Composite materials for restorations
Performing direct artistic restoration requires the use of reliable, color-stable and durable materials that cannot be erased.
Due to their excellent characteristics, light-curing composite materials are used in dentistry. Photocomposites have excellent adhesion to dental tissue at the molecular level and do not change their position due to the ability to diffuse into enamel and dentin, and at the same time they do not violate the aesthetic perception of the tooth. These materials are applied in very thin layers to compensate for shrinkage due to photopolymerization. If the application technology is followed, a long-term, consistently high-quality effect is achieved.
To most accurately match the material to the mechanical characteristics of the tooth and its color (everyone’s teeth are individual), dentists layer materials of different shades and properties on top of each other. The result is a complete imitation of high-strength translucent enamel.
The strength of photocomposites allows them to be used in the restoration of anterior and chewing teeth that receive maximum load. Many of these materials contain fluoride ions, which helps prevent the development of secondary caries over the entire surface of the filling.
When restoring teeth of irregular shape, their visual contour is often corrected, the corners are smoothed or, on the contrary, sharpened, giving an individual uniqueness to the smile.
The advantage of direct restoration is that all the work will be done in one visit to the dentist (2-6 hours). Modern materials are suitable for closing gaps between teeth, changing their shape, size and color.

Every person sooner or later is faced with the need for dental treatment and prosthetics . He is sometimes faced with the very difficult question of choosing a method and design from the large number of options that modern dentistry offers. Of course, this choice must be made with the participation of a qualified specialist, but still the patient needs to get a clear idea of what the result will be in a particular case. Photos of teeth before and after the events help to do this in the best possible way.
This section presents the results of the work of our specialists, real cases from clinical practice: photos of the front teeth and their restoration, photos before and after orthodontic treatment , dental prosthetics and others.
They will help you better understand how effective a particular technique is. For example, by looking at a photo of the upper teeth before and after a person had veneers installed on his front teeth, you will be able to appreciate the excellent aesthetic effect achieved. with braces and aligners are amazing . And if you are going to have dental prosthetics, but you don’t know which prosthesis is best, look and choose the most suitable option and discuss the possibility of making it with your dentist.

Restoration of anterior teeth using composite filling materials –
In this chapter we will talk about how artistic restoration of the front teeth is carried out using specific examples - 1) in the first video you will see the replacement of an old, darkened restoration of a front tooth with a new one, 2) in the second video the restoration of an extensive chipped front tooth is shown. These videos perfectly demonstrate how artistic aesthetic dental restoration differs from conventional tooth filling.
For example, a special cast is used here to accurately restore the palatal surface of the tooth, as well as a layered restoration technique, which allows, by combining filling materials of different shades, to obtain an aesthetic result that is close to ideal (so that the restored part of the tooth does not differ in color and transparency from the natural tooth tissues). In fact, not all dentists have such skills, and there is no doubt that a certain artistic talent is needed.
Restoration of anterior teeth: video
The main stages of dental restoration:
- Preparation for restoration - at this stage it is necessary to hygienically clean the teeth from plaque and tartar, determine the color of the tooth being restored using a special scale and, in accordance with this, select the colors of the composite filling materials that will be used in the restoration process.
- Local anesthesia (if necessary)
- Drilling out tissues affected by caries - if an old unsatisfactory-looking restoration is being replaced, then the old filling is drilled out.
- Isolating a tooth from saliva - the use of cotton balls is almost universally a thing of history.
Their use does not allow reliably isolating the tooth from saliva, as well as from the patient’s wet breath, which also significantly worsens the quality and reliability of fillings and restorations made of composite filling materials. Now a rubber dam is used for this purpose. It is a latex scarf with holes for the teeth, which is pulled over the teeth. Composite dental restoration performed without reliable isolation from saliva and wet breath may not last long. Firstly, excessive moisture will cause a violation of the marginal seal of the filling to the tooth tissue, which can lead to the appearance of a dark strip or caries at the filling/tooth interface. Secondly, your restoration may simply fall out at one point, because... moisture impairs the adhesion of filling material to tooth tissue. - Fixing the pin in the canal - this stage is carried out if the crown of the tooth is destroyed by more than 1/2 and the tooth is pulpless. In this case, it is necessary to strengthen the filling by installing a pin, otherwise the restoration may fall out under load (24stoma.ru).
