Filling material Estelite – high aesthetic results in two steps

8397

Those years when a visit to the dentist and the procedure for filling an affected tooth were the subject of physical and moral torment are far in the past.

Now, thanks to innovative scientific developments, high-quality and safe materials and modern equipment, monitoring the health of the oral cavity and promptly eliminating problems that arise has become comfortable and harmless.

This article will discuss the currently best filling material Estelite.

General overview

Estelite Sigma Quick is a modern composite mass, specially developed by Japanese specialists in the field of dental practice for filling teeth.

The drug is a universal set of elements characterized by radiopaque characteristics and excellent light-curing properties.

Combined with a high aesthetic factor and fast polymerization processes, the material has proven itself in clinics around the world, being one of the best products among its product range.

Areas of application

Dentists actively use Estelite fillings to treat dental caries. The material is used both for 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 shines.

Since this filling material is universal, it is used for both adults and children to treat baby teeth. The composite has also proven itself well on the dentition with veneers, in eliminating diastema, restoring the occlusal surface and opacity of the tooth. There are more than two dozen shades of fillings. But they are not used on teeth that have lost their color under the influence of tetracycline.

Composition and properties

A high-quality result and a high strength index are ensured due to excellent mechanical and physical characteristics due to the presence of all the constituent elements of the composite.

More than 80% of it consists of silicon-zirconium mass, which ensures minimal shrinkage of the material subsequently .

Choosing the right shade is quite easy - the product line includes about two dozen color options. The composition is perfectly polished, and the high-quality result lasts for a long period of time.

The mass is resistant to abrasion and has the highest wear resistance class.

How does it work?

Tooth fragments are filled with the composition at once, which ensures a uniform depth of penetration of the components into the cavity being filled and good adhesion.

The monomer completely fills the space, thereby creating a holistic composition. Such a filling will have reliable adhesion, regardless of the initial situation. The doctor’s task is to accurately calculate the filling boundary; for this purpose, a temporary color pigment is provided.

Main advantages of the product:

minimizing tooth enamel sensitivity and permeability;
versatility;
convenience.

Principle of operation

During the use of the material, dentin fragments are filled with the drug simultaneously, which allows achieving the same depth of internal penetration of adhesives and demineralization of the composition. The monomer forms a single structure through its 100% filling .

Regardless of the quality of the working area - dry, wet, or having undergone a preliminary preparation procedure, the adhesion force will be equally reliable.

The doctor is obliged to calculate the filling boundary as accurately as possible - a colored pigment will help him with this, which will subsequently disappear from the surface of the tooth on its own.

An important characteristic of the drug , which distinguishes it from analogue options, is a decrease in enamel sensitivity and a decrease in permeability.

Main advantages of Estelite:

versatility of use;
simplicity and ease of use.

Estelite – a new word in dental fillings

Quite a few patients will confirm that going to the dentist has always been a very difficult process and few could decide to do it voluntarily.
But the days when filling teeth was a painful procedure are long gone. Today, with the help of introduced innovations, new scientific approaches, high-quality materials and equipment, the prevention and treatment of the oral cavity will be painless and comfortable.

In this article we will talk about the material for filling teeth Estelite.

general information

Japanese scientists have created a special composite solution designed for affected teeth called Estelite Sigma Quick

. This is a special set of elements that have radiopaque properties and can be cured using light radiation.

In addition, this substance looks very aesthetically pleasing and does not stand out at the filling site. The polymerization process is quite fast, so the created product has become popular and used by many dental clinics around the world. Today it is included in the list of the best products among this kind of products.

Components and characteristics

The high level of quality and strength of the presented material is based on the excellent mechanical and physical properties that are inherent in the elements of the composition of this composite mass.

If we talk about filling, then Estelite largely consists of silicon-zirconium and composite filler. Its share in the total mass reaches 82%. The filling material also contains an inorganic compound, which is a spherical submicron filler. Its average particle size reaches only 0.2 microns, and the fractional composition fluctuates at the level of 0.1-0.3 microns. This element is responsible for the level of gloss and slow abrasion of the substance. The monomer base contains bis-glycedimethyl methacrylate (Bis-GMA) and triethylene glycol dimethacrylate.

The higher the degree of filling of the composite substance, the lower the level of polymerization shrinkage.

A feature of the Estelite filling material will be the use of RAP technology or a radical-enhanced polymerization activation system.

Using light radiation emitted by a photopolymerizer (peak wavelength is 470 nm), the time required for the substance to harden is reduced by almost three times compared to other materials traditionally used for filling teeth.

