Different Crowns for Teeth.

What types of prostheses are there, which ones are better to put?

Crowns are fixed to the visible part of the element using a special dental composition. Prosthetics with crowns allows you to simultaneously restore the chewing function and the anatomy of the dentition.

Crowns for teeth differ in material and, accordingly, in price. To decide which crowns are better to put in a particular clinical case, it is necessary to identify the pros and cons of each type of prosthesis

Plastic crowns.

Such products are used as temporary crowns. They are light, quickly manufactured and cheap. The structures are fixed on sharpened teeth or implants (for a while, while a permanent prosthesis is being prepared).

The mission of temporary crowns is to evenly distribute the chewing load on the dentition, while reducing the risk of bone atrophy in the jaw and speeding up the process of getting used to a permanent prosthetic structure in the future.

Metal-plastic crowns.

The most inexpensive option of prosthetics. The crown is based on a metal alloy (cobalt, chromium, nickel). To give the prosthesis a natural appearance, the base is covered with a layer of plastic. With insignificant chips of the material, the repair of the product can be carried out directly in the patient's oral cavity.

Metal-plastic structures are not strong enough - they can serve a person up to 3 years. Over time, the products lose color, slightly increase in size, and can cause allergies.

Metal ceramics.

Metal–ceramic crowns are a true “golden mean” - the products are quite reliable and aesthetic. The surface of the prosthesis is ceramic, and the base is a metal alloy.

In the manufacture of prostheses made of precious metals (gold, silver, palladium), you can count on a more natural design. In this case, the metal base will not give off a grayish tint through the coating, as in the case of conventional metals.

The relatively low price of metal-ceramic prosthetics with its acceptable functional and aesthetic indicators makes this method of tooth restoration the most popular. However, before making a choice in favor of metal ceramics, it is worth considering the risk of developing an allergy to metal, as well as the minimum probability of chipping the ceramic coating.

Metal crowns.

This type of prosthesis is less popular nowadays. The product has the form of a metal cap, which is put on a damaged tooth or titanium root. The strength of these crowns can be envied. A significant disadvantage of such products is their unaesthetic appearance: the metal in the oral cavity is difficult to hide from prying eyes.

The prosthesis is made in a dental laboratory. It is based on steel, titanium, as well as gold and platinum. In dentistry , there are two types of metal crowns:

stamped. These are standard caps, which are given an individual shape already in the patient's oral cavity. The products have thin walls, so they are quickly erased and are very rarely used in practice;

cast. Designs are prepared on the basis of personal casts. This technique makes it possible to make prostheses that fit perfectly to hard tissue, eliminating the spread of bacteria in the space between the prosthesis and the dental tissue.

In the process of manufacturing metal crowns, spraying technology is often used. The material for these purposes is chosen at the request of the patient (gold, zirconium dioxide, plate).