- Restoring the shape of a tooth with filling material – to make the tooth look natural, the layered restoration technique is used. In this case, layers of filling material of different shades and different transparency are applied to each other, which together then give the tooth a natural appearance. And this is real art.
- Finishing of the tooth – finishing should be understood as the final modeling of the tooth shape using burs, as well as grinding and polishing of the filling.
Indirect method of restoration of chewing teeth
The use of the indirect restoration method involves performing most procedures outside the patient's mouth. If the tooth is destroyed by more than 50%, then the installation of an inlay is required, which will make it possible to preserve the natural tissues of the destroyed tooth as much as possible. In addition, the tab will help eliminate the further development of caries and the need for pulp removal in the future. The use of ceramic inlays for the restoration of chewing teeth will restore not only the appearance of the tooth to its ideal condition, but also its functionality.
Artistic or aesthetic restoration of teeth
Each of us wants to feel beautiful and express emotions openly, and not by covering our mouth with our palm. Therefore, we “repair” chewing teeth only when they lose their functionality - but artistic restoration of the front teeth is often performed solely for aesthetic reasons, when treatment is not necessary.
This direction is also called aesthetic dental restoration or art dentistry. Its task is to form a beautiful smile zone.
Artistic or aesthetic restoration of anterior teeth
Using art dentistry methods, the following congenital and acquired deficiencies of the anterior row can be corrected:
- change in color of one or more teeth;
- incorrect location in the dentition;
- gap between teeth;
- chipped tooth;
- enamel defects;
- anatomically irregular shape and size of teeth.
Artistic dental restoration is always a search for a golden mean between a “Hollywood” and a natural smile. Therefore, a good dentist must be a bit of an artist and sculptor, able to find a balance of shape, transparency and colors.
A professional dentist always has a palette of special paints of 10-12 shades, which allows him to achieve maximum natural color for each patient.
Prevention at home
Preventive (precautionary) measures at home are as follows.
- Proper oral hygiene.
The use of fluoride-containing toothpastes, in which the amount of fluoride is at least 1100 ppm. Brushing your teeth with sufficient time and frequency (at least 3 minutes 2 times a day, and before bedtime is mandatory), using antiseptic and anti-caries elixirs and dental floss.
- Reducing the amount of sweet, sour and starchy foods in the diet.
Mandatory rinsing of the mouth after eating, and if this procedure is not possible, use chewing gum with xylitol (it has a pronounced anti-caries activity). It is also advisable to eat fresh fruit or vegetables after meals, because... they help clean the surface of the teeth from food debris.
- Brushing your teeth alone is not enough to prevent plaque buildup.
Therefore, it is recommended to visit the dentist once every 3-6 months for professional hygiene. Dental plaque is a place of active reproduction of cariogenic microbes, so its timely removal prevents the formation of foci of demineralization, and hence the development of caries.
Considering that caries is an infectious disease, in order to prevent infection of other teeth, it is necessary to promptly treat teeth already affected by caries.
Young children who are bottle-fed or given sweet water before bed are much more likely to have frontal dental caries. To avoid this, it is recommended to wipe your teeth after feeding with formula or breast milk, and before going to bed, give only plain water.
Ceramics on zirconium
Such metal-free crowns for the front teeth are an opportunity to combine strength, reliability, and aesthetics. Indistinguishable from natural teeth, do not cause allergic reactions, and can withstand severe loads.
But the price of such products is quite high, so they have not yet gained universal popularity.
Metal-ceramic crowns
Metal-ceramic crowns.
This type of prosthesis is a metal frame lined with ceramic mass and glaze on top. The more professional the technician, the more the crown is indistinguishable from a natural tooth. These crowns are strong, wear-resistant, have a long service life, and have been used by dentists for more than a hundred years. Advantages of metal-ceramic crowns:
- Withstand very strong chewing loads without deformation of the frame;
- The service life of metal-ceramics reaches 10 years or more;
- They have an aesthetic appearance and are visually indistinguishable from natural teeth (cases of specific lighting are not considered);
- Relatively low price.
