Dental crowns, also known as ‘caps’, help preserve the functionality and aesthetics of damaged teeth. When teeth are cracked, have extensive decay or root canal treated; there is usually insufficient tooth structure to treat the tooth with direct composite filling material or veneers. In this situation, a dental crown is inserted to ensure long term strength of this tooth.
What are crowns made of?
The material is selected based on a number of clinical factors. These include aesthetic demands, strength requirements, material durability and the restorative space available. The three predominant choices are all-ceramic, porcelain-fused-to-metal or gold crowns.
Visit 1. The dentist prepares the tooth and makes a moulded impression of the teeth to send to a dental laboratory. A temporary crown is fitted to protect the tooth while the final restoration is being made.
Visit 2. The patient returns to have the final crown cemented/bonded in place.
If an all ceramic crown is to be used and the practice has CAD/CAM technology, the crown can be scanned, designed then milled chair-side in a single visit. This means that no temporary crown or second visit is necessary.
