Crowns can be either single or combined with each other in a bridgework. Single crowns, in turn, can be made of the following materials:

The patients who are most concerned about aesthetic and operational qualities choose metal-free ceramic crowns, and the optimum ratio of price and quality is metal-ceramic. 

If prosthetics of both the front and chewing teeth is required, then the best choice at an acceptable cost would be metal-free crowns on the front teeth and metal-ceramic teeth on the chewing ones.

Metal-plastic is usually used for temporary prosthetics.

The dentist may recommend installing crowns for patients with the following problems in the dental curve:

• The absence of one or more teeth.
• The destruction of the tooth crown more than half.
• Tooth deformation, color handling.
• Heavily erased enamel.
• Anomalies in the development of hard tooth substance.

Among the contraindications, only temporary states, after elimination of which it will be possible to proceed with the installation of crowns, are noted.

Depending on the materials used, the manufacture of different prostheses may differ slightly among themselves. In general, it is possible to distinguish the main stages, which almost always have a place to be:

• Consultation, diagnosis, drawing up a treatment plan.
• Sanitation of the oral cavity (treatment of caries, elimination of foci of possible infection, etc.).
• Tooth preparation (turning and, most often, depulping) or pre-installation of an implant with an abutment.
• Taking jaw casts.
• Making molds for the future prosthesis.
• Casting (milling) the crown.
• Try-in.
• Fixing.

In the absence of a tooth, the option of installing crowns on implants is usually used.