Disadvantages of metal ceramics:
- Before installing crowns, the teeth must be sharpened sufficiently (up to 2 mm on each side), and because... the anterior teeth have a smaller volume compared to the chewing teeth, the percentage of prepared tooth tissue is quite high;
- In many cases, tooth depulpation is required, since during grinding the pulp often dies, this is revealed already when the crowns are installed and the entire complex of work must be repeated;
- After some period of time after installation, blue discoloration may appear along the edges of the crowns - the blue edge of the gums. This problem arises in connection with the metal base of the structure;
- When replacing one or a pair of teeth under certain lighting, there will ALWAYS be a noticeable difference between the natural teeth and the crown.
Crowns for the upper front teeth or crowns for the lower front teeth - which one to prefer?
My main rule of work as a podiatrist is to help you quickly achieve your perfect smile and protect your teeth. The frontal units are given special attention. This is a beauty zone
, a person’s sense of self, his general mood, and image component depend on its beauty.
Therefore, the dentist’s task is to make the crowns on the front teeth visually similar to the natural row. Technologies allow you to select materials from different price categories. Each option has advantages and some disadvantages.
Metal ceramics
Budget model made of a metal frame lined with ceramics.
Metal-ceramic crowns on the front teeth are able to withstand loads, allowing you to bite a hard apple without fear and not be sad. Subject to hygiene rules, they last for 10 years. By the way, not only the metal base makes it possible to install a bridge crown on the front teeth, but also zirconium dioxide structures made using CEREC technology... again in just 2 hours
, and the complexity of the bridge does not play a role in this case! .
A well-chosen shade brings the prosthesis closer to the natural color; only a specialist can distinguish them. Belong to an affordable price category.
Ceramics
Porcelain was first used as a tooth substitute almost 300 years ago by the Frenchman Fauchard, but the prototype of a modern denture has little in common with it. Modern ceramics offer endless possibilities when restoring the front row. Dentures are created specifically for installation on the front teeth, for single prosthetics and are not functional as part of bridge structures.
Sparkling elements indistinguishable from natural teeth:
- Attractive, does not change tone.
- Durable and reliable.
- They will make naturally crooked front teeth irresistible; crowns will repeat the anatomical structure of damaged teeth.
- They are characterized by increased biocompatibility.
There is one "but"
: the strength of crowns depends on the accuracy of their use. The main rule is minimal loads. Avoid biting into hard foods or using your teeth as a tool. Porcelain units do not allow such free handling.
Ceramics
– presentable crowns for the front teeth, but their price is higher than that of metal-containing analogues.
Emax crowns for front teeth made of reinforced glass ceramics are stable, but their cost is not yet affordable for everyone. By the way, in my clinic the cost of E-max crowns starts from 27,900 rubles per unit
. Quite affordable price with very high quality workmanship.
Zirconium
Zirconium crowns for front teeth are popular, despite the high price. They are similar in strength to metal and are functional. The solid composition strengthens the tissues of the damaged tooth, restores size and shape.
Advantages of zirconium dioxide crowns:
- Excellent biocompatibility, thermal conductivity.
- Inertia.
- No tendency to chip.
But there are also disadvantages - in addition to the significant cost, there is an aesthetic drawback - the lack of natural transparency, which can be seen upon close examination.
Direct aesthetic restoration of posterior teeth
It includes the following steps:
- Teeth cleaning, selection of composite material by color, pain relief.
- Removal of affected tissue.
- Isolation of the tooth from moisture.
- Installation of a pin into the root canal.
- Tooth extension.
If there is significant tooth decay, it is first necessary to identify the reasons that led to this, and then consider possible restoration methods.
Unfortunately, some dentists are inclined to remove a tooth that is more than half destroyed. But qualified specialists are still inclined to give the “native” tooth the opportunity to last as long as it can.
The causes of tooth decay are different:
- untreated caries;
- tooth injury;
- loss of filling;
- bruxism.
If you decide to save a tooth through restoration, then this must be done as quickly as possible so that the neighboring teeth are not destroyed. Dental restoration using a pin is considered the most reliable. Installation of a pin is indicated when there is almost no natural tissue left from the tooth. There are several types of pins:
- silver;
- fiberglass;
- anchor;
- titanium.
