Is the process different for restoring CEREC crowns compared to other crowns?

CEREC Crowns

CEREC crowns are prepared in a similar way that traditional crowns are, with a few exceptions.  When the tooth preparation is finished, instead of taking an impression with a mouthful of putty, a thin layer of powder is sprayed over the tooth and an optical picture is taken using a 3D camera.  The biggest difference however is the fact that a CEREC crown can be completed in one visit, where a traditional crown requires a temporary crown to be placed and a follow up appointment to place the real crown.

Cerec crowns vs lab-made crowns

Cerec is one of CAD/CAM technology that uses computer software to plan the shape of the crown and later reproduce the same exact shape in porcelain. Cerec has strong research showing the high success rates of these crowns. However, more and more often we are dealing with failures of such crowns, due to their lower strength in comparison to classic lab made crowns.

The process of prepairing the tooth is the same. The impression is taking digitally without impression material, and the crown is fabricated right in the office. It saves time and money in the beginning of the treatment, but does not give predictable long-term results as standard technology.

Yes there is a difference in the restoration process.

With cerrec crowns the difference comes in the technology used to create the crown. The tooth is prepared similar to an all porcelain crown that is sent to a lab. Instead of taking an impression and using a not so pleasant material; we will use an intraoral camera that scans the prepared tooth. The scan is usually very accurate. Once the scan is saved in the ckomputer the crown is designed and fabricated with you in the chair. We are able to tailor your crown with your direct input because you will remain in the chair for this process. No more temporaries that come off because when you leave you will have your permanent crown. Also no need for a second crown appointment. They are great. DR.C

What are Dental Crowns?

A crown is a prosthetic postioned over a tooth to create a smoother look and enhance strength and durability. When a tooth is cracked, has an old filling, or is severely decayed, the placement of a crown is often recommended. Crowns strengthen and protect the remaining tooth structure and can improve the appearance of your smile. Types of crowns include the full porcelain crown (ideal for use on the front teeth), the porcelain-fused-to-metal crown and the all-metal crown (ideal for use on the back teeth).

Why patients are choosing CEREC?

CEREC by Sirona Dental Systems is the world's only system for the fabrication of all ceramic dental restorations in one office visit. With CEREC, you can be in and out in a single visit with a permanent crown! For you, the patient, this means fewer injections, less drilling, and less time out of your hectic schedule for dental care. So, why are thousands of people world wide choosing the CEREC restorative technique for their dental needs?

Single Appointment Dental Care

Most dental restorative methods require more than one visit to the dentist. This means that on the first visit, you get an injection of anesthesia, your tooth prepared, an impression taken, and a temporary restoration put on your tooth. You make a second appointment for a couple of weeks later, get another injection, have the temporary pried off (if it hasn't fallen off already), and have a permanent restoration put on. Why go to the dentist a second time when you don't have to? With CEREC, the procedure is done in a single appointment, start to finish.

Finest Dental Materials

A CEREC tooth restoration isn't just convenient, it is also healthy. Many years ago, dentists had few options to repair decayed and damaged teeth other than amalgam, gold, and other metals. With CEREC, your dentist can use strong, tooth colored ceramic materials to restore your teeth to their natural strength, beauty, and function. These materials closely match the composition of natural tooth structure. This means when you eat hot food and then drink something cold, the restoration and tooth expand and contract at almost equal rates. So, your tooth does not crack, and you can go on enjoying your evening. Also, the materials are chemically bonded to your tooth, so your dentist can save as much healthy tooth tissue as possible while providing you with a dental restoration that strengthens your tooth.
