What is a cerec crown?

If you are in need of a crown, but haven’t considered a CEREC crown, or are unsure of what they are, it’s important to take time to understand the science behind them, and why they are exceptional.

What is a CEREC Crown?

Many dental offices have technology which enables them to provide “computer-assisted design-computer-assisted manufacture”, or CAD-CAM crowns. CEREC is the company that is most known for this technology. This type of crown is created by a computer to perfectly fit your tooth, which prevents the need for the lab involvement in manufacturing the crown.

This technology allows the all-ceramic crown to be made while you wait, thus there is no need for a second appointment or temporary crown.

Facts About CEREC Crowns

  1. No single brand of same-day crowns. Though many people ask for same-day crowns by asking for CEREC crowns, this is an brand of same-day crowns, similar to Zoom Whitening, which is a brand of teeth whitening, but there is not a single brand of teeth whitening. CEREC means “Chairside Economical Restoration of Esthetic Ceramics”, but is not the only brand of same-day crowns. Often, the brand will use the phrase “same-day crowns”, or “crowns-in-day,” but these phrases are part of the marketing for the brand. However, the overall idea is the same with all restorations which take place in one dental visit. The office uses CAD/CAM technology to create it.
  2. CEREC crowns are billed the same as traditional crowns. Many people think the CEREC crown costs more than a traditional one. However, the opposite is true. For billing purposes, all dental procedures have billing codes. The billing code is the same for a CEREC crown and a traditional crown, therefore they cannot be billed any differently.
  3. They’re high-tech. CAD/CAM means a computer assists in the design. The program takes a picture of your mouth and plots out every detail. The measurements are exact. Then, the crowns are carved out by a machine in the office, with each new tooth starting out as a piece of material, oftentimes composite, zirconia, ceramic, or acrylic polymer, which is the same base for traditional crowns.

When operated and placed by an experienced cosmetic dentist, CAD/CAM crowns are a quick and efficient way to improve your smile, while maintaining a natural look and feel.

My crown keeps falling off

I had a CEREC crown placed. However, it has come out several times within the last year. Finally, after the fourth time, I consulted a different dentist, who replaced the crown with a zirconia porcelain crown, but it, too, has come out several times. The dentist suggested a full porcelain crown, stating that the cement is adhering to my tooth, but not the crown. He indicated that the all-porcelain crown is rough of the underneath and would, therefore, bond to the cement more effectively. I’m unsure of what my next step should be, but I am tired of the trouble these crowns have caused. What do you suggest I do?

Thank you,

Kodi,

The CEREC crown, or same-day crown, is created by a computer in the dental office, the day of your appointment. When prepared and adhesed correctly, the crown will remain permanently affixed to the tooth. The material of which your crown is made is not indicative of how permanent the bond will be. Whether your crown is porcelain, gold, CEREC, or zirconia, all are made to stay permanently.

However, there are two factors that can determine if a crown will stay on permanently or not. They are the bonding strength of the cement, and the shape of the prepared tooth. The most important of these is the shape. If the tooth is prepared with little taper, a crown can be adhered with a weak cement, and it will stay permanently affixed. However, if there is a lot of taper, even some of the strongest cements will have difficulty staying on.

This is not implying that getting a solid bond between the crown and tooth would not solve your problem. The cement’s strength is important. But, when a tooth is prepared with good retention form, the crown will not fall off multiple times in one year. This indicates that your tooth may have been prepared with retention form that is insufficient.

To move forward, it would be a good idea to consult a dentist experienced in placing crowns that will stay on.

CEREC Crowns help with dental anxiety

If you are a person who suffers from dental anxiety, and haven’t visited a dentist in quite some time, you may not be aware of CEREC crowns, and how these restorations are are changing dentistry and lives.

CEREC crowns are made in the office

It used to be that a crown could only be done by going into the office for multiple visits. The doctor would removed the decay and/or damage, take impressions, and fit you for a temporary crown in the first visit. Your impressions would then be sent to a dental lab, where your restoration would be created, over a two-week timeframe. While some crowns remain this way, CEREC crowns are different.

Years ago, the only option when you needed to have a crown done was to go into the office for two visits. On the first visit, the doctor would remove the decay or damage on the tooth, build it up if need be, take impressions, and fit you with a temporary. Then, your impressions would get shipped off to a dental lab which would then craft your restoration over a period of two weeks. Some crowns are still this way, but CEREC crowns are different. These crowns are made in the office using CAD/CAM technology and a milling machine, allowing your crown to be created and placed all in one visit, easing the anxiety of a dental patient who may be troubled by the idea of multiple visits to the dental office.

Impressions are taken digitally

Often, people with dental anxiety have strong gag reflexes, or aversions to the impression process. The use of the CAD/CAM technology, allows the impressions to be taken digitally, similar to having a photo taken.

Can be combined with sedation dentistry

Nitrous oxide is a helpful way for patients with mild dental anxiety to feel more relaxed and comfortable. It takes effect quickly, and wears off almost immediately after treatment. For those patients with a more intense dental anxiety, conscious sedation will place you in a deeply relaxed state.

Crowns without a temporary

I needed to get a dental crown. My temporary crown has fallen off. Of course, my know it all sister told me if I’d have gotten a cerec crown I wouldn’t have needed a temporary to begin with.  I’m sure she’d correct (she always seems to be), but can you tell me what this cerec thing is?

Nate,

I have a sister like that. As much as I hate to tell you this, she is right. CEREC crowns are milled at your appointment by a computer. They’re generally ready in about twenty minutes.

Because they’re done by computer, they generally will fit better as well.  You’ll have to find a dentist who uses CEREC technology.

Hopefully, your current dentist took care of your temporary crown.  You don’t want to leave that off because it can throw off your bite and your permanent crown won’t fit.
