Teeth serve a person for chewing food. If the jaw cannot perform this function, then you will have problems with the intestines, because coarsely ground food is poorly digested, it loads the stomach and liver too much. Naturally, there are various dental diseases of the oral cavity that lead to the loss of crowns. This situation needs to be corrected. Modern dentistry has a lot to offer. Prosthetics, prices for which range from $ 200 and above, will help solve all existing problems. In addition, user reviews of such designs are mostly positive.
A bridge is a special design that helps replace several missing teeth. Today it is very popular, as it has an acceptable cost and other positive qualities. Let us consider in more detail all the features of this design and the stages of its manufacture.
Why is prosthetics necessary?
Replacing lost teeth is a real salvation not only for those who have lost crowns due to trauma, but also for the elderly, whose he alth may deteriorate precisely because of the absence of somejaw parts. There are situations when a person loses one or more of their own dental crowns, for example, from a blow, injury or some kind of dental disease. In this case, they must be replaced so that not only the chewing function is preserved, but also the aesthetic appearance of the smile.
The bridge allows you to meet these requirements. In addition, it has a lot of advantages that make the design in demand. If the procedure for restoring the dentition is not carried out, then the person will not be able to eat normally. In this case, there are problems with the gastrointestinal tract and other body systems.
Advantages and disadvantages of designs
A bridge has many advantages:
- Possibility to restore the chewing function and the integrity of the dentition.
- Light weight.
- A large number of types of bridge structures, which allows you to choose the most suitable option in each individual case.
- Affordable value.
- Ease of maintenance.
- Possibility of replacing a damaged design.
- Restoring aesthetic norms.
- High comfort level while chewing and talking.
- Quick getting used to the design.
Of course, the bridge has some disadvantages. For example, it is necessary to wait some time until the structure is manufactured and installed. In addition, the service life depends on what materials were used for manufacturing. Fromthe cost of the prosthesis also depends on this.
Contraindications and indications for the installation of the structure
It should be noted that there are certain factors that allow the installation of such a dental prosthesis:
- Birth defects of the teeth.
- Loss of crowns due to trauma or certain dental pathologies.
- Unaesthetic appearance of a smile if the defect cannot be corrected by other methods.
Naturally, such a dental prosthesis also has contraindications for installation:
- Not too thorough oral hygiene.
- Incorrect bite that needs to be corrected by other methods.
- Bruxism, as well as a predisposition to rapid abrasion of natural crowns.
- Severe periodontal disease or other dental pathologies that have become acute.
- Osteoporosis (excessive friability of bone tissue).
- Inflammatory or infectious pathologies of the oral cavity.
Differences between crowns and bridges
There are different types of dentures. Naturally, the type you choose depends on many factors. However, there are several basic structures that are used in dentistry: bridges and crowns. They have certain differences between them.
Crowns and bridges differ in the number of elements, the way the structure is fixed in the dentition, and also in functionality. Considerthis question in more detail. For example, a crown is an artificial cap that fits over the entire part of one tooth above the gum. Various materials are used for the manufacture of these elements. In addition, they are not always installed in order to correct an aesthetic defect or chewing function. Sometimes a crown is mounted in order to be able to fix the structure to correct the bite or dentition.
The bridge, the photo of which you can see in the article, is a non-removable structure that is fixed on several of your own teeth. It is used exclusively to replace lost natural crowns. Such a prosthesis can be based on both its own and artificial teeth.
Varieties of prostheses
Before you start making a bridge, you need to figure out what types of structures are. So, they can be classified like this:
1. One-piece cast. Its feature is that it can be made in its pure form, with cladding and spraying. This design looks like a single whole. Solid bridges have certain advantages:
- Long service life.
- Low cost.
- Good resistance to abrasion, chipping.
- This bridge is very quick and easy to make.
- During the installation of such structures, the dental tissue is grinded quite a bit.
One-piece cast bridges also have disadvantages -metallic color. Therefore, they should be used to restore the part of the line that is behind the cheek and is not shown during a smile.
2. Metal-ceramic. This design is one-piece and is made of metal, however, porcelain lining is applied to its surface. Such prostheses are not as expensive as ceramic ones, and are not ideal in terms of aesthetics. Metal-ceramic bridges are in great demand and have good strength. The advantage of this design is that it is not erased and is not subject to caries. Even if part of the porcelain is chipped, it can be restored. However, metal-ceramic bridges have certain disadvantages. For example, teeth during installation have to grind very hard. In addition, such bridges are quite expensive, although they are affordable.
3. Ceramic. This prosthesis is the most expensive. However, it practically does not differ from natural crowns in appearance. These structures are not susceptible to corrosion, caries. These dentures sit tightly on the teeth, so they cannot accidentally come off.
4. On tabs. They are ceramic and metal. The most important advantage of this design is that the teeth on which it will be installed do not need to be completely turned. However, such a product is used only in case of loss of one crown and is less stable than the rest. If you want to get a bridge like this, it will cost between $150 and $500.
5. On implants. These prostheses are considered the most expensive. The fact is that they are mounted on implants specially implanted in the gums. It should be noted that such a construction can be disassembled. The minimum cost of such a product is $200.
6. Plastic. Most often, such products are used in order to protect the dentition, which has already undergone a processing procedure. This design is inexpensive.
