Genetics, hygiene and environmental conditions are the decisive factors in the state of the dentoalveolar system of man. People with perfect natural teeth by nature are very rare, most of them have to go to the dentist often due to the destruction and loss of teeth. This leads to the fact that a large number of people are confronted with the question of what kind of dental crowns are, because a low-quality chewing function leads to various problems and diseases of the body.
What are dental crowns for?
The cases when crowns are used include:
- partial tooth decay due to caries and its complications, when restoration with photopolymer material is impossible or not rational;
- complete destruction of the crown of the tooth with the remaining roots (using a dental crown on the pin);
- when pathological abrasion of teeth;
- as an integral part of the bridge;
- as the final stage of implantation of teeth;
- to eliminate aesthetic defects of teeth.
Types of dental crowns
Modern dentistry distinguishes crowns mainly on the material of manufacture. Rarely used types of crowns for dental prosthetics are:
- Metal tooth crowns. This is one of the old species that are rarely used in modern clinics. The reason is that crowns are too unaesthetic, especially on the frontal teeth. Although their advantages are low price, as well as resistance to chewing and nibbling. The main metals, of which such crowns are still made, are nickel, chrome, cobalt, gold.
- Dental crowns made of metal plastic and plastic have long been used for permanent prosthetics. In modern dentistry, such crowns are used exclusively as temporary. After all, their stamina is very doubtful. Simple plastic crowns are too quickly erased, due to the fragility of the material. In addition, they are stained with dyes from food and accumulate on themselves a large number of bacteria, which leads to the appearance of an unpleasant odor from the mouth . Metal-plastic crowns are also short-lived, because the coupling of metal and plastic is not strong and plastic eventually flies.
Modern types of dental crowns
Metal ceramic dental crowns
A few years ago these crowns were considered ultramodern, now they have descended almost to the lowest step in innovations in dentistry. Their advantage is a low price in comparison with other modern crowns, as well as good aesthetic qualities for lateral teeth and strength. The basis of the crown is a metal alloy, on top of which the ceramic mass is layered.
Whole-Ceramic Dental Crowns
On the question of which tooth crowns are best, almost every modern dentist will answer that all-ceramic. After all, their
The most modern and possessing the best qualities in terms of aesthetics and strength doctors call ceramic crowns based on zirconium. This transparent material has only one drawback - a high price. This is due to manufacturing technology - these crowns are manufactured on special milling machines controlled by computer technology, which guarantees a long service life and impeccable aesthetic qualities.
