The choice of materials used for the manufacture of artificial crowns is quite wide today: porcelain, zirconium dioxide, but metal-ceramic remains the most popular and affordable.
Metal-ceramic crowns are a "cap" that completely repeats the anatomy of the tooth. The basis of the design is a metal frame, which is covered with porcelain on top, repeating the color of the tissue of neighboring teeth. An artificial crown is fixed to the tooth using a special composite or ionomer cement. If the tooth is severely damaged, it is pre-restored with a fiberglass insert. Metal-ceramic is also used to make bridges, beagle prostheses, and implant-supported crowns.
Pros and cons of cermets.
The advantage of metal-ceramic crowns is primarily in their strength. That is why they are most often fixed on chewing teeth. The disadvantages include their aesthetics. In general, porcelain-fused-to-metal crowns reproduce the anatomy of natural teeth well, but porcelain crowns are preferred for restoring anterior teeth. In the posterior region, where a combination of aesthetics and strength is required, zirconia crowns are the best choice.
