The most common oral problem that 90% of people experience is caries. It is treated with a seal. There are a lot of varieties of filling composite now. Consider the modern high-quality material made in Japan by Estelight. These are light-curing filling materials that are used by dentists for filling and restoration of the dentition. Due to the presence of a large number of shades, both chewing teeth and front teeth can be filled.
What is a light seal and how does it differ from ordinary?
Light filling refers to modern composites that 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 the polymerization process takes place in the seal itself. Due to this, the shade, which acquires dental filling material, is quite similar to the color of the adjacent dentition.
Unlike ordinary fillings, light material hardens under the influence of a polymerization lamp, and the dentist can more precisely adjust it in shape. In addition, such a seal is more durable than conventional, and is also easier to match in color to the dentition. For prying eyes, the light composite or retroreflector is invisible.
Estelight Filling Material: Features and Release Form
Recently, dentists use materials from the Japanese company Estelight to restore or restore tooth enamel. Their polymerization occurs in just 10 seconds (one layer), while the composite retains softness and ductility.
Using the material, you can mask through and volume defects, choose the appropriate shade, which will eventually become the color of the dentition. Dentists note that it is very convenient to use the composite, since it does not stick to the instrument and holds its shape well.
Estelight filling material is available in special 3.8 gram syringes and 0.2 g single doses, depending on the shade.
Common shades:
- BW - for pre-bleached dentition;
- WE - light enamel;
- CE - transparent enamel;
- OA1-OA3 - opalescent shades that are used to restore the oral cavity of the 3rd and 4th classes.
You can also use shades as dentins, if you restore tooth enamel in several layers at once. The material is suitable for primary teeth, but is not used on metal prostheses.
The composition of the composite contains 82% of silicon and zirconium, due to which the shrinkage is minimal, and the strength and durability are high. It is a versatile and easy to use material.
Fields of application
Dentists actively use Estelite fillings to treat tooth decay. The material is used both for the lateral (chewing) teeth and for restoring the aesthetics of enamel on the front teeth. Thanks to a special composition developed by Japanese scientists, the composite is resistant to mechanical abrasion and the surface glistens.
Since such a filling material is universal, therefore it is used by both adults and children for the treatment of milk teeth. The composite on the dentition with veneers also worked well, while eliminating diastema, restoring the occlusal surface and the opacity of the tooth. Total shades of fillings more than two dozen. But they are not used on the dentition, which has lost its color under the influence of tetracycline.
Principle of operation
It’s easy and simple to work with Estelight filling material, and filling is quick, dentists say. Due to the same depth of demineralization and penetration of adhesive substances, the dentinal structures are filled simultaneously. The design as a whole is monolithic, without cracks, regardless of the structure of the surface of the tooth enamel.
For a minimum amount of time, an aesthetically attractive, high-quality and durable seal is placed. In this case, caries in this place no longer occurs, since the material emits fluoride ions.
Mode of application:
- The surface of the dentition is treated with paste (without fluoride).
- The appropriate shade is selected (fillings for whitened teeth can be performed no earlier than two weeks after the manipulation).
- The tooth is isolated with cofferdam, and cavity reorganization is performed.
- In order to avoid sharp changes from the restored area to the edge, the enamel of the lateral tooth is smoothed out and a bevel is performed on the front dentition along the edge.
- To restore an artificial tooth (ceramic or composite), diamond boron is used to increase adhesion and roughen the surface.
- Pickling occurs with phosphoric acid.
- Glass ionomer material or a gasket based on calcium hydroxide creates pulp protection.
Benefits
The main advantages of using the Japanese Estelight material are its versatility and aesthetics. The brand's nanocomposite called Sigma Quick is suitable for restoration and restoration of both chewing teeth and the front row.
Material for Estelight Sigma Quick fillings has many advantages:
- it is used both to restore color and to give the front or side dentition the right shape;
- high wear resistance (tooth enamel does not wear off and does not deform with prolonged use);
- a large number of shades, which makes it possible to choose the most suitable for the dentition;
- it has a “chameleon effect" (a filling acquires a tooth shade over time, this in turn minimizes material that is incorrectly selected in color);
- simplicity and speed of application;
- the surface of the tooth is shiny and smooth.
But on the Russian market there is also presented Italian-made material Estelle Asteria, which has similar qualities and advantages with a 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, as well as their price are almost the same.
How is the preparation and recovery going?
In order to choose the right shade of the Estelight nanocomposite, there is a certain scale. But you need to pay attention not only to this. If in doubt, dentists prefer a lighter shade, because the comparison takes place on wet teeth, and they, as you know, are somewhat darker. It is worth starting to work with whitened 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 takes place 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, dentists were divided into two groups. The first one believes that you can eat and drink right 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 food or water for two hours after installing a light seal. They motivate this by the fact that after exposure to light, the place of the tooth where the seal is installed is sensitive for some time and has increased permeability. This can cause pain or discoloration. This is especially true for restoration of the teeth of the front row.
Important points
When using Estelight filling material, it is important to pay attention to the integrity of the packaging. Since the product is widely known in many countries, it is likely to purchase a fake, which in quality is significantly inferior to the original.
Precautions when using the Estelight nanocomposite:
- use only with medical gloves;
- if material enters the mucous membrane, eyes, respiratory system or clothing, immediately rinse the surface;
- use the composite only in accordance with the instructions;
- the material is purchased only by professional dentists or clinics that have the appropriate license;
- after using filling material, all instruments are sterilized;
- polymerization by the device is carried out only in goggles.
Contraindications
For some people, the use of the Estelight material can cause allergic reactions to one or another component in the composition (most often to methacrylic monometers). In this case, it is worth stopping its use and finding an analogue. There are no other contraindications to the use of the nanocomposite, which is why it is considered universal, since it is even used to treat the teeth of young children.
After filling, the oral cavity is thoroughly cleaned and washed with water to prevent material from entering the mucous membrane or esophagus. Particles of the composite may cause irritation or other health problems.
Reviews
According to reviews, Estelight filling material is evaluated by customers of dental clinics only positively. Its strength, high wear resistance, quality and aesthetically beautiful tooth after filling are noted. In addition, the risk of caries in this area is minimal.
Some customers noted that when installing the light seal with this material, it did not change either the shade or quality, even after several years. It is well tolerated even by children, since the procedure does not take a little time.
Output
Both patients and dentists appreciated the high quality of Estelight nanocomposite, both Japanese and Italian. This material is versatile and wear resistant. Therefore, more and more modern clinics give preference to this particular “new generation” composite, which can be used for restoration and restoration of chewing and anterior teeth. A wide range of shades allows you to choose the most suitable material for the color.
