What are Crowns?
Crowns are restorative dental appliances that are used to improve the functionality and aesthetics of the teeth. A tooth or a set of teeth that may be damaged due to decay can be restored using crowns.
A crown usually covers the entire tooth, thereby restoring to its natural shape and functionality.
Who requires crowns?
Crowns are generally suggested for patients whose teeth 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 a 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 fabricated in the lab.
What are same day crowns?
Same day crowns are the crowns that can be created using a new technology called CEREC. It is an in-office crown manufacturing procedure that can be done in one or two appointments, and often in a day. They 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/onlays in a matter of a few hours.
The result of this technology 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 much quicker.
- The area of the jaw bone where the crown is to be placed is first put on anesthetics.
- The dentist will buff the tooth to create a space for the crown.
- Instead of making an impression of the tooth, a small camera is used to create a three-dimensional image of the buffed tooth.
- A computer program uses that to create an image of how the teeth will look with the crown in place.
- The shape and, size of the little ridges and indentations are sent across to another machine that mills the crown out of a chunk of porcelain.
- The result is a ready-to-use crown that can be bonded onto the teeth.
CEREC (Chairside Economical Restoration Esthetic Ceramic) is a method used by thousands of dentists worldwide in order to restore any tooth that is decayed, weak, broken, etc. to its natural strength and appearance. CEREC is an in-office crown manufacturing procedure that can be done in one to two appointments, and often in one day. The best part is it's done with all-ceramic materials that are tooth-colored in a single appointment.
Exam and Preparation
First, Dr. Yankie examines the tooth and determines the appropriate treatment. It could be a simple filling, or a full crown, depending on how healthy your tooth structure is and the clinical judgment of your dentist. Next, she will administer an anesthetic and prepares your tooth for the restoration, removing decayed and weakened tooth tissue.
This will involve taking a digital picture of the teeth. Instead of biting onto something to take an impression of the teeth, the dentist uses a camera to take a digital picture of the tooth.
The CEREC machine helps the dentist to create the restoration for your tooth. The CEREC 3D software takes the digital picture and converts it into a 3-dimensional virtual model on the computer screen. Dr. Yankie then uses her dental expertise to design the restoration using the CEREC 3D computer program. Within a few minutes, the restoration design data is sent to a separate milling machine in the office. A ceramic block that matches your tooth shade is placed in the milling machine. About 10 – 20 minutes later, your all-ceramic, tooth-colored restoration will be finished and ready to bond in place. Finally, she tries the restoration on your tooth to ensure proper fit and bite. The restoration is then polished and bonded to the prepared tooth. All of this is done in a single appointment! The dentist at Mill Valley, Dr. Frances H. Yankie, uses the CEREC technology.