It is thanks to the presence of this unique system in the composition of the Estelite Sigma Quick material that the long service life of the filling is ensured. The substance is presented in syringes and in unit doses (PLT, “PreLoadedTip”).

How it works?

Dentin fragments are instantly filled with the presented preparation. This must be done so that the adhesives penetrate inside at the same level and to demineralize the composition. Only 100% occupancy allows the formation of an integral monomer structure.

In addition, the drug does not depend on whether the working area is dry or wet. The monomer adheres well and holds firmly, which is another positive quality of Estelite.

In order to calculate the material filling boundary with maximum accuracy, a special pigment is used. After the procedure, it easily disappears from the teeth and leaves no traces.

It is also worth paying attention to the fact that this drug significantly reduces the level of enamel sensitivity and promotes good strength. This is what allows it to be one level above traditional composite filling materials. Estelite is also distinguished by its versatility and ease of use.

Indications and contraindications

Due to the almost complete versatility of the product, the range of indications for its use is quite wide.

The drug can be used in most clinical situations, in particular:

for direct restoration of the frontal zone of the jaw row , for example, for small anterior cavities
when eliminating minor surface defects caused by mechanical damage - cracks, chips;
as a base layer when performing direct restoration;
for the treatment of organs by indirect restoration;
to eliminate external defects of other previously applied composite materials;
restoration of artificial row fragments;
elimination of gaps and diastemas of varying degrees of severity;
in the process of forming composite veneers - when applying the thinnest multi-layer overlays;
therapy of caries manifestations of all types.

Since the component contains methacrylic monomers, the main contraindication to the use of the mass is individual intolerance to this element, as well as a tendency to develop allergies to methacrylics and similar compounds.

Estelite Sigma Quick shades

A1, A2, A3, A3.5, A4, A5, B1, B2, B3, B4, C1, C2, C3, OA1, OA2, OA3, OPA2, BW (Bleach White), WE (White Enamel , white enamel) and CE (Clear Enamel/Incisal, transparent enamel/incisal shade).
Opalescent shades (OA1, OA2, OA3) have adequate degree of opacity necessary to block the darkness of the oral cavity (restoration of class III and IV cavities)

Opalescent shades can also be used as dentin shades for layer-by-layer multi-shade restorations. The shades OA1, OA2 and BW are well suited for the restoration of primary teeth. However, they are not intended for use as camouflage agents for metal teeth or highly discolored teeth such as tetracycline teeth.

OPA2 is intended for use as a camouflage agent for the treatment of minor stains, as well as for the restoration of opaque teeth (applied in a thin layer to the lingual wall of a Class III and IV cavity).

Rules for tooth preparation

Preparing the organ for the upcoming manipulation is an important process of therapy in general. Like the main stages of restoration, it is carried out strictly in accordance with the protocol and includes the following sequential actions of the doctor:

cleaning the enamel - the surface of the jaw row is carefully but thoroughly cleaned with a special rubber container with a mass that does not contain fluoride components. After treatment, the working area is washed with water;
tone selection – carried out using a shade scale. For the most accurate result, the selection time is a few minutes, since wet teeth are darker, and dry teeth, on the contrary, are lighter.
The main principle of selection is color saturation; from the most suitable options, the specialist will choose the most intense.
Important! Professional whitening cannot be performed before the procedure. In this case, there is a high risk of tone discrepancy, since some time after bleaching the organs will become darker and the discrepancy will be noticeable;
insulation – the best option is rubber dam;
preparation - manipulation is carried out according to the standard procedure, after which the surface is washed with water. When treating the frontal zone, bevels are made along the marginal part of the enamel, and in the lateral zone, the edges are somewhat smoothed. This will improve retention and aesthetic perception;
pulp protection - if the working cavity and the pulp are located nearby, a gasket is applied, which serves as a barrier protecting the delicate pulp tissue.
It is made from glass ionomer or calcium hydroxide. The use of eugenol and its derivatives as protection is not recommended, since the material impairs the polymerization process of Estelite;
application of adhesive - single-component mixtures with this filling composition are shown. However, they should not be self-curing, since the material will not provide the necessary adhesion effect.

Advantages

The main advantages of using the Japanese Estelite material are its versatility and aesthetics. The brand’s nanocomposite called “Sigma Quick” is suitable for the restoration and restoration of both chewing teeth and the anterior row.

