Crown
Crown (medicine)
Crown (pronunciation: /kraʊn/) in the field of medicine and more specifically in dentistry, refers to a type of dental restoration which completely caps or encircles a tooth or dental implant.
Etymology
The term "crown" comes from the Old French word 'corone', which was derived from the Latin 'corona', meaning 'garland, crown'. The term was adopted in the field of dentistry due to the resemblance of the dental restoration to a traditional crown worn on the head.
Types of Crowns
There are several types of crowns used in dentistry, including:
- Ceramic Crowns: These are made of a porcelain-based material and are used primarily for restoring front teeth due to their superior aesthetic qualities.
- Porcelain-fused-to-metal Crowns: These have a strong metal structure and are covered with a porcelain layer for aesthetic purposes.
- Gold Alloys Crowns: These are a mixture of gold, copper and other metals, providing a strong bond to the tooth.
- Base Metal Alloys Crowns: These are made of non-noble metals that are highly resistant to corrosion and make for a very strong crown.
