Same-day Crowns: CAD/CAM and CEREC®
Chairside Economical Restorations of Esthetic Ceramic (CEREC®) has pioneered dental procedures. CEREC® is made up of a computer-assisted design (CAD) tool and a milling machine that gives our Charlottesville dentists the ability to create custom made ceramic dental restorations in little time.
The conventional crown procedure consists of the tooth preparation, messy impression materials, and the fabrication of a temporary crown. Then, the impression is sent to the lab and the patient waits 3-4 weeks for the crown to be fabricated. Once the crown is fabricated, the patient returns, having to be anesthetized again, and the crown is finally cemented.
With CEREC® technology, a digital impression means no messy impression material. In many cases, the crown is made while you wait, so you leave the office with your permanent crown! This saves you an extra trip to the dentist and prevents weeks of worry and careful eating with a temporary crown.
How does the CEREC procedure work?
Once you arrive at Downtown Dental, the area will be numbed and your dentist will carefully prepare the tooth to specific dimensions for your new crown. Using a high-quality camera, the dentist will acquire video of the tooth. A medical grade computer processes this information to make a 3-D model of your mouth.
Your trained dentist is then able to rotate and enlarge your tooth model to design a crown that is a perfect fit for your tooth. Once the dentist has designed your beautiful custom crown, a special milling unit will cut your crown out of a compressed porcelain block, which provides additional strength compared to hand stacked porcelain from the laboratory. This process takes around 15 minutes.
The crown is now ready to be tried in your mouth for fit and any adjustments made. The dentist may then add some custom coloring and glaze to the tooth before firing it in a special oven to achieve maximum strength. Your final crown will then be cemented before you leave. Ask your Charlottesville dentist if CEREC is an option for you!
Will CEREC® benefit me?
CEREC® benefits many patients looking for a ceramic dental restoration device. Some advantages include:
- Permanent (no temporary) and long-lasting dental restorations
- High-quality devices that save more natural tooth
- Less-invasive procedures for patients
- Fewer injections resulting in less discomfort for patients
- Fewer dental visits means fewer costs to patients
- Biocompatible solutions that do not harm the body
- No horrible-tasting impressions
- No time-consuming transfers to and from a lab
Some exceptions apply. If you have a history of breaking these types of devices or you have a deep bite, you should speak to your Charlottesville dentist because these products may not be the best option for you.
How long do CEREC® dental restorations last?
We know that CEREC® devices last for over five years. Now, research shows that most CEREC®-created dental restorations may last for more than 10 years.
