Metal-ceramic teeth. Prosthetic dentistry: cermets

Metal-ceramic teeth are very popular today. The fact is that they have an acceptable cost and a beautiful appearance, so they can hardly be distinguished from their own. In addition, they have other advantages. Naturally, before deciding on this type of prosthetics, it is necessary to understand all the subtleties of the manufacture and use of the product.

Advantages and disadvantages of crowns

Among the advantages can be identified as follows:

• The possibility of correcting the most complex flaws in the dentition.
• Crowns have a completely natural appearance.
• On such designs, the plaque appears less and tartar is formed.
• Crowns do not cause discomfort or allergies (it all depends on the reaction of the body to the metal used).
• Metal-ceramic teeth are characterized by durability.

Naturally, such designs have certain drawbacks. Some materials that cover the metal, can be broken (porcelain). Own teeth have a property strongly wear out, since artificial crowns are too hard. And the natural enamel has to be strongly worn to put on the crown.

In which cases can not be used similar constructions?

I must say that the metal-ceramic teeth can not always be put. Among the contraindications to the use of these crowns can be identified as follows:

• Weakness of our own teeth, which can not withstand additional stress.
• Too young (under 16 years).
• Malocclusion.
• Some chronic or inflammatory diseases.

Whether it is necessary to install metal-ceramic teeth, a specialist should advise after a thorough examination of the oral cavity.

Choice of fabrication material

Before you install the design, it is necessary to pay attention to the metal from which the crown base will be made. You can choose a simple alloy, which is much cheaper in value, or a combination of precious metals (platinum and gold, for example).

The price of the material is not the most important, though very important criterion for choosing a design. Some patients may show allergy to certain components of the alloy, so use them carefully. For example, people with high sensitivity should not use nickel or chromium.

As for gold, it never causes allergies, almost does not liquefy oxidation (so you will not suffer from bad breath or taste). As for ceramic coating, then most often used porcelain, although it must be carefully taken care of.

Varieties of structures

Metal-ceramic teeth are an alternative for those people who could not keep their own crowns. It is necessary to distinguish such types of structures:

1. With a shoulder mass. This type of crowns involves reducing the amount of metal and increasing the mass of the ceramic. The presented design has a very high strength.
2. Milled metal-ceramic crowns on the teeth. They almost completely correspond to the natural form of the jaw and bite of the patient.
3. Stamped. This type of construction is the cheapest and least durable.

If you need dental prosthetics, cermets are the best, but you should choose the type of product that is appropriate in your case.

Features of the construction

The technology of production of such crowns provides for a certain sequence of work. If you decide to do prosthetic teeth, cermets are not made in a day. So, experts should do all the work in stages.

1. Impression of the dentition. To do this, it should be covered with a special mixture.
2. Manufacturing of gypsum model. Cermet teeth, photos of which you can see in the article, can not be made without preliminary measures.
3. Modeling of the metal frame with the help of wax.
4. Making a crown of the chosen alloy and the first fitting the product.
5. Applying several layers of porcelain to the metal and firing the crown at high temperature.
6. Application of enamel on ceramics and the next fitting of the product.
7. If the crown is well suited to the patient, then its surface is glazed, polished and finally baked.

Naturally, this process requires high technological skill, patience and expertise. Therefore, all measurements should be taken carefully and carefully, so as not to spoil the raw materials. Try to order such prostheses in well-known clinics with a good reputation.

Features of maintenance of the structure

Despite the fact that the most popular product for prosthetics is cermet, teeth (reviews speak about durability and excellent operation of products) require some care. It is not complicated. For example, you will need to brush your teeth twice a day, as before, and use a conditioner with antibacterial properties. Very carefully it is necessary to concern to that place in which the gum or gingiva adjoins to metal.

Every six months, do not forget to visit a dentist who will monitor the condition of the crowns and natural tissues. Periodically, the surface of the teeth will need to remove plaque from tea and coffee, as well as from tobacco (if you smoke).

If a chip appears on the crown or you feel that it is staggering, do not try to remove it yourself. It is better to consult a specialist. He can do everything as accurately and painlessly as possible. Try not to crack such nuts with crowns, as porcelain has the property of cracking.

In any case, the most safe and practical material in prosthetics is cermet. Teeth, reviews about which are mostly positive, will last for a very long time, it is only right to take care of them. In addition, you will get a real aesthetic pleasure when you look at your smile in the mirror. Be healthy!
