Cermet teeth todayare very popular. The fact is that they have an acceptable cost and 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 imperative to understand all the intricacies of manufacturing and using the product.
Advantages and disadvantages of crowns
Among the advantages are the following:
- The possibility of correcting the most difficult defects of the dentition.
- Crowns have a completely natural appearance.
- On such structures, plaque appears to a lesser extent and tartar is formed.
- Crowns do not cause discomfort or allergies (it all depends on the body's response to the metal used).
- Metal-ceramic teeth are characterized by durability.
Naturally, such designs have andcertain disadvantages. Some materials that cover the metal may break off (porcelain). Own teeth tend to wear heavily, as artificial crowns are too hard. And natural enamel has to be ground very hard to put on a crown.
In what cases it is impossible to use similar constructions?
I must say that metal-ceramic teeth can not always be put. Among the contraindications to the use of these crowns can be identified as follows:
- The weakness of their own teeth, which can not withstand the additional load.
- Too young age (up to 16 years).
- Malocclusion.
- Some chronic or inflammatory diseases.
Should I install cermet teeth, should advise a specialist after a thorough examination of the oral cavity.
Choice of fabrication material
Before you install the structure,Be sure 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 cost, or a compound of precious metals (platinum and gold, for example).
The price of the material is not the most important, althoughvery important criterion for the choice of design. Some patients may be allergic to certain components of the alloy, so they should be used very carefully. For example, people with high sensitivity should not use nickel or chromium.
As for gold, it never causesallergies, almost not susceptible to oxidation (so you will not suffer from bad breath or taste). As for the ceramic coating, then there is often used porcelain, although it must be carefully looked after.
Varieties of structures
Metal-ceramic teeth are an alternative for those people who could not save their own crowns. The following types of structures should be highlighted:
- With shoulder mass. This type of crowns provides for a decrease in the amount of metal and an increase in the mass of ceramics. The presented design has a very high strength.
- Milled metal-ceramic crowns on the teeth. They almost completely meet the natural shape of the jaw and bite of the patient.
- Stamped. This type of construction is the cheapest and least durable.
If you need dental prosthetics, metal ceramics would be the best fit, but you should choose the appropriate type of product in your case.
Features of the construction
The production technology of such crownsprovides for a specific sequence of work. If you decide to make dental prosthetics, cermet is not made in one day. So, experts should do all the work in stages.
- Impression of the dentition. To do this, it should be covered with a special mixture.
- Making a plaster model. Ceramic-metal teeth, the photos of which you can see in the article, cannot be made without preliminary fittings.
- Modeling metal frame with wax.
- Making the crown of the selected alloy and the first fitting of the product.
- Applying several layers of porcelain to metal and firing the crown at high temperature.
- Applying enamel on ceramics and another fitting products.
- If the crown is well suited to the patient, then its surface is glazed, polished and finally baked.
Naturally, this process requires hightechnological prowess, patience and expertise. Therefore, all measurements must be taken carefully and very carefully so as not to spoil the source materials. Try to order such dentures in reputable clinics with a good reputation.
Features design care
Несмотря на то что самым популярным изделием для prosthetics is considered metal-ceramic, teeth (reviews say about durability and excellent use of products) require some care. It is not complicated. For example, you just as before, you will need to brush your teeth twice a day, use a rinse with antibacterial properties. Very carefully it is necessary to treat the place in which the gum is in contact with the metal.
Do not forget to visit the dentist every six monthswhich will monitor the condition of crowns and natural tissue. Periodically from the surface of the teeth will need to remove plaque from tea and coffee, as well as tobacco (if you smoke).
Если на коронке появился скол или вы чувствуете, that she is reeling, you should not try to take it off yourself. It is better to consult a specialist. He will be able to do everything as accurately and painlessly as possible. Try not to crack nuts with such crowns, as porcelain tends to crack.
In any case, the safest and most practical.The material in prosthetics is metal ceramics. Teeth, reviews of which are mostly positive, will last for a very long time, you only need to properly care for them. In addition, you will get a real aesthetic pleasure when you look at your smile in the mirror. Be healthy!
