According to statistics, even the fillings of the highest quality is unlikely to last you more than five years. At the end of life they lose their aesthetic appearance due to staining. And the area of contact between the seal and the dental tissue may develop secondary caries.
That’s why in modern dentistry there is an alternative treatment option – the use of dental tabs. What are their advantages we will cover in this article.
The seal is formed by the doctor from a special material directly into the oral cavity of the patient, then it hardens and is polished to give the correct shape. Even with a precision of a therapist then take some time to get used to the seal.
THAN A DENTAL ONLAY IS DIFFERENT FROM FILLINGS
Tab household dental technicians in the laboratory based on the pre-made casts. This ensures the most accurate restoration of the damaged tooth, taking into account individual peculiarities of the patient, and consequently greater comfort in the future. Tab is adjacent to tooth tissue so tightly that the risk of secondary caries is reduced to almost zero.
Tabs are produced in two ways – direct and indirect. In the first case, it is only an impression of the tooth requiring treatment. The second also take a picture of both jaws. This allows to take into account all the nuances of their contact with each other to use the obtained data in the manufacturing tab. As a result, it reproduces the original surface of the tooth.
The second method is appropriate if the tooth has been destroyed by more than 50%.
WHAT MATERIALS ARE TABS
For the manufacture of dental inlays are used such materials as metal, cermets, ceramics and composites. Let us consider each of the options.
These tabs do not differ from the seals. The only thing they win in front of them, is the ideal form, which is achieved in the dental laboratory.
Tabs from pressable ceramics or zirconium dioxide are considered the most effective, durable and beautiful. They are denser than other adjacent to the tooth tissue, eliminating the development of secondary caries. And of course, the ceramic looks more aesthetically pleasing metal.
Different coefficient of expansion under influence of temperature and shrinkage make the ceramic-metal tabs are not as effective. But they are cheaper.
INLAYS UNDER A CROWN
This is a special kind of tabs. Their function is not just to restore badly damaged tooth, but also to provide a solid Foundation for a crown. This requires increased strength and reliability. That is why this tab is made from metal. It is set in the cavity of the tooth, then the doctor makes a mold and sends it to dental technicians. This method is relevant if the tooth is destroyed almost completely.
WHEN IT IS BETTER TO PREFER THE TAB?
All the parameters of the inlays better seals. It is a fact. Perhaps, only in one case it is more logical to use a seal if a damaged baby tooth. Restore it by filling reasonable even for reasons of lower cost.
Teeth restored using tabs, do not require any special care. Sufficient to comply with the ordinary requirements of hygiene – brush your teeth regularly and thoroughly.
By the way, we mentioned in the beginning of the article that fillings eventually darken because of the porous structure. Tabs are not threatened, which means they will not need additional polishing, if you decide to go to the doctor-to the hygienist for professional cleaning.