The filling material “Estelight Sigma Quick” has many advantages:

used both to restore color and to give the correct shape to the front or lateral dentition;
high wear resistance (tooth enamel does not wear off or deform during prolonged use);
a large number of shades, which makes it possible to choose the most suitable one for the dentition;
has a “chameleon effect” (the filling acquires the shade of the tooth over time, this in turn minimizes the incorrectly selected material);
simplicity and speed of application;
the surface of the tooth is shiny and smooth.

But the Russian market also offers Italian-made material “Estelight Asteria”, which has similar qualities and advantages to 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. The remaining characteristics, high quality, and also the price are almost the same.

Stages of restoration

Unidoses should be used only within the instructions for use of the composition.

An ounce is measured in the dispenser, then the protective cap is removed. The paste is squeezed directly into the working cavity or preliminarily brought to the required consistency on a tablet.

If a syringe is used, the operating principle is as follows:

remove the cap;
turn the handle clockwise;
squeeze the required amount of component onto the tablet;
knead the paste.

After the material is ready for use, filling and restoration contouring begin . The paste is introduced into the hole in layers, not exceeding the maximum permissible depth in one application. The manufacturer offers a special table for this.

During the filling process, mixing Estelite with other pastes is unacceptable; this is fraught with the formation of voids and poor-quality polymerization.

Each layer must be polymerized separately - the time stated by the manufacturer. The device is located at a distance of about 2 mm from the working area.

The final stage is finishing. The restoration area is cleaned and polished using fine-grained diamond burs.

To make the boundaries between the filling and the tooth look as natural as possible, the doctor performs fractional grinding with a multifaceted carbide bur. No water is used, and the rotation speed of the bur is minimal.

The proximal parts are treated with special thin strips of vinyl or medical metal alloy.

The finished surface is polished with rubber nozzles or special devices designed for this.

Indications for use, preparation and application

The universal characteristics of high-quality fillings formed using Estelite provide a wide range of possibilities for use. Possible clinical indications include:

restoration of the frontal jaw area;
correction of surface defects on enamel;
direct restoration of the base layer;
restoration of installed prostheses;
elimination of gap-like spaces and diastemas;
therapeutic prevention of caries.

The presence of methacrylic-based monomers in the composition of the drug is a key factor limiting the possibility of use for people suffering from allergic reactions to compounds of this group. Intolerance to this element should be clarified before starting therapy.

When preparing the oral cavity for medical restoration, a number of procedures are performed in the required sequence:

Cleaning the enamel layer using a special mass that does not contain fluoride;
Selecting a color tone using a shade scale;
Isolation of the dentition element using latex plates;
Standard preparation followed by rinsing with water;
Pulp protection with an artificial glass ionomer barrier;
Application of the composition and formation of the restoration contour.

During the restoration process using Estelite, it is recommended to strictly follow the instructions for use. The composition is applied either directly into the working cavity of the tooth, or squeezed out of a syringe onto a separate tablet to give the desired consistency. The introduction into the hole is carried out layer by layer, without exceeding the depth, and each layer must undergo a polymerization procedure, the duration of which is determined by the manufacturer’s special table. It is important to note that mixing the composition with other restorative pastes leads to the formation of voids and defects in the final polymerization.

At the final stage, the finished filling is processed and polished using a fine-grained drill. To improve the aesthetic perception and appearance, fractional grinding technology is used at minimum speed, without the use of water. Proximal elements should be treated with vinyl or metal strips. The finished shape can be further polished using a special rubber nozzle or other device.

Precautionary measures

When working with the material, you must comply with the safety requirements stated by the manufacturer. In particular:

do not use the component for other purposes;
the product has a target orientation and is recommended for sale only to medical institutions and individuals who are practicing dentists;
It is better to refuse to use the product if there is even the slightest doubt about its authenticity, for example, the seal of the packaging is broken, or there are no special seals;
at the first signs of individual intolerance, work must be stopped immediately;
methacrylic monomers are classified as allergens, so the composition should only be used with protective gloves. You should be aware that the material has the ability to penetrate latex; at the end of the procedure, your hands should be rinsed well with running water;
do not allow direct contact of the drug with the skin, and if there is the slightest contact with the body or eyes, rinse the affected area and contact a specialized specialist;
After the session, the patient is recommended to rinse the mouth generously;
it is contraindicated to inhale Estelite vapors or swallow its contents - this can lead to irreversible health consequences;
at the end of the manipulation, all instruments that had direct contact with the filling mass are treated with alcohol;
During work, the specialist must wear safety glasses.
