Dental crowns are a restoration that completely covers the portion of a tooth up to the gum margin. It can also be placed on a dental implant.
Once the dental crowns are in place, the appearance and structure are almost identical to the rest of your natural teeth, therefore they restore not only functionality, but also aesthetics.
Dental crowns are permanently cemented to either the implant or the tooth, which have previously been worn down to reduce its size. The tooth or implant with a crown feels, acts, and has the appearance of a natural tooth.
In the market, there are several materials used to create the internal structures of dental crowns; for example, the noble metal and recently, zirconium.
The noble metal is an alloy of chromium with nickel, which has been used for years in dental laboratories for both crowns and dental bridges, obtaining excellent results. Once the noble metal framework is created, it is coated with porcelain to create the white appearance of a tooth.
The use of zirconium is one of the new innovations in materials for the manufacture of dental crowns, which has been widely accepted due to the aesthetic results obtained, especially because of its translucency.
Both porcelain dental crowns with noble metal and porcelain with zirconium can be used to restore any piece. Since both materials provide the same resistance and strength during the masticatory process, the dentist will indicate which will be the best alternative for the restoration.
