A porcelain crown is a type of dental restoration which covers a tooth with a sizable cavity or after a root canal treatment or implant abutment entirely. Crowns are often needed the ongoing health of a tooth. Porcelain crowns are usually bonded to the tooth using dental adhesives. Porcelain or ceramic crowns can be either all porcelain or porcelain bonded to a substrate which can be Alumina or Zirconia, and are usually fabricated using indirect methods.
A porcelain crown is used to restore the functionality and esthetic of a tooth with excessive decay, protect a cracked tooth, or replace a pre-existing crown with a more esthetically pleasing option. The purpose of a crown is to encase a decayed or problematic tooth with an esthetic custom-designed material. Either way, they are very sturdy and long lasting.
One of the steps to crown a tooth involves sending a regular or digital dental impression of a tooth prepared by a dentist to a dental laboratory for fabrication the crown. The crown can then be inserted at a subsequent dental appointment. Using this two step method allows the lab technician to use superior restorative materials to fabricate a strong crown as well as his artistry skills to create a life like restoration, which would not be possible inside the mouth. The method of fabricating porcelain restorations may differ in the lab depending on what type of porcelain (ceramic) is used.
While inarguably beneficial to dental health, the procedure and materials can be relatively expensive. Talk to your dental care team to determine if you are a good candidate for a porcelain crown.
