increased permeability. This may cause pain or change the shade. This is especially true for the restoration of the anterior teeth.
Important points
When using Estelight filling material, it is important to pay attention to the integrity of the package. Since the product is widely known in many countries, it is possible to purchase a fake that is significantly inferior in quality to the original.
Precautions when using Estelight nanocomposite:
- use only with medical gloves;
- if the material gets on the mucous membrane, eyes, respiratory organs or clothing, rinse immediatelysurface;
- use the composite only in accordance with the instructions;
- material is purchased only by professional dentists or licensed clinics;
- after using the filling material, all instruments are sterilized;
- polymerization by the device is carried out only in goggles.
Contraindications
In some people, the use of the material "Estelight" may cause allergic reactions to one or another component in the composition (most often to methacrylic monometers). In this case, you should stop using it and look for an analogue. There are no other contraindications to the use of the nanocomposite, which is why it is considered universal, since it is used even for treating the teeth of young children.
After filling, the oral cavity is thoroughly cleaned and washed with water to avoid getting the material into the mucous membrane or into the esophagus. Composite particles may cause irritation or other he alth problems.
Reviews
According to the reviews, the filling material "Estelight" is evaluated by the clients of dental clinics only positively. Its strength, high wear resistance, quality and aesthetically beautiful tooth after filling are noted. In addition, the risk of developing caries in this area is minimal.
Some customers noted that when installing a light seal with this material, it did not change either the shade or the quality even after several years. It is well tolerated even by children, since the procedure does not takea little time.
Conclusion
Both patients and dentists appreciated the high quality of the Estelight nanocomposite, both Japanese and Italian. This material is versatile and durable. Therefore, more and more modern clinics prefer this “new generation” composite, which can be used for the restoration and restoration of chewing and anterior teeth. And a large assortment of shades allows you to choose the most suitable material in color.
