Crowns
A crown is a type of dental restoration that completely caps or encircles a tooth or dental implant, and is bonded into place with a special cement. Crowns are referred to as indirect restorations, because they are made in a laboratory, in several stages, rather than directly in the mouth. After preparing the tooth the dentist takes an impression and sends it to the laboratory, where the crown is made to the requested specifications. The finished crown is bonded to the tooth using a special cement. Crowns are usually used to restore the integrity of teeth that are damaged by large cavities or are broken, and to prevent further damage. They can also be made as a means of anchoring other dental restorations. |