7. Adhesive bridge prosthesis. Most often, fiberglass is used to make such a product. The design feature is that it is removable. It can be used to replace one tooth. Adhesive bridge is low cost.
If you want to carry out prosthetics, the types of prostheses presented in the article will help you decide what you need.
Features of fastening the structure: adhesive method
This method is considered more gentle. The fact is that for the installation of the product, it is not necessary to sharpen the natural crowns much. In addition, modern prostheses are made from special photo-curing materials. Moreover, you can restore the dentition in this way without using the services of a dental laboratory.
I must say that the procedure for manufacturing and installing the prosthesis takes only 3 hours. In this case, the supporting elements are non-removable devices that are installed on the supporting teeth. Special composite materials are used for fastening.
Preparation for the installation of the prosthesis
Before you start making a bridge, you should definitely prepare. For example, the patient must visit the dentist so that he can carefully examine his oral cavity. This is done in order to see the patient's problem and take measurements.
Of course, before installing the product, you will have to carefully monitor the he alth of the oral cavity. If you want to install fixed bridges, then all measurements must be taken carefully so that the design fits perfectly to your bite.
Please note that if you have any infections or inflammation of the teeth, then they must be cured before installing the prosthesis. Naturally, one must also take into account the condition of the jaw. If the patient has excessively loose bones, then the installation of the prosthesis is impossible.
What materials are used in the manufacture of structures?
If you are missing part of your jaw or if you have lost several crowns as a result of an injury, then you need prosthetics. You have already learned the types of prostheses. Now we should consider the question of what these products are made of.
First of all, it must be said that the structure is made of metal. The safest is the gold-platinum composition. Despite the fact that it is the most suitable for a person and does not cause allergic reactions, it is too expensive for the patient. Nickel alloy is cheaper and more affordable for the layman. It is considered easierprocessing, takes root well in the oral cavity. The only drawback of this composition is that it is not hypoallergenic.
Cob alt-chromium compounds are very often used. They have excellent biocompatibility. And they have high strength, so they can serve for a long time. Pure metal molybdenum crowns are extremely rare. However, it is added in small amounts to other formulations. Beryllium should not be used in the manufacture of bridges. The fact is that they have carcinogenic qualities, that is, they cause granuloma.
As for the outer coating, porcelain is already familiar here. Although it can chip, this material has excellent aesthetic properties, does not cause allergic reactions and can be used for a long time.
Features of manufacturing and installation of the bridge
Before you start the installation of the structure, you need to make it. And this requires not only time, but also the experience of specialists. The first step is the clinical phase. That is, a specialist determines the condition of the oral cavity and, if necessary, prescribes treatment for gums or teeth. Next, it is necessary to prepare those crowns that will serve as the basis for the bridge. That is, the teeth will need to be ground to the required size. After taking all the measurements, the data is sent to the laboratory, where the product is manufactured.
Steps in the manufacture of the bridge process suggest a certain sequence:
- Firstit is necessary to make a model of the jaw based on the data obtained. For this, wax is used. After the frame is prefabricated, it is cast from metal. Construction of the actual bridge begins.
- After the design is covered with a very thin layer of gold, which will ensure good compatibility of the product with biological tissues. In addition, it helps to hide the dark tone of the metal.
- After that, a layer of ceramic should be applied. However, this procedure is repeated several times. In this case, one should take into account the shade of teeth that is inherent in a person by nature. Only in this case, natural crowns will not differ from artificial ones.
- During the construction of the bridge, the patient will have to visit the dentist several times to try it on.
It is worth noting that some designs do not require strong turning of the teeth. Small notches should be made on them, to which prostheses are glued. During the manufacturing process, a temporary protective prosthesis can be placed on the processed crowns. It will help protect the crowns and speed up getting used to the future prosthesis.
After the construction is completed, the bridge is fitted and fitted. In this case, the dentist must check whether the bite is disturbed, whether the teeth are well closed. If necessary, you have to slightly adjust the prosthesis. If everything is in order, then you can proceed with the installation of the product. This procedure does not take long. It is advisable to carry out the installation process with an experienced doctor, after which you will not have to redo the work.
After installation, you must carefully monitorprosthesis. If your element breaks off or the top coating is chipped, you must definitely contact the doctor who installed the structure. He must correct the defect. If you do not pay attention to the problem, then the bridge may completely deteriorate, and then you will have to pay much more for the manufacture of a new product.
These steps for making a bridge are essential.
How to properly care for dentures?
Now it's time to figure out whether to take care of the prostheses. First of all, you should learn: despite the fact that artificial teeth are practically resistant to corrosion and caries, they still require some care so that you can extend the life of the structure.
First of all, please note that after installing it, you still need to get used to it. To do this, you should not load the prosthesis too quickly according to the “full program”. Otherwise, you may feel discomfort or even pain. If this feeling persists, then the design is not put on correctly and the defect should be corrected. To do this, contact the doctor who performed the installation. You may need to adjust the bridge further.
Next, be sure to follow good oral hygiene. That is, brush your teeth twice a day, use rinses and floss. In this case, the surface of the artificial enamel will be clean and beautiful. In this case, the prosthesis will be able to perform its functions for a long time.
If your design has changed color, then get a hygienic cleaning at the dentist orteeth whitening. If there are problems with the abutment crowns, then it may be necessary to replace or reinstall the bridge.
That's all the features of the use and installation of the prosthesis. Stay he althy!
