What are Crowns?
Crowns are restorative dental appliances that are used to improve the functionality of the teeth. A tooth or a set of teeth that may be damaged due to decay can be restored by using crowns. Crowns will cover the entire teeth making it look natural and function like normal teeth.
Who requires crowns?
Crowns are generally suggested for patients whose teeth would have been damaged, discolored, severely decayed, or who have just undergone a root canal procedure.
What does a Crown look like?
A crown is a cap-like structure that fully covers the damaged tooth. Crowns can generally be of three different forms: all-metal, ceramic-on-metal, and all-ceramic. It takes a week’s time to get a customized crown designed in the lab.
How are crowns made for you and how long does it take?
The procedure that involves when you get a crown is the following:
- The dentist would first numb the area across your jaw bone where you will be getting the crown.
- The tooth gets drilled enough to create room for the crown.
- An impression of the tooth will be taken and send to the lab.
- The hole in the tooth will be filled with a temporary filling until the crown is ready to be inserted.
- After two to three weeks, the crown will arrive at the dentist’s office.
- The dentist will numb the area again where the crown must be placed.
- The temporary filling will be removed.
- The crown is then glued and fixed into position.
In this method, it would almost take a month to get a crown ready for you. The long wait to get your crowns ready can now be resolved by getting same day crowns.
What are same day crowns?
Same day crowns are the crowns that can be created by using a new technology called CEREC of Computer Aided Design and Computer Aided Manufacturing. It can be created as and when you wait in the office room.
This technology will allow the dentist to design and construct restorations like crowns, bridges, inlays/outlays in a matter of few hours.
The result of this technology for a same-day crown is a ceramic crown that is produced within an hour and glued into place where it is required.
How does this technology work?
The process to create a same-day crown using CEREC technology is quite different and faster.
- The area of the jaw bone where the crown is to be placed is first put on anesthetics.
- The dentist will drill the tooth to create a shape for the crown.
- Instead of making an impression of the tooth, a small camera is used to create a three-dimensional image of the drilled tooth.
- A computer program uses that to create an image of how the teeth will look like with the crown in place.
- The shape, size and the little ridges and indentations are sent across to another machine that mills the crown out of a chunk of porcelain.
- The result is ready to use crown that can be then inserted into the numbed area of the jaw bone.
