Which crown is better?

A dental crown is a microprosthesis coveringthe outer part of the tooth. The installation of dental crowns is the most accessible and widespread method of dental prosthetics. Crowns are used not only to repair damaged or partially destroyed teeth (in the case when the existing defect can not be eliminated with the help of a dental insert or a seal), but also to correct the shape of healthy teeth and correct their incorrect location.

Types of dental crowns

Depending on the material from which the dental crown is made, the following types are distinguished:

metal crowns;
non-metallic crowns;
combined crowns (metal-plastic, metal-ceramic).
