The metal ceramic crown is made of high-strength material with high aesthetic characteristics. Typically, this type of crown is used with a high degree of tooth decay, that is, when it is necessary to create a strong and lightweight framework.

The service life of the crown depends on how correctly the design was chosen and made. In the service life of the key role played by the material from which the metal-ceramic crown is made. On average, the operating period of such a product is from seven to twelve to fifteen years. The main reason for the change of the crown is the inflammatory process underneath it, the cleavage of the ceramic enamel.

Metal-ceramic dental crowns are made individually for a specific customer. First they make a cast of wax, then a metal base is cast in the dental laboratory, which is covered with ceramics. This kind of crowns, as a rule, is installed on a metal base (implant or pin in the tooth). Thanks to this, the most durable construction is created. Sometimes ceramic-metal crowns serve as the basis for bridges.

For the construction of the frame, light, but at the same time very strong metals - titanium alloy, palladium, gold, platinum are used. On a metal frame in several layers porcelain facing is applied, identical to the natural color of the enamel, possessing increased resistance to erasure, microorganisms, aggressive dyes. The tooth is covered on all sides by a crown, fixed on a special cement, which is used in dental practice.

Prosthetic dentistry using innovative materials is a great way to restore the functions, shape and appearance of the tooth. The question arises, how much does a metal-ceramic crown cost? So, the cost of metal-ceramics varies considerably, because different materials with different cost are used for manufacturing dentures. If a dental laboratory is installed in the clinic, this will significantly reduce the cost of the denture.
