Dental crown
Dental Crown
A Dental Crown (pronunciation: /ˈdɛn.təl kraʊn/) is a type of dental restoration which completely caps or encircles a tooth or dental implant.
Etymology
The term "crown" in the context of dentistry, originated from the Latin word 'corona' which means 'garland or crown'. The term was adopted in dentistry to describe the restoration that 'crowns' or covers the entire or a significant part of the clinical crown of a tooth.
Description
Dental crowns are often needed when a large cavity threatens the ongoing health of a tooth. They are typically bonded to the tooth using a dental cement. Crowns can be made from many materials, which are usually fabricated using indirect methods. Crowns are often used to improve the strength or appearance of teeth.
Types of Dental Crowns
There are four types of dental crowns:
- Porcelain-fused-to-metal Dental Crowns
- All-resin Dental Crowns
- All-ceramic or All-porcelain Dental Crowns
- Pressed ceramic Dental Crowns
Each type has its own advantages and disadvantages, and the choice of crown depends on the specific needs and condition of the patient.
